Power Supply MPD-830R 300W DC/DC ATX Power Supply Specifications * Input Voltage: The range of input voltage is from 72~136VDC * Input Current: The maximum input current is 5A at 110VDC input o * Inrush Current: The inrush current will not exceed 10A at 110VDC input cold start, 25 C * Load Range: At factory, all outputs in 60% rated load condition; the +5V output is set to between 4.80V and 5.20V. The other outputs are checked to be within the specified voltage accuracy range * Ripple And Noise: The peak to peak ripple and noise for +5V, +3.3V outputs are less than 50mV, and for the other output are less than 100mV at rated load. Measuring is done by 15MHz bandwidth limited oscilloscope and terminated each output with a 0.47uF capacitor electrolysis capacitor at rated load, nominal line DC INPUT CABLE * Line Regulation: The output line regulation for each output is less than +/-1% while measuring at rated load and -40~-72VDC input voltage changing DC OUTPUT WIRES * Load Regulation: The output voltage load regulation is less than the values in the following 30.0 0.3 3.0 table by changing each output load +/-40% from 60% from rated load, and keep other 0.3 0.4 outputs at 60% rated load 1.08 * Output Power: The total DC continuous power shall be kept within 300W ambient 0.5 o temperature of 40 C below, and input voltage at 110VDC. The maximum, total combined 1.5 12.0 1.5 output power on the 3.3V and 5V rails is 150W * Power On Signal: This TTL compatible signal (active low) is use to switch ON the main output. When power on is disconnected from secondary common, all outputs except +5Vsb shall turn off * Power Good Signal: When power start-up, the power good signal will increase between 13.0 100ms to 500ms after all output DC voltages are within regulation limits * Power Fail Signal: The power fail signal will fall at least 1ms before any of the output voltages lower than the regulation limits * Efficiency: The efficiency is higher than 65% while measuring at nominal line and rated output * Altitude: Will operate properly at any altitude between 0 to 10000ft * Protection: 0.5 Over Voltage: For some reasons the power supply might fail to control itself, the build-in 1.0 12.5 1.5 crowbar circuit will automatically shut down the outputs to avoid damaging the external 0.47 13.8 circuits. The trip point of O.V.P. circuit is around 5.7V to 7.0V Short Circuit: The power supply will go into hiccup mode function against short circuit or over load conditions. If the faults condition removed, the power supply will restart automatically o o o o * Temperature: 0~70 C, -20 C can start up, derating from 50 C (operating); -40~+75 C 6.4 (storage) 8.62 8.0 * Humidity: The power supply can operate from 5% humidity to 95% humidity non-condensing o at 40 C 4.29 * Connectors: 1.6 DC Connectors: 3 positions terminal blocks 0.6 ATX: Molex 39-01-2200 or equivalent 5.23 0.5 11.4 3.1 Disk Drive: AMP 1-480424-0 or equivalent 15.0 3.5" Floppy Driver: AMP 171822-4 or equivalent P4: Molex 39-01-2045 or equivalent * Dimensions: 14.0 x 15.0 x 8.62 cm; Tolerance specified is +/-0.4mm between mounting Output Min.
