BKZ series silicon rectifier power supply deviceDetailed product description：

1、 Scope of application

The BKZ series rectifier device is composed of a BK transformer and rectifier components. Transformers are suitable for power supplies with a primary voltage of 220V or 380V and an AC frequency of 50Hz. The output voltage is rectified by a transistor rectifier element to produce a DC output, which is used for charging batteries and converting AC power into DC power for use in equipment.
