DALTON UPS B33 SERIES

B33 Online Double Conversion UPS
 Three Phase/Three Phase
10kVA – 60kVA

This online plus series is an uninterruptible power supply
 incorporating double-converter technology.
It provides perfect protection specifically for critical load. 
The double-converter principle eliminates all mains power disturbances. 
A rectifier converts the alternating current from the socket outlet to direct current. 
This direct current charges the batteries and powers the inverter. 
– Out Unity power factor 1.0
– DSP Technology touch screen
– Active input power factor correction 
– Support the generator
– Zero power switch delay
– Adaptive Load Management
– Fully protected
