DESCRIPTION
36-72VDC Input
The DNX350 is a compact 350 watt, multiple output power supply
that operates from a 36-72VDC source. All outputs are fully
isolated and regulated. Active current sharing circuitry on Output
#1, together with control functions and alarm options, simplifies
N+1 and redundant applications. Fan and disk drive applications
are handled by the peak current ratings of the auxiliary outputs.

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.
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.
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 Temperature Protection
Thermal switch turns off power supply if overheating occurs
and automatically restarts.
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.
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.
Active Inrush Current Limiting
Inrush current is independent of ambient temperature.
