| MPE-902M Specification 902M-031703 SPECIFICATION For SWITCHING POWER SUPPLY M/N: MPE-902M Proprietary Information Magic Power Technology Co., Ltd. 1 MPE-902M Specification 902M-031703 1.0 INTRODUCTIONS MPE-902M is 20Watts, universal AC input switching power supply. This model has over-voltage crowbar protection in main output. 2.0 INPUT SPECIFICATIONS 2.1 Input Voltage The range of input voltage is from 85VAC to 260VAC. 2.2 2.3 2.4 Input frequency The range of input frequency is from 47Hz to 63Hz. Input current The maximum input current is 1A at 115V AC or 0.6A at 230VAC. Inrush current The inrush current will not exceed 20A at 115VAC input or 40A at 230VAC input, cold start, 25. 3.0 OUTPUT SPECIFICATIONS 3.1 Load range Output voltage Min. load Rated load Peak load Voltage accuracy +5V 0A 1.5A 2.5A 4.95V to 5.05V +12V 0A 1A 1.5A 11.4V to 12.6V At factory, both outputs in 60% rated load condition; the +5V output is set to between 4.95V and 5.05V, and +12V is checked to be within the specified voltage accuracy range. 3.2 Ripple and noise The peak to peak ripple and noise is less than +/-1% of output voltage at rated load. Measuring is done by 15MHz bandwidth limited oscilloscope and terminated the output with a 0.47F capacitor. Line regulation The line regulation is less than +/-1% when measuring at rated load and +/-10% of input voltage changing. Load regulation The load regulation for +5V is less than +/-1%, for +12V is less than +/-4%, measuring is done by changing the output load +/-40% from 60% rated load, and keep the other output at 60% rated load. 3.3 3.4 Proprietary Information Magic Power Technology Co., Ltd. 2 MPE-902M Specification 902M-031703 4.0 GENERAL FEATURES 4.1 Efficiency The efficiency is 75% typical while measuring at nominal line and rated load. 4.2 Hold up time The hold up time is longer than 16mS at 115VAC input and rated load. 4.3 Protection For some reasons the power supply might fail to control itself, the build-in over voltage protection circuit will shut down the outputs to prevent damaging external circuits. The trip point of crowbar circuit is around 5.7V to 6.7V. The power supply will go into hiccup mode against short circuit or over load conditions, and will auto-recovery while faulty conditions are removed. 5.0 ENVIRONMENT SPECIFICATIONS 5.1 Operating temperature 0 to 50 5.2 Storage temperature -20 to 85 5.3 Altitude Will operate properly at any altitude between 0 to 10000 ft. 6.0 INTERNATIONAL STANDARDS 6.1 Safety standards Designed to meet the following standards: UL 1950 D3 CSA 22.2 No.234 EN 60950 6.2 EMI standards Designed to meet the following conducted limits: FCC docket 20780 curve "B" Proprietary Information Magic Power Technology Co., Ltd. 3 MPE-902M Specification 902M-031703 7.0 MECHANICAL SPECIFICATION 7.1 Dimensions Dimensions are shown in mm (inch) as above. Tolerance specified is +/-0.4mm. 7.2 Connectors TB1--AC input TB2--DC output : : Molex 5277-2 or equivalent. AMP 1-480424-0 or equivalent. 7.3 Wire color vs. output voltage Yellow - +12V Red - +5V Black - GND Proprietary Information Magic Power Technology Co., Ltd. 4 |
