The multi-frequency induction withstand voltage tester is a transformer induction withstand voltage test system. It belongs to inductive voltage tester. The output frequency of the unit is 150 Hz, (if 200 Hz is required, please specify), and the voltage is 0-800V (the domestic standard is 800V, if it is 1000V, please specify) , The capacity is 30KVA (the minimum capacity of the multiplier unit, please specify if you need a larger capacity). If the low-voltage voltage of the tested product exceeds 800V, the test needs to be completed by adding a step-up transformer.
The whole multi-frequency induction withstand voltage tester is composed of four parts, which are detailed as follows:
