Power Fail Signal
Remote Sense
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.
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 aTTL 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.
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 Voltage Protection
Output #1: 6.25V, 0.8 VDC.
The power supply will latch off until AC power is cycled.
Over Temperature Protection
Internal thermal switch turns off power supply if overheating
occurs and automatically restarts when temperature drops
below threshold.
Over Current Protection
Individual current limit on all outputs. Automatic recovery
upon fault removal.
Safety
UL Recognized:UL File Number 14675 (1950 & 1012)
CSA Certified: CSA File Number LR9070-154C
(C22.2 No. 234-M90, Level 6)
Reverse Voltage Protection
All outputs are protected to rated load.
TUV License Number:R9576032 (EN60950) (IEC950)
Transient Response
Cooling
The peak output voltage excursion on the main output will
not exceed 2% and will recover within 1% in 200 µSec for a
25% load step change.
The unit is designed to operate with 30 CFM of airflow.
Output Isolation
All outputs are fully isolated.
