Measured with Line Frequency Harmonics EN61000-3-2 Class A scope probe directly across output terminals of the power supply with load Earth Leakage Current terminated with 0.1 μF capacitor. Leakage current measured in the Gnd wire connection when measured per EN60601-1 or UL2601-1 is as follows: Overvoltage Protection Built in with firing point set per ratings table. OVP firing reduces voltage to Medical Normal SingleFault Test Test less than 50% of nominal voltage in 50 ms.
