Top Microsystems 550W 7 Output ATX Power Supply P6550E FE2 This is a Brand New Top Microsystems 550W 7 Output ATX Power Supply P6550E FE2. Switching Power Supply 16 Outputs! 3.3V +/-5V +/- 12V @ 1 to 60A 523W. There is no shortage of connectivity with this power supply. The connectors are for the following outputs--seven channels in all--from 120V AC in: 550 Watts 7 Output ATX, EPS12 Industrial Grade Power Supply With Active PFC (Extended PS/2 type) Input Current 10Amps – 5Amp Input Voltage 100 to 240 VAC Input Frequency 47 Hz to 63 Hz Input Waveform The unit is capable of operating with a 10% distorted sine wave input as measured by a distortion analyzer. Its flattopping clipped 10% from the peak value of standard sine wave. A remote +3.3VDC sense line connector allow for accurate control of the +3.3VDC line directly at load. Due to potential voltage drops across the connector and traces leading to the PCB components, it may be advantageous to implement a +3.3V sense line that remotely monitors the +3.3VDC power level at the load. PS-ON is an active low signal that turns on all of the main power rails including +3.3V, +5V, +12V & -12V , -5V power rails. When this signal is held by the PC board or left open circuited, outputs of the power rails should not deliver current and should be held at a zero potential with respect to ground. Power should only be delivered to the rails if PS-ON signal is held at ground potential. This signal should be held at +5VDC by a pull-up resistor internal to the power supply. Over Power Protection The power supply shall shut down all DC outputs when outputs power are overloaded to 110~150%+3.3V at 30A, +5V at 40A, +5VSB at 2A, -5V at 1A, +12V1 at 18A, 12V2 at 18A,and -12V at 1A.
