MPE-902M Specification
The range of input frequency is from 47Hz to 63Hz.
The maximum input current is 1A at 115V AC or 0.6A at 230VAC.
The inrush current will not exceed 20A at 115VAC input or 40A at 230VAC input, cold start,
25℃.
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.
The line regulation is less than +/-1% when measuring at rated load and +/-10% of input
voltage changing.
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.
Output voltage Min. load
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.
