What do I gain with a Unity Output Power Factor (kW=kVA)?

Published date: 24 January 2018

 
Issue:
What do I gain with a Unity Output Power Factor (kW=kVA)?
 
 
Product line:
Three Phase UPS Systems
 
 
Environment:
All models/ all serial numbers
 
 
Cause:
What do I gain with a Unity Output Power Factor (kW=kVA)? The advantage of unity power factor is that these UPS systems are 100% compatible with today's high power factor loads. Traditionally, a UPS with a lower power factor needs to be oversized to support today's power factor corrected loads.  Some APC 3-phase UPS products as well as newer single phase products(SRT6K) have an output rating of kW=kVA or Unity Power Factor. While the more traditional double conversion units have output ratings of kW=0.8kVA.
