1. Insulation Resistance
The IR shall be at least 50MΩ when apply 500Vac between primary and secondary
2. Dielectric Strength ( Hi-POT )
Input to output 3750Vac 60Hz 1 minute 3mA. When AC voltage of 3.75kv is applied, and the voltage applied to the insulation under test is gradually raised from zero to the prescribed voltage in 1s, and held at that value for 60s between the inputs. Output and between the input and housing, the current sensitivity shall be less than 5mA. After this test, the adapter shall exhibit no electrical and mechanical abnormalities.
3. Leakage Current
The leakage current shall be less than 0.25mA for Class II when power supply is operated maximum input voltage and maximum load.
