P81/240E Series 240-Watt AC/DC Power Supplies for Information Technology Equipment (ITE)
P81/240E Series ITE power supplies accept a wide, universal 90-264V AC, 47-63 Hz input range and meet the new edition OVC III overvoltage standard for fixed-installation applications. Three versions are available, depending on output and cooling. The units come in a 4.1 x 2.46 x 1.54-inch package, and they feature an active PFC function, high efficiency up to 94%, 4,250V AC I/O isolation, up to 5,000m altitude operation and a wide operating temperature range of -40 to +80°C with derating. No-load power consumption is <0.5W.
