What is the power UPS power supply? What is the difference between it and conventional UPS power supply?

UPS devices are usually protected against excessive voltage and low voltage.

UPS (Uninterruptible Power System), that is, uninterruptible power supply, is a kind of energy storage device, inverter as the main component of the constant voltage constant frequency uninterruptible power supply. Mainly for a single computer, computer network systems or other power electronic equipment to provide uninterrupted power supply. When the mains input is normal, the UPS will be powered by the mains supply to the load, this time the UPS is an AC mains regulator, and it also charge the battery to the machine; when the electricity interruption (accident power failure) , UPS immediately put the battery power, through the inverter conversion method to continue to supply 220V AC load, so that the load to maintain normal work and protect the load soft, the hardware is not damaged. UPS devices are usually protected against excessive voltage and low voltage.

the difference: 1, the power UPS itself without a battery pack, directly using the DC screen busbar hanging on the battery pack, so the power UPS can not set the charger. 2, because the DC screen battery bus to the ground insulation detection, so the power UPS input / output must have isolation transformer. 3, power dedicated UPS uninterruptible power supply size is generally 800 * 600 * 2260 standard power cabinet, from the outside through the glass door can see the status of internal switches and lights. Output feeder circuit number and capacity. 4, power dedicated UPS uninterruptible power supply generally by the power UPS host, bypass regulator cabinet, the output feeder cabinet and other three parts of the group screen supply. 5, due to the power plant DCS system load most of the single-phase load, single-phase load distribution line is simple, easy maintenance. So most of the electricity dedicated UPS output single-phase 220V, the capacity is generally within the scope of 80kVA.
