Detailed data
ABB SS822 3BSC610042R1 Power Voting Unit
The Voting Units SS822Z, SS823 and SS832 have been specifically designed to be employed as a control unitwithin a redundant power supply configuration. The output connections fromtwo 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 thatthe correct outputvoltage is being delivered. Simultaneously with the green LED illuminating, a voltage free contact closes the path to the corresponding “OK connector”. Voting Unittrip levels, are factory preset.
