PROTECTION
Output Over-Voltage: Output hiccup on over-voltage
Output Over Current/Short Circuit Protection: The converter
becomes a current source in overload conditions. After 5 sec in
short circuit output will hiccup @T= 60 sec, 10%D.
Output Over Power Protection: Electronic, set to 4,100W
Over-Temperature: Over temperature shutdown with auto
recovery
Input Over-Current: 20A fused for failure modes only.
COMMUNICATION
Communication Protocol: J1939 CAN BUS. (Optional)
CAN BUS SIGNALS:
DC IN OK
Output OK
Output Current Monitor
Output Voltage
ELECTRONIC CONTROL INPUTS
Remote Inhibit: Application of a 3.3V input signal will cause the
supply to shut down and an output OK fault alarm will be issued.
(3.3V = Inhibit)
