PWI 100-P99L Series • Fully encapsulated • Conduction cooling • Full electronic protection • Universal input range • Rugged, field proven design This fully encapsulated, rugged, industrial quality AC-DC power supply uses field-proven technology to generate the required output power. It has an excellent track record in numerous heavy-duty applications. The unit is entirely potted with a thermally conductive MIL-grade silicon rubber compound to increase resistance to shock, vibration and humidity. Cooling is via base plate by conduction. The unit is designed for continuous operation at 70oC with installation on an appropriate heatsinking surface. Full electronic protection, low component count, large design headroom, and the use of components with established reliability ensure high MTBF. The unit is suitable for transportation, mining, oilrigs, military and other harsh environments. It is manufactured at our plant under strict quality control. Versions that are designed to meet EN 50155 railway specifications are also available. Universal input 95Vac - 264Vac, 47-63Hz DC-input also available Consult factory for other voltages Inrush current limiting Varistor Internal safety fuse Line to GND varistor upon request Lower voltage than the specified minimum input will not damage the unit 2250Vdc input to chassis 4300Vdc input to output 8mm spacing 500Vdc output to chassis Designed to meet EN 62368-1 and corresponding UL and CSA standards EN 55032 Class A with margins Minimum 5ms at full load for 5% drop of output voltage at 120V AC input. 12Vdc/8A, 24Vdc/4A or 48Vdc/2A Output is floating, either terminal can be grounded Consult factory for other voltages ±1% combined from zero load to full load Dynamic Response Max 5% voltage deviation for 10% to 50% load step, with better than 1msec recovery time Output Ripple/Noise Better than 1% of output voltage peak to peak or 0.2% RMS of the output voltage. (20MHz BW) Rectangular current limiting with short-circuit protection (hiccup type) Double regulator loop completely stable and independent of main regulator loop Output is voltage dependent. Typically 80% at full load -40oC to +70oC cold-plate temperature for full specification Temperature Drift 0.03% per °C over operating temperature range. Conduction via base plate to customer heatsink or chassis Full encapsulation with thermally conductive silicon potting compound with UL94V-0 flammability rating.
