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.
