350 WATT DC/DC POWER SUPPLY Product Data Sheet DNX350 FEATURES Fully Isolated Outputs Low Profile: 9” x 4.85” x 2.00” One, Two, Three and Four Output Models Active Current Sharing on V1 Optional Fan Covers (Top-Mounted or End-Mounted) Active Inrush Current Limiting 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 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.
