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: 115% of nominal voltage is typical. The power supply will latch off until AC power is cycled. Over Current Protection Automatic recovery upon fault removal. Transient Response The peak output voltage excursion will not exceed 2% and will recover within 1% in 200 sec for a 25% step load. Reverse Voltage Protection The output is protected to rated load. Power Fail Signal Upon AC input voltage removal, the power fail signal drops to logic zero at least 10msec before loss of DC output. Upon AC input turn-on, signal remains low until output is in regulation. Consult the factory for other options. N+1 Load Share Output has active load sharing circuitry. Units will load share within 1% of the Maximum Rated Load. Over Temperature Protection Thermal switch turns off power supply if overheating occurs and automatically restarts. Safety UL/CUL Recognized: UL File Number E13164 (1950) TUV License Number: R9773309 (EN60950) (IEC950) Cooling The unit is designed to operate with 30 CFM of airflow. DC Power Good Signal The signal is activated by a 10% loss of regulation Active low or high; TTL Level; common with (-) sense. Consult the factory for other options.
