FAQ        

 
The various components of the UPS are listed as follows:
 

1. Surge suppressor-Suppresses any surges and spikes to protect the load.
2. EMI / RFI Noise Filter greatly reduces noise and transients on the power line
3. Charger-Maintains the battery and keep it charged at the proper float level.
4. Battery-serves as the backup energy source or the critical load
5. DC-AC inverter converts the DC battery voltage into an AC output voltage
6. Voltage Transformer-Boost and isolates the AC voltage produced by
    the DC-Ac inverter.
7. Transfer Switch - Select which power will supply the load at a given time.
8. Microprocessor - Controls all critical functions of the UPS.
9. Smart line conditioner provides voltage regulation to the load with using battery
    power.

1. What type of UPS do you need?

When shopping for a UPS, there are 3 main types of UPS you are likely to encounter:

 1. On-Line
 2. Standby ( Also called Off-Line)
 3. Line-Interactive
 

Standby (Off-Line) UPS

This is the topology used by the PCM WOW UPS Series, E-Book UPS Series and Compact UPS Series. The AC line is the primary power source. The battery / Inverter circuitry supplies the load in case of a power failure for fluctuation. Any drop in the voltage or current is detected by the UPS, which automatically switches the battery into the circuit, cutting of the main power line thus allowing the battery to supply the required power. The transfer time should not take more than 4 milliseconds, as this is the tolerance limited of a typical computer power unit.

Line-Interactive UPS

This is the topology used the PCM Black Knight (Pro) Series, Imperial Series, King Series, and Smart King Series. The AC line power is the primary source and is being constantly filtered. In case of a brownout condition, the AVR (Automatic Voltage Regulator) circuitry is activated to correct the problem. The battery and inverter circuitry supplies the backup power is in case of blackout.
