1 heating time

Under the test voltage, the component should rise from ambient temperature to test temperature for no more than 15 minutes.

2 rated power deviation

Under the condition of sufficient heat generation, the deviation of the rated power of the component shall not exceed the range specified below; for components with rated power less than or equal to 100W: ±10%.

For components with rated power greater than 100W, it is +5% to -10% or 10W, whichever is greater.

3. The leakage current of the leakage current and the leakage current after the water pressure and sealing test shall not exceed 0.5 mA; the thermal leakage current at the working temperature shall not exceed the calculated value in the formula, but the maximum does not exceed 5 mA.
