Output Isolation
All outputs are fully isolated.
Remote Sense
Remote Sense is provided on Output #1 and will
compensate for 0.3V of line drop. Remote Sense leads
are protected against open, short, and reversal.
Power Fail Signal
Upon AC input voltage removal, the power fail signal drops
to logic level ‘0’ at least 5msec before loss of DC output.
Upon AC input turn-on, signal remains low until outputs are
in regulation. Consult the factory for other options.
Remote On/Off
The power supply is turned on with aTTL logic level‘1’(or
open) signal and turned off by a switch closure orTTL logic
level‘0’referenced to (-) sense terminal.Consult the factory
for other options.
DC Power Good Signal
The signal drops to logic level‘0’by a 10% loss of regulation
on any output, common with Output #1 (-) sense. Consult
the factory for other options.
Over Voltage Protection
Output #1: 6.25V, 0.75 VDC.
Over Temperature Protection
Output #2: 14.0V 1VDC. (Output #2 12V)
17.0V 1VDC. (Output #2 15V)
The power supply will latch off until AC power is cycled.
Internal thermal switch turns off power supply if overheating
occurs and automatically restarts. Automatic restart when
temperature drops below threshold.
Over Current Protection
Individual current limit on all outputs. Automatic recovery
Safety
UL Recognized: UL File Number 14675 (1950 & 1012)
CSA Certified: CSA File Number LR9070-154C
(C22.2 No. 234-M90, Level 6)
upon fault removal.
Reverse Voltage Protection
All outputs are protected to rated load.
TUV License Number:R9576025 (EN60950) (IEC950)
Transient Response
Cooling
The peak output voltage excursion on the main output will
not exceed 2% and will recover within 1% in 50 mSec for a
25% load step change. On outputs #2-5, the peak output
voltage excursion will not exceed 1% for a 25% load step
change.
The unit is designed to operate with 30 CFM of airflow.
