PST-1200MF Adaptor/Power Supply Test Report

 

Load Current / mA Voltage / V Noise dB
12.6  12.83 60mV p-p 333kHz  -46.6
101.4  12.81    
210  12.78    
550  12.68    
1000  12.55  10mV  -62
1200  12.49 <15mV 8mS, 120Hz  -58
1500  12.38    
1600  12.33    

 Remarks:

 1. Regulation held at about 2.5% of better from 100mA to 1200mA.

 2. Noise is 58 dB down at full load. This is excellent. Most equipment run by

    this type of adapter has additional internal filtering.

 3. Exceeding ratings for too long caused transistors to short which burned out

    internal fuse and ended tests. 

 Conclusion:

 Operating this unit at or under published ratings should give long life.
