(-C) (-CF) (CEF) 2:1 wide ratio 5 V @ 100 mA regulated; 12V @ 500 mA 20 ms @ 250 W load, 115 VAC nominal line at factory voltage setting Short circuit protection on all outputs. Case overload protected @ 110-145% above peak rating 5 V output: 5.7 to 6.7 VDC. Other models 10% to 25% above nominal output Logic Control Power failure Remote on/off Operating temperature: 0° to 50°C ambient derate each output at 2.5% per degree from 50° to 70°C Electromagnetic susceptibility: Designed to meet IEC 801, -2, -3, -4, -5, -6, Level 3 Remote sense Humidity: Operating; non-condensing 5% to 95% TTL logic signal goes high 50-150 msec after 5 V output. It goes low at least 4 msec before loss of regulation Requires an external contact (N.O or N.C) to inhibit outputs TTL logic goes high 50-150 msec after the output. It goes low when there is loss of regulation. Compensates for 0.5 V lead drop min. Will operate without remote sense connected. Reverse connection protected. Vibration: Three orthogonal axes, sweep at 1 oct/min, 5 min. dwell at four major resonances 0.7 G peak 5 Hz to 500 Hz, operational Storage temperature: -40° to 85°C Temperature coefficient: ±.04% per °C MTBF demonstrated: >550,000 hours at full load and 25°C ambient conditionsation
