PULS Power: PISA-B Multi-Channel Electronic Circuit Breaker

PISA-B is an efficient electronic circuit breaker (ECB). It distributes the current, protects your loads from over-current or short-circuits and monitors the operating status in DC 24V systems. The 8-channel programmable capability can identify and isolate individual faulty branches. It shuts down the affected channels only and secures the constant power supply of the remaining loads. An integrated data monitoring reports the operating status to a PLC or control center. The electronic circuit breaker also alarms in case of an error and allows a remote reset of the channels.
