What do you mean by "ups" and "2000"?
UPS-2000:UPS - Uninterruptible Power System, that is, uninterruptible power supply, is a kind of energy storage device, inverter as the main component of constant voltage constant frequency uninterruptible power supply. Used primarily to provide uninterrupted power supply to a single computer, computer network system, or other power electronic equipment. When the power input is normal, UPS electric voltage supplied to the load, the UPS is an AC power regulator, it is also the built-in battery; when the power interruption (outage), UPS will immediately machine battery power through the inverter conversion method continue to supply 220V AC power to the load, the load to maintain normal working load and protection of software and hardware is not damaged. UPS devices usually provide protection against too large voltages and too low voltages.
2000 - 2kVA, that is, 2000W. This value is apparent power (rated power, the actual power ratio is small).
Ups-2000 one is the UPS power model, such as Mount MT500Two is the power of UPS, how much can drive the load, this is a rated power, the actual use is not so high.
