What Are Requirements Of The Tower Type Online Ups (6-10kva) Pf0.8/0.9 For Its Inverter?

UPS power supply is a kind of power protection equipment with energy storage device, inverter as the main component, and stable voltage and frequency output. The inverter is centered located between the rectifier and the static switch in the UPS system. It is the core component of the UPS power supply.​ It mainly converts the DC power output by the rectifier or the battery into 50Hz AC power, and then sends it to the static switch and then supplies it to the load equipment. So what are the requirements of the Tower type Online Ups (6-10KVA) PF0.8/0.9 for the inverter?

Generally, the requirements of Tower type Online Ups (6-10KVA) PF0.8/0.9 for inverter are as follows:

(1) The voltage of the output AC power should be stable. Whether it is the input voltage fluctuation or the voltage fluctuation caused by other conditions, the inverter output voltage is required to be within the stable accuracy range, which is generally ±2% in static state.

(2) The output voltage and frequency of the inverter should be adjustable. The output voltage adjustable range is ±5%, and the output frequency adjustable range is ±2Hz.

(3) It has overload protection capability, generally 125% to 150% overload. When the overload is 150%, it should last for 30s, and when the overload is 125%, it should be able to last for 1min or longer. The overload protection capacity of Burke UPS power supply can reach 15% when working normally, 10m at 125%, 1m when 150%, and 1s when 200%.

(4) The frequency of the output AC power should also be within the stable accuracy, generally ±o.5% in static state.

(5) The output waveform is a sine wave to reduce harmonic distortion. Generally, the small output distortion rate should be controlled within 7%, which is conducive to reducing the size of the filter.

​6) It can recover the commutation energy and minimize the commutation loss to improve the efficiency of the inverter.

7) With short circuit, overload, overheating, overvoltage, undervoltage etc other protection and alarm functions.

​8) The starting should be stable, the starting current should be small, and the operation should be stable and reliable.
