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 (Optional)
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.
Over Voltage Protection
Output #1: 6.5V ± 0.5 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.
Active Inrush Current Limiting
Inrush current is independent of ambient temperature.
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.
Over Temperature Protection
Thermal switch turns off power supply if overheating occurs
and automatically restarts.
Safety
Safety Certified to UL/CUL to 1950, File Number E131694.
TUV to EN60950/IEC 950.
Cooling
The unit is designed to operate with 30 CFM of airflow.
