21. Withstand Voltage
This module is designed to withstand applied voltage 2.5kVAC between input and baseplate, 3kVAC between
input and output for a duration of 1 minute. When doing this test during incoming inspection, set the current
limit of test equipment to 20mA.
This module is designed to withstand applied voltage 500VDC between output and baseplate for 1 minute. When
doing this test during incoming inspection, be sure to apply DC voltage only. Avoid applying AC voltage during
this test because this will damage the module.
Refrain from injecting high test voltage suddenly. Be sure to gradually increase the applied voltage during
testing and gradually reduce the voltage after the test.
Especially, when using timer switch of the test equipment, impulse voltage which is higher than the applied set
voltage, is generated when the timer switch is cut off. This causes damage to the power module.
Connect each
terminal according to the circuit diagram shown below.
For basic connection shown in Fig. 1-1, do the same terminal connections.
