300 WATT ATX SWITCHING POWER SUPPLY WITH PFC PCB300ATXE-F-W GENERAL SPECIFICATION This specification describes the performance characteristics of a grounded, single phase, 300 watts, 6 output level power supply with ATX Form Factor remote control, +3.3V, +5V, +12V, -5V, -12V and +5Vsb. In addition, it meet a worldwide safety requirement and electromagnetic compatibility requirement for ATX power supply with PFC (Power Factor Correction). 1) INPUT Description Min. Nominal Max. Condition Input Voltage 90 VAC ---264 VAC Full Range VOLTAGE SELECTION Full Range Function. 6 Amps maximum at 115 VAC input voltage Input Current (RMS) 3 Amps maximum at 230 VAC input voltage Frequency 47Hz 50/60Hz 63Hz SINGLE PHASE 30 Amps peak max. For one half cycle of AC 115V (cold start) Inrush Current 60 Amps peak max. For one half cycle of AC 230V (cold start) The power supply efficiency should not be less than 65% at the Maximum Efficiency load with the AC input at any nominal low range of high range voltage. >0.97 at Low Input Voltage (Nominal 110VAC) POWER FACTOR(WITH PFC) >0.92 at High Input Voltage (Nominal 230VAC) 2) OUTPUT 2.1) STATIC DC LOAD NOMINAL VOLTAGE(DC) LOAD MIN. CURRENT MAX. PEAK CURRENT REGULATION (%) +3.3V 0.3A 28A +/-5 +5V 2A 30A +/-5 -5V 0A 0.3A +/-5 +12V 1A 15A 20A +/-5 -12V 0.05A 0.8A +/-10 +5Vsb 0.05A 2.5A 2.5A +/-5 NOTE: The total output of 3.3V & 5V should not exceed 180 watts and the total output should be 300 watts the max. When +5V at min. load, +12V can not sink over 7A. ETA-USA Tel: 408-778-2793 Fax: 408-779-2753 e-mail: sales eta-usa.com 2.2) REMOTE ON/OFF CONTROL As logic level is LOW: Output voltage is enabled. As logic level is HIGH or floating: Output voltage is disabled. Note: Logic high level: >4.0V Logic low level:<0.8V 2.3) AC OUTPUT CONNECTOR (Optional) Minimum---Maximum Maximum Output Current Full Range 90 VAC ---264 VAC 2Amps 2.4) RIPPLE AND NOISE The ripple and noise of the outputs should be measured at the full load Output Voltage(DC) Ripple & Noise(p-p) +3.3V 50mV +5V 50mV -5V 50mV +12V 120mV -12V 120mV +5Vsb 50mV NOTE: 20MHz bandwidth ripple & noise is measured by using 0.1uF C.C. & 47uF/50V E.C. bypassed at the output connector. 2.5) HOLD UP TIME The power supply unit should maintain its proper output voltage within voltage specifications for at least 20 milliseconds after losing input power under the condition of 100 VAC (or 230 VAC input) with full loading. 2.6) OPERATION AT NO LOAD The power supply shall be capable of being operated with no load on any or all outputs without damage. For no load on +3.3V & +5V, the output shall not Exceed +4.5 & +6.5VDC and the power supply may shutdown and require by Remote-control or remove AC power restart. 3) OVERSHOOT Any overshoots during turning-on or turning-off should be less than +/-5% of the nominal output voltage values. All outputs shall fail within the regulation limit of paragraph 3.1 before the power good signal is issued. 4) TEMPRATURE COEFICIENT The temperature coefficient of all outputs is +/-0.05% per degree C maximum. 5) PROTECTION: 5.1) OVER VOLTAGE PROTECTION: If any over voltage occurs, the power supply should latch off before any output exceeds its limit below: OVERVOLTAGE RANGE (V) NOMINAL VOLTAGE (V) FROM TO +3.3 4.0 4.5 +5 5.6 6.5 +12 13.5 15.5 The power supply will not be automatically recovered after the over voltage fault being removed. A manual power reset is necessary. ETA-USA Tel: 408-778-2793 Fax: 408-779-2753 e-mail: sales eta-usa.com
