DALTON UPS b33 SERIES

B33 Plus Smart Online Double Conversion UPS
Three Phase 3:3 Dalton B33 Plus
10KVA – 80KVA

The On-Line- B31 Series is an uninterruptible power supply incorporating 

double-converter technology. IT , Medical  provides perfect protection specifically for strict load. 

The double-converter principle eliminates all mains power disturbances. 

In the event of power failure, the maintenance-free batteries power the inverter. 

Designed with high protections 

UPS offers the greatest degree of availability in power protection and provides 

continuous high-quality AC power to connect strict load,

 
-Online true double conversion ups
-Output Short Circuit and Overload Protection
– Cold Start Function
– Optional SNMP Communication Port
– Maintenance Bypass Switch
