PROTECTION
Output Over-Voltage: Shutdown at 396V Output Voltage, Recycle of
input voltage required to reset OVP circuit.
Output Over current/Short Circuit Protection: Electronic with automatic recovery
Output Over power protection: 300W
Over-Temperature: Over temperature shutdown with auto recovery
Input Over-Current: AC fused internally. For failure modes only.
ELECTRONIC ALARMS
AC OK: low when AC input is in range
Output OK: low if the output voltage is within 240VDC and 395VDC
(low=<.6V@1mA) (high=open collector (I<50µA)
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)
Remote Program: With 0 to 10VDC control signal, Output voltage
changes linear governed by the formula VOUT(VPROG)=mVPROG+207.3 ;
where m=22 +/- 1%. Remote program must be referenced to Output
