Local ON/OFF control (AC breaker)
The AC input circuit breaker can be used to locally turn the rectifier ON/OFF. The local ON/OFF control overrides remote control signals.
Remote ON/OFF control
When a battery return (BAT RTN) signal is applied to the 'Temporary Release' (TR) input, the rectifier inhibits its operation ( no RFA will be transmitted). Upon removal of the remote ground signal the rectifier returns to normal operation.
Remote voltage sensing
Provision is made to extend the sensing leads to the battery or to the charge / discharge bus (batteryless operation) of the plant. Opening either sense lead will not adversely affect the rectifier output voltage and the rectifier will default to internal sensing mode.
Sense fail alarm (SEN FAIL)
In the event that the remote sense leads are not connected or reversed, the RC fuse on the controller fails, or the DC circuit breaker is opened. An alarm will be transmitted through the signal connector only.
Current limiting
The rectifier will limit the output current to 30 A + 0.5 A (factory setting). The current limit level can be adjusted between 12.5 A to 30 A at 54.5 V DC, or to any combination limited to 1635 W of output power within the adjustable voltage range. Extended periods of operation in the current limiting mode and repeated transitions between
