Products description

In low-voltage distribution system, control transformer is named because it is mostly used in control system. In fact, it is a step-down transformer with multiple output voltages, and can also be used as the power supply for low-voltage lighting, signal lights and indicator lights.

Two points should be paid attention to when usingthe controltransformer: one is the power of the transformer, and the other isthe correct wiring. The total power ofthe load connected to the secondary side (i.e. the secondary side) shall not be greater tharthe power ofthe control transformer, and short circuit is not allowed, 0therwise, the temperature will be too high, and it will beburned in case of serious problems. The primary and secondary (i.e. primary and secondary) wiring ofthe controltransformeshall not be wrongly connected, especially the primary side wiring. The voltage value that should be matched at the primary sideis marked on its terminal.lt is not allowed to connect the 380V power line to the 220V terminal, but the 220v power line can beconnected to the 380 Vterminal. Atthis time, all output voltages at the secondary side willbe reduced by 1.73 times. The secondanside load shall be connected to the corresponding terminal according to its rated voltage, for example, the 6.3 V indicator lampshallbe connected to the 6, 3 V terminal, the 36 V lighting bulb ofthe machine tool shall be connected to the 36V terminal. andthe 127 V AC contactor coil of the machine tool shall be connected to the 127 V terminal.

Scope of application

BK Series control transformer (hereinafter referred to as the transformer)50-60Hz apply voltage to 500V circuit.usually used as a tool to control local electric lights and power indicator light.

Structure fratures

BK Series transformer can be classified according to the structure of the shell and, by the way the installation can bedivided into vertical.
