FAQ：
What is a UPS?
A UPS is an electrical device that provides continuous, conditioned, uninterrupted power to acritical AC load. It also provides isolation between the input and the output. It consists of aRectifier/Battery Charger, Battery System, and inverter. The Battery Charger converts incoming commercial/utility AC power to DC power. This power is then supplied both to a Battery system and an inverter. The inverter then converts this DC power back into AC power which is fed to the critical load(s). The Battery is an emergency DC supply that is connected in parallel with the output of the Battery Charger, and supplies the DC power to the inverter (without any switching) in the event that the incoming commercial power is lost or outside of specified tolerances.
A true UPS is an on-line system, which means that under normal operating conditions, the power flow is through the Battery Charger, then through the inverter to the load. This differs from off-line, or stand-by systems, which are designed such that under normal conditions, power for the load is supplied directly from the commercial power source, NOT through the inverter. Depending on the design, and cost, the power may be conditioned by means of a Voltage Regulating Transformer or Power Conditioner placed in the power path between the commercial power source and the load. In an off-line or standby system, the inverter only supplies power to the load if the utility power fails. The Battery then picks up the inverter load for a finite period of time (typically 15–20 minutes).When the battery is depleted, the inverter will turn off, and the load will go down.
In order for a power supply to be considered a true UPS, it must accept three sources of power. The first source is the commercial, or utility, power that supplies AC power to the Battery Charger; the second is the Battery, which provides emergency DC power. The third source is a bypass, or alternate, AC source, which provides emergency AC power to the load if the inverter is unable to supply power, either because of an inverter failure, or a fault on the load. Under these conditions, the load would be automatically transferred to the bypass source via a static (electronic) transfer switch. The bypass source also supplies power in the event that the load is transferred manually from the inverter via a manual maintenance bypass switch.
A true on-line UPS is also referred to as a double conversion system. This means, as the name implies, that the power is converted twice. First it is converted from AC to DC at the Rectifier; then it is converted back from DC to AC at the inverter. Another common term is reverse transfer. This refers to the fact that the load, under certain conditions as described above (faults, equipment failure, or manual operation), is transferred back onto the commercial/utility power source.
Again, this differentiates it from an off-line system where, under normal operation, the load is powered from the utility source.
Why single phase instead of three phase?
UPS systems are available in a variety of single phase, three phase, and so-called split phase voltage configurations.
However, many loads in the industrial market are single phase only – particularly DCS, SCADA, and PLC applications. In years past, the EDP market – especially large main frame computer applications gave rise to a need for three phase UPS systems. There are, obviously, some three phase industrial loads, notably large motors, but by and large most industrial situations require single phase.
This is actually good news, because a single phase UPS offers some advantages over three phase systems. First, the fault clearing capability of a single phase inverter is approximately three times greater than a three phase unit. Downstream fault protection coordination is also easier to accomplish with single phase.
Second, there are no loads to balance. When using a three phase inverter to drive single phase loads, care must be taken that loads are balanced within a few percent of each other. Load imbalance can lead to voltage regulation that is out of spec, as well as increased harmonics, which can lead to distortion in the output waveform and/or overheating.
Single phase distribution panel boards and switchboards are less expensive, smaller, and easier to work with than three phase units. Again, since industrial controls systems for the most part consist of single phase loads it probably doesn’t make a lot of sense to install three phase panels and inverters in the distribution system. This is likewise true for so-called split phase distribution systems. Many panel boards are rated for 120/240 volt operation. Therefore, many electricians think that they need to provide an inverter (UPS system) with a 120/240 volt output, rather than a straight 120 volt output, even though the actual loads are only 120 volts. In reality, a 120 volt unit is what they need – all they need to do is split the loads at the panel board. Many panel board manufacturers will make a straight 120 volt panel if requested to do so, usually at no extra cost.
Although it may be a trade-off at higher power levels, it can be easier and less expensive to run cables for a single phase system. The trade-off comes when taking into consideration the breakers and cable sizes.
In general, unless you truly have some three phase loads, then, it is usually a better bet to use a single phase UPS, rather than three phase. Check with your UPS supplier to make sure that
they can provide a single phase system, even at higher power levels – say 75 or 100kVA. Even at those ratings, the advantages of single phase may outweigh the perceived installation cost savings of three phase.
