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 Input frequency
The range of input frequency is from 47Hz to 63Hz.
2.3 Input current
The maximum input current is 1A at 115V AC or 0.6A at 230VAC.
2.4 Inrush current
The inrush current will not exceed 20A at 115VAC input or 40A at 230VAC input, cold start,
25℃.

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 0.47µF capacitor.
3.3 Line regulation
The line regulation is less than +/-1% when measuring at rated load and +/-10% of input
voltage changing.
3.4 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.
