The differences are quite simple. The fused unit has 3 x Amp fuses on the input of the unit. The Standard unit does not. Both units have the same output circuit breakers for protection and the same number of outlets and power capacity. The kAIC rating, or interrupting current rating, in layman terms, is the amount of current that goes through a component without it catching on fire.
Circuit breakers and fuses are designed to protect your equipment from damage in case of a short circuit or circuit overload. Breakers can withstand only a certain amount of current. All circuit breakers and fuses have an interrupting capacity rating.
If you install a circuit breaker with a KAIC rating that is too low for the connected load, it may not be able to protect the circuit from damage if overloaded and create a potential fire risk. Typical PDUs range from to amps of interrupted current. This works for most loads and electrical systems, but some Crypto Mines have a large capacity of power In close proximity, which can create the need for higher than standard kAIC ratings. Before the launch of the new fused Minotaur, there were no commercially viable or cost-effective solutions for solving this problem.
This far exceeds even the highest rating that would be required. So in summary, if you do not require a higher than 10, amp interpreting current rating or do not want an extra layer of input protection, the standard Montuar will work perfectly for you.

Thread Thine Path. Aurora, once a prosperous kingdom has fallen. An ancient darkness reborn savages the land with brute force. Crops decay, winds scream with rage, and the dead stir. In his lust for power and forbidden knowledge, a king has forsaken his people to ruin. We recommend using wye power whenever possible. Beyond being easier to balance your load with a wye configuration, circuit breakers at the branch level are much cheaper as they only are required to breaker 1 hot line, vs 2 hot lines in a delta configuration.
What power is typically available from my utility and what voltage should I use? This is a question I get every day. What voltage will my power company give me and what is the best one to use? This is a pretty complex question. Power companies generate power at a main plant, whether it be coal, solar, wind or hydroelectric.
This power is distributed via high voltage power lines over long distances to sub-stations. Sub-stations are a collection of transformers and switchgear that route the power to residential and commercial buildings. A large facility may even have its own sub-station. The voltage at a sub-station will usually be between 12,V and 36,V. When power gets to a building, there is a transformer that drops the medium voltage down to a useable low voltage.
This presents a problem for crypto farms. Even if the PSU could run on V, it requires a higher current to achieve the same wattage, which is problematic when it comes to price and size of circuit breakers in your power system. This power configuration provides the highest efficiency and has the lowest circuit breakers costs in your main panel and the branch breakers in your PDUs.
When setting up a crypto mine it is important to understand all of the critical components that are used and their relationship to each other. A complete power system starts with a mains transformer. This transformer is used to step the utility voltage from 12,V,V down to either V, V or V. After the main transformer, there is a main disconnect.
This is a large switch that is used to cut all power off for maintenance or in an emergency. Not only is it a good idea to have a main disconnect, but it is also usually required to meet electrical codes in the USA and Canada. After the main disconnect, the power is fed into a main circuit breaker panel. After the circuit breaker panel, the power is routed to PDUs. In summary, the major components of a crypto mine power system are the mains transformer, the main disconnect, a circuit breaker panel, a PDU, and a PSU.
A transformer has 5 major specifications you need to consider. This is the voltage that is provided by the utility. This is the voltage that will power your crypto mine. Power rating is expressed in kVA, kilo volt-amps. In an isolation transformer, the windings can be constructed as a step-up or step-down transformer to match the load in the power system for your crypto mine.
Some advantages of using an isolation transformer are that it prevents the attached electronics from getting harmonics and spikes from the main input power. There is no connection between the power lines and earth ground. With an isolation transformer, there is no danger in touching the live lines while the body is earth grounded. By connecting the electrical system ground to the neutral conductor on the transformer secondary output , it eliminates neutral-to-ground voltage and noise.
This creates the cleanest possible power for your PSUs. An autotransformer is lighter in weight and smaller in size as it has fewer windings and a smaller core. In addition to being lighter and smaller, an autotransformer is less expensive than an isolation transformer. The advantages listed above are for autotransformers with a voltage ratio up to , meaning the voltage drop is less than that ratio.
Beyond this range, an isolation transformer is more economical. There is no isolation between the primary winding and the secondary winding. This means that the protection of the equipment is dependent on the electronics that are attached to the transformer. Standard PSUs have enough protection built in to be powered by an autotransformer. The primary and secondary side of an autotransformer share a common end, if the neutral side of the primary voltage is not grounded, the secondary side will not be either.
The disadvantage of this is if a failure of the transformer occurs it will result in the full input voltage being pushed to the output. This failure mode would damage any attached PSUs. The good news is that there are very few cases where an autotransformer has a failure of this magnitude. The NEMA rating of an enclosure refers to its ability to repel water, dust, and temperature variations.
When given a choice, choose an isolation transformer if you are dropping high voltage, 12,V,V down to V, V or V. Use an autotransformer when you are dropping V down to V, V or V. A circuit breaker panel is often an overlooked component of a power system. This is the heart of your power system and careful consideration needs to be taken while selecting what type of panel to use and what type of circuit breakers to install in it. There are five major areas to consider when selecting a circuit breaker panel.
These enclosures can come in wall mount or free-standing models. Typically, freestanding models are used for kVA rating and higher and wall mount enclosures are used for kVa or less. Wiring is usually used in lower power rated circuit breaker panels. Wiring a panel is costly but makes the panel easier to customize.
Compliance-wise a wired panel is easier to get UL listed. Wired panels can be listed to UL A, which can be done by the manufacturer without having to actually send the panel out to be tested. This helps equalize the price increase usually associated with wired panels.
Bus bar panels use a thick copper bus bar to route power internal to the panel. Bus bars have to be machined, which makes it more costly for small quantities, especially if the panel is customized. Bus bar circuit breaker panels are UL listed to UL This certification cannot be done by the manufacturer.
To achieve a UL listing, the manufacturer has to have an NRTL nationally recognized testing laboratory test the panel and certify it. This can be a large cost driver, especially if the panel is customized. When given a choice, choose a wired panel if it is kVA or less and if the panel needs to be custom not standard from the manufacturer. Choose a bus bar panel if the power is larger than kVA.
If the panel is custom and over kVA, weigh the cost differential between having multiple wired panels and a single bus bar panel. A thermal circuit trips based on the heat on a power line. Heat has a direct correlation to the current that is flowing through a wire. When the temperature reaches a certain point, the circuit breaker trips. The advantage to a thermal circuit breaker is the cost, they tend to be more economical. The disadvantage is that they are sensitive to ambient temperature and have to be derated properly to ensure you are getting adequate protection.
The higher the ambient temperature, the current that is required to trip the circuit breaker is lower. If your environment is temperature-controlled choose a thermal circuit breaker to provide more value. First, you must understand the type of circuit breaker you are using. As described above, choose a circuit breaker based on your ambient temperature. If you are using a thermal breaker, refer to the manufacturer's specification on temperature derating.
Circuit breakers come in 1, 2, and 3 poles. You use 1 pole per phase in your power system. The amount of poles you use is also dependent on the PDU that is being used in your crypto mine. If the PDU has a single phase input, then you would use a 1 pole circuit breaker. If you are using a dual phase input PDU, you would use a 2 pole circuit breaker.
A 3 phase PDU would require a 3 pole circuit breaker. It is important to know that each pole is rated for the circuit breakers current. For example, a 3 pole amp circuit breaker is capable of carrying amps of single phase load, or amps per pole.
PDUs are the most important part of your power system. PDUs are the final line of defense against surges, swells, spikes, and noise. The selection of a PDU drives changes through your whole crypto farm. For example, if you are using a 3 phase input PDU, you would have to ensure you are using a single phase circuit breaker panel with 1 pole circuit breakers.
One of the largest problems that crypto farms experience when selecting a PDU has to do with a very limited selection of PDUs available on the market that is capable of carrying the amount of current that is required for multiple PSUs. PSUs usually require between 5 and 10 amps each. The highest current PDU available on the commercial market that is readily available is usually 30 amps. This creates a lot of problems and additional costs.
The first problem is that 30 amp PDUs are typically expensive. Having multiple 30 amp PDUs will drive costs to ranges that are unacceptable for most crypto mines. The second problem is that the more PDUs you have, the more wiring and circuit breakers you have to have. There are many factors to consider when selecting a PDU. A vertical mount enclosure is typically mounted horizontally to run longways across a shelving rack that houses miners. By mounting the PDU long ways, it provides a better spread of outlets across the rack and takes up the least amount of space.
These types of enclosures are popular in server racks in data centers and do not usually work well in a crypto mine environment. When given a choice, based on your rack set up, always choose a 0U vertical mount PDU.
It is crucial to choose the PDU that matches your phase configuration. It is important to note, that usually a 3 phase input PDU will output a single or dual phase, depending on if the 3 phase input is a delta or wye configuration. A wye configuration will have a single-phase output and a delta configuration will have a dual phase output.
Both single and dual phase power is sufficient to power a PSU. Overvoltage protection is provided by MOVs metal oxide varistors. At a minimum, it is important to have circuit protection on each phase of your PDU. Some PDUs have both input and output breakers, but this is not required. Only output breakers are needed for a crypto mine PDU. It is important to use a PDU that has outlets that are rated for your voltage. A standard R wall outlet is not sufficient to power a miner. These outlets are rated up to V single phase or dual phase.
For example, a 30 amp PDU is sufficient to power up to 26 amps of load. In summary, you should always choose the highest current PDU available, while taking into account the space you have available and the way you must mount your PDU onto your rack. Wiring all of the major components of your power system together is a challenge. You have to take into account the length of the wire run, the voltage, and current that you are using, and the number of conductors.
There are many different types of wire and each type has a place in your power system. This wire is a single conductor, which means that each wire is carrying a single line. To complete power wiring you will need a minimum of 3 wires, one for line, one for neutral and one for ground for a single or dual phase system. In a dual phase system, the wiring would be 2 lines and 1 ground. THHN is bundled together in a wiring conduit, hollow plastic or metal flexible tubing that is run from point to point.
These cables usually require a bigger conductor size to carry the same amount of current as a single conductor cable and are typically more expensive these using a THHN single conductor bundle. Use the below chart to pick your wire gauge and always consult with your installation company or an electrician to ensure you are meeting any local electrical codes. Many control and monitoring software packages exist to manage the power in your crypto mine. These powerful features come at a cost and should only be deployed when absolutely needed.
When deciding on whether or not to use control and monitoring software you need to weigh the costs of having a person on-site vs the initial costs of managing your crypto mine remotely. Typically, in crypto mines smaller than 5 megawatts, a remotely managed power system is a good value.
If the crypto mine is larger than 5 MW it usually makes sense to deploy remote control and monitoring software. Additionally, if your mine is a co-location, remote control and monitoring software can be used for billing purposes if you bill based on power usage and to ensure that your client's miners are not over hashing or using more power than you allocated to them.
To comply or not to comply, that is the question. There is a simple answer to this question. When given a choice, always choose a product that is NRTL listed. Customized product has a few barriers to being NRTL listed. Firstly, compliance testing is expensive and labor-intensive. Secondly, many manufacturers will not NRTL list a short-run customized product due to the labor and paperwork required.
