I Ntroduction - FSP Technology EP 1000 Series Specification

1 I ntroduction

EP series is a line interactive power system that has a step wave output. It prevents impulse,
surge, sag and power outage situations. It provides the UPS output load with a reliable
source. It has the following functions:
1.1 Boost:
If the utility voltage drops to line boost activated point*, the AVR will be activated
and increase the input voltage by 1.18 times of incoming utility voltage.
* Boost activated point
110 VAC
99 VAC
1.2 Buck:
If the utility voltage reaches to line buck activated point, the AVR will be activated
and decrease the input voltage by 0.85 times of incoming utility voltage.
* Buck activated point
110 VAC
121 VAC
1.3 50/ 60Hz Automatic Frequency Selection:
The output frequency will automatically match the input frequency (50 or 60Hz).
1.4 Communication Port ( USB) :
It provides remote shutdown capability via communication port for connected
computers.
1.5 Data line/ telephone line protection:
The unit provides RJ11 port to provide transient voltage surge suppression
(TVSS) for data line or telephone line.
1.6 Cold start ( DC start) :
The UPS is equipped with DC start function to turn on the UPS without input source.
