3.KZX-5KVA Dual voltage regulation controller
Product Features
This series of consoles is suitable for voltage regulation control of 0.5-5KVA test transformers. Working principle: By adjusting the output voltage of the autotransformer, the working adjustment within the rated voltage range of the test transformer can be achieved. The console is equipped with a high-voltage output voltmeter and a low-voltage output ammeter, which can easily read out the test voltage value. By using overcurrent protection circuits to reliably protect equipment, the designed timing alarm circuit makes testing more convenient. It has been proven by users that its principle is simple, its structure is compact, its work is reliable, and its use is convenient, making it an ideal equipment for high-voltage testing.
