EPR-91 Datasheet, PDF (30/36 Pages) Power Integrations, Inc. – Engineering Prototype Report for EP-91 - 12 W Power Supply using

EP-91 12 V, 1 A, Universal Input Supply
7-Feb-2006
13 Conducted EMI
Conducted emissions tests were performed at 115 VAC and 230 VAC at full load (12 V,
1 A). Measurements were taken with an Artificial Hand connected and a floating DC
output load resistor. A DC output cable was included.
Composite EN55022B / CISPR22B conducted limits are shown. In all cases there was
excellent (>10 dB) margin.
