Optional protections

Ø  Blower thermal overload protection: alarm & remove load

Ø  Short circuit protection by fuse(over current protection)

Ø  Phase sequence protection(for fans with 3phase voltage)

Ø  Or other functions as requested

FORESIGHT series load bank control modes

Two control modes available for FORESIGHT series AC/DC load banks: The local panel control mode and the PC software remote control mode.

Local panel control mode available as below listed:

Ø  By contactor

Ø  By circuit breaker

Ø  Or other switches as requested

PC software remote control(optional)

FORESIGHT series AC/DC load bank remote control communication protocol would be provided for clients’ integrating the load bank into the ATE system
