Low voltage high current transformer

Overview of low voltage high current transformer

Low-voltage high-current transformer series is suitable for continuous load test of switches, current transformers, diamonds, short-circuit heating and other electrical equipment with a rated frequency of 50 Hz for up-current and heating. Generally, it is necessary to add voltage adjustment on the front side of the power supply to make the low voltage side achieve stepless voltage regulation.
