What is a control transformer and why is it important?

A control transformer steps down high mains voltage to low voltages for control circuits, PLC inputs, relays, and signal lamps, while providing electrical isolation and stable voltage under varying loads.

What voltage inputs are supported?

Typical inputs are 220 V and 380 V (50/60 Hz); other voltages such as 400 V/415 V/440 V can be customized upon request.

Can one transformer output multiple voltages?

Yes. JBK3‑series transformers can provide several secondary voltages (e.g., 6 V, 24 V, 36 V, 110 V, 220 V) in one unit, depending on model and configuration.

Which applications are suitable?

Control panels, machine tools, automation systems, production lines, and industrial control circuits for relay, PLC, and lighting/signal lamp power supply.
