Power Fail Signal
Remote Sense
Upon AC input voltage removal, the power fail signal drops
to logic zero at least 10msec before loss of DC output.
Upon AC input turn-on, signal remains low until output is in
regulation. Consult the factory for other options.
Remote Sense is provided and will compensate for 1.0V
of line drop. Remote Sense leads are protected against
open, short and reversal.
Remote On/Off (Optional)
N+1 Load Share
Output has active load sharing circuitry. Units will load
share within 1% of the Maximum Rated Load.
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.
Over Temperature Protection
Thermal switch turns off power supply if overheating occurs
and automatically restarts.
Over Voltage Protection
Output #1: 15% of nominal voltage is typical.
The power supply will latch off until AC power is cycled.
Safety
UL Recognized: UL File Number E13164 (1950)
CSA Certified: CSA File Number LR 9070C
(C22.2 No950, Level 6)
Over Current Protection
Automatic recovery upon fault removal.
TUV License Number: R9773309 (EN60950) (IEC950)
Transient Response
The peak output voltage excursion will not exceed 2% and
will recover within 1% in 200 µsec for a 25% step load.
Cooling
The unit is designed to operate with 30 CFM of airflow.
Reverse Voltage Protection
DC Power Good Signal
The output is protected to rated load.
The signal is activated by a ±10% loss of regulation Active
low or high;TTL Level; common with (-) sense. Consult the
factory for other options.
