Remote Sense
Remote Sense is provided on Output #1 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: 6.5V ± 0.5 VDC.
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.
Transient Response
The peak output voltage excursion will not exceed 2% and
will recover within 1% in 200 μsec for a 25% load step
change.
Power Fail Signal
Upon AC input voltage removal, the power fail signal drops
to logic zero at least 5msec before loss of DC output. On
AC input turn-on, signal remains low until outputs are in
regulation. Consult the factory for other options.
N + 1 Load Share
Output #1 has active load sharing circuitry. Units will load
share within 1.5% of Maximum Rated Load.
Over Temperature Protection
Thermal switch turns off power supply if overheating occurs
and automatically restarts.
