Microwave oven door Switch monitoring interlock device failure test impedance 0.4+j0.25ω
In the microwave oven safety test, it is necessary to do the failure test of the open-close chain monitoring. In this connection, the IEC 60335-2-25 requires a (0.4+j0.25) Ω test impedance to be connected in series to the circuit. The impedance of the microwave oven is designed according to this requirement. Second, the specification parameter: working voltage; AC220V 50Hz operating current: ≤40a.
First, overview:
