| Contact Factory for Replacement Model Input Specifications Parameter Operating Range Inrush Current Limiting 36VD 72VDC Efficiency 48 VDC, at full load 70 25 50 APK APK % Conditions DC Min 36 Typ 48 Max 72 Units VDC 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. Consult the factory for other options. 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. 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 sec 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/IEC950. Cooling The unit is designed to operate with 30 CFM of airflow.
