Date: January 15, 2021Temperature: 20 ℃Relative humidity: 55%

5.1 Insulation resistance

Technical requirement: The insulation resistance of the power circuit to ground should not be less than 10OM Ω.

Actual measurement results: Please refer to the "Insulation Performance Test Table" for details.

Conclusion: Qualified

5.2 Dielectric Strength

Technical requirements: The power supply circuit should be able to withstand an AC withstand voltage test of 2000V at the power frequency for 1 minute, and the device should have no breakdown, flashover, or damage to components.

Actual measurement results: Please refer to the "Insulation Performance Test Table" for details.

Conclusion: Qualified

5.3 Impulse voltage

Technical requirements: The power circuit should be able to withstand a short-term impulse voltage test of standard lightning waves with an open circuit test voltage of 5kV and a voltage of 1.2/50 u s. The device allows for flashover, but there should be no insulation breakdown or damage.

Actual measurement results: Please refer to the "Insulation Performance Test Table" for details.

Conclusion: Qualified
