Power Supply MPM-925C 250W PS/2 Power Supply 2.0 Specifications DC OUTPUT WIRES * Input Voltage: 90~264VAC 37.0 * Input Frequency: 47~63Hz 0.35 * Inrush Current: The maximum inrush current will not exceed 30A at 115VAC or 60A at 0.42 0.4 o 230VAC input, cold start, 25 C * Load Range: At factory, all outputs at 60% rated load condition; the +5V output is set to 2.0 11.0 between 4.9~5.1V. The other outputs are checked to be within the specified voltage accuracy range * Ripple And Noise: The peak to peak ripple and noise for each outupt is less than 1% of each output voltage at rated load, 115/230VAC. Measuring is done by 15MHz bandwidth 14.4 limited oscilloscope and terminated each output with a 47uF capacitor 14.0 * Line Regulation: The line regulation for +12V is less than +/-2%, for other output is less than +/-1% while measuring at rated load and +/-10% of nominal line input voltage changing * Load Regulation: The output voltage load regulation is less than the values in the following table by changing each output loading +/-40% from 60% rated load, and keep all other outputs at 60% rated load * Hold Up Time: Hold up time is 14ms typical by measuring from the last AC line charging 15.0 pulse to the point that +5V drop down to +4.75V at rated load 0.5 13.8 * Output Power: The total DC continuous power shall be kept within 200W * Power Good Signal: When power start up, the power good signal will increase 100~500ms after all output DC voltages are within regulation limits * Power Failure Signal: The power fail signal will fall at least 1ms before any of the output 6.4 8.62 voltages lower than the regulation limits 3.72 * Efficiency: The efficiency is 65% typical by measuring at nominal line, and full rated load 2.7 * Protection: For some reason the power supply fails to control itself, the build-in over 2.4 1.6 voltage protection circuit will shut down the outputs to prevent damaging external circuits. 0.1 0.6 The trip point of crwobar circuit is around 5.7~7V. The power supply will go into hiccup 4.8 0.5 mode against short circuit or over load conditions, and will auto-recovery while faulty 11.5 conditions are removed o o * Temperature: 0~40 C (operating); -40~+75 C (storage) * Connectors: AC Input: Meets IEC 320/CEE 22 standard DC Output: Meet IEC 320 (reverse type) CPU Board: Burndy GTC 6P-1 or equivalent Output Min. Rated Peak Voltage Voltage Load Load Load Accuracy Disk Driver: AMP 1-480424-0 or equivalent +5V 4A 22A 28A 4.9~5.1V 3.5" Floppy Drive: AMP 171822-4 or equivalent +12V 1A 7A 10A 11.28~12.72V AC Switch: Push switch (lever: 20mm) -12V 0A 0.5A 1A -11.4~-12.6V * Dimensions: 15.0 x 14.0 x 8.62 cm. Tolerance specified is +/-0.4mm between mounting -5V 0A 0.5A 1A -4.75~-5.25V holes and +/-0.8mm for other dimensions Safety Standards * Safety: UL 544, UL 2601-1, CSA 22.2 No.601, TUV (DIN VDE 075T, 1/12.91/EN 60 601-1:1990) * GND Leakage Current: It should be less 500uA at 244VAC input * EMI: EN 55011 class "B" * Immunity: IEC-801-2 4KV, contact, 8KV air discharge / IEC-801-3 3V/M, 26MHz to 1GH / IEC- 801-4 2KV power mains
