ACB protection

 

Description

ACB protection is designed to protect accumulator battery (ACB) against the short-circuit currents in the DC circuit (including cases of deep discharge of ACB). Protection is ensured by breaking the DC circuit if the current in it exceeds the permissible level. It is installed at 19 " rack.



Application area

Systems of uninterruptible power supply, where batteries are used as a redundant power supply; in DC systems; in operating DC supply systems.



Functions

- power shifting;

- Manual emergency shutdown;

- status control of fuses¹.

1 is installed optional
