Main Technical Parameters Of Ups

Main Technical Parameters Of Uninterruptible Power Supply(UPS)

Input characteristics:

1. Input voltage range A wide input voltage range can reduce the chance of battery discharge and extend battery life.

2. Input power factor A low power factor leads to large input reactive power, and harmonic current pollutes the power grid, affecting and interfering with other devices.

3. Allowable range of main power frequency.

4. Input current harmonic component. (PFC, 6/12 pulse transformer)

Output characteristics:

1. Static stability. Large is 1%, small and medium is 2%.

2. Output transient characteristics. Large is 5%, small and medium is 8%.

3. Output overload capacity. (For example: overload 125% 5MIN; 150% 10S)

4. Output power factor. (0.8, 0.9, 1)

5. Output voltage harmonic distortion. Typically within 3%.
