Lighting transformer

Application

The capacity is 50000VA and below, applicable to circuits with input voltage of 1000V and below and AC 50-60Hz. It can work continuously for a long time under rated capacity and is widely used in machine tools and mechanical equipment as local lighting and indicating power supply.

Structure characteristics

JMB, BJZ and DG series transformers are composed of BK series transformers and protective enclosures. There are terminals for input power and load wiring on both sides of the shell, and grounding screws for grounding; BZ series consists of BK series, master switch and protective shell. The master switch is equipped with a fuse to protect the lighting circuit. The power supply is introduced from the dust-proof film at the end of the master switch, which is used to turn on and turn off the lighting lamp.
