JMB, BJZ, DG, the BZ series lighting transformer is suitable in exchanges 50HZ, in voltage 500V and the following electric circuit, takes the engine bed and other equipment's partial flare power source.

JMB, BJZ, the DG series transformer is by TP-DK the series transformer and the protective covering constitution, the outer covering both sides has for inputs the wiring column which the power source and the load wiring use, and has the earthing screw which uses for the earth; The BZ lighting transformer is by TP-DK 50, TP-DK 100 controls the transformer, LS3-2 to order the switch and the protective casing is composed, in orders on the switch to be loaded with the fuse, with protects the illumination return route, the power source from is loaded with orders a switch end the dustproof thin film to pull into, through orders the switch to put through and the breaking flare.

JMB, BJZ, DG, BZ series illumination, portable lamp control transformer technology characteristic

primary secondary circles the system separately, when secondary when a winding, it shoulders the transformer completely the rated capacity, when secondary like has at the same time the control, the illumination and the indicating lamp winding, presses various windings capacity assignment to circle the system separately, to simplex winding, and has intermediate tap's transformer its each intermediate tap capacity, is smaller than transformer's rated capacity, only then the overvoltage out-port may shoulder the rated capacity.
