P81/500E Series AC/DC Power Supplies for Information Technology Equipment (ITE)
P81/500E Series 500-watt ITE AC/DC power supplies come in three versions: 12V C, 41.5A output (P81/500E-12S); 24V DC, 20.8A output (P81/500E-24S) and 48V DC, 10.41A output (P81/500E-48S). They accept a wide, universal 90-264V AC, 47-63 Hz input range, and they come in a 5.12 x 3.27 x 2.45-inch package. The supplies feature an active PFC function, high efficiency up to 91.5%, 4,000V AC I/O isolation, up to 5,000m altitude operation and a wide operating temperature range of -30 to +70°C with derating. Standby power is 5V at 1A, and the no-load power consumption is <0.3W.
