Remote Sense
Remote Sense is provided on all outputs and will
compensate for 0.7V of line drop. Remote Sense leads
are protected against open, short, and reversal.
Remote On/Off
The power supply is turned on with a TTL logic ‘1’ (or open)
signal and turned off by a switch closure or TTL logic ‘0’
referenced to (-) sense terminal. Consult the factory for
other options.
Over Voltage Protection
Output #1: 6.25V, ±0.8 V
DC
.
The power supply will latch off until AC power is cycled.
Over Current Protection
Individual current limit on all outputs. Automatic recovery
upon fault removal.
Reverse Voltage Protection
All outputs are protected to rated load.
Transient Response
The peak output voltage excursion on the main output will
not exceed 2% and will recover within 1% in 200
μ
Sec for a
25% load step change.
Output Isolation
All outputs are fully isolated.
Power Fail Signal
Upon AC input voltage removal, the power fail signal drops
to logic zero at least 5msec before loss of DC output. Upon
AC input turn-on, signal remains low until outputs are in
regulation referenced to (-) sense terminal. Consult the
factory for other options.
DC Power Good Signal
Upon a ±10% loss of regulation on any output, the DC
Good signal drops to a logic zero referenced to (-) sense
terminal. Consult the factory for other options.
Over Temperature Protection
Internal thermal switch turns off power supply if overheating
occurs and automatically restarts when temperature drops
below threshold.
