I. Overview

The BZ-H series lighting transformer is suitable for circuits with AC 50 or 60HZ, voltage 500V and below, and is commonly used as a local lighting power supply device for machine tools and other equipment. This type of transformer mainly consists of BK-50, BK-100 control transformers, LS3-2 main switch, and protective casing. A fuse is installed on the main switch to protect the lighting circuit. To prevent leakage, the secondary is connected to the grounding screw. The power is introduced from the dust-proof film on one end equipped with a master switch, and the lighting is controlled through the master switch.
