voter (ووتر و محافظ ولتاژ) – ABB، مدل SS832، کد فنی 3BSC610068R1

The Voting Units SS822Z, SS823 and SS832 have been specifically designed to be employed as a control unit within a redundant power supply configuration. The output connections from two Power Supply Units are connected to the Voting Unit.

The Voting Unit separates the redundant Power Supply Units, supervises the voltage supplied, and generates supervision signals to be connected to the power consumer.

Green LED’s, mounted on the front panel of the voting unit, provide a visual indication that the correct output voltage is being delivered. Simultaneously with the green LED illuminating, a voltage free contact closes the path to the corresponding “OK connector”. Voting Unit trip levels, are factory preset. Simple DIN-rail mounting
Class I Equipment, (when connected to Protective Earth, (PE))
Over-voltage Category III for connection to primary main
TN network
Protective separation of secondary circuit from primary circuit
Accepted for SELV and PELV applications
The output of the units is protected against over current
(current limit) and over voltage (OVP)
