| Aspect | Johsun Tec Advantage | Typical competitors |
|---|---|---|
| Voltage flexibility | One transformer can output multiple control and lighting voltages, customizable if needed. | Many standard transformers only offer one or two fixed voltage outputs. |
| Efficiency & size | Optimized core and winding design reduces losses and footprint. | Traditional designs often larger and less efficient. |
| Industrial reliability | Designed for continuous operation in control panels, machine tools, and automation systems. | Some generic transformers are not optimized for industrial control loads. |
| Safety & isolation | Focus on galvanic isolation and safety, aligned with IEC 60204‑1‑type standards. | Lower‑grade models may lack full isolation testing. |
| Customization | Support for special voltages, frequencies, and mounting sizes. | Limited or no custom options in many catalog brands. |

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.
Is it compatible with 50 Hz and 60 Hz systems?
Most models are designed for 50/60 Hz, suitable for worldwide grid systems.
Can special voltages (e.g., 24 V + 48 V) be customized?
Yes. Johsun Tec can customize winding turns and output voltages according to your specific equipment and voltage standards.
Do I need a professional to install a control transformer?
Installation should be done by a qualified electrician to ensure correct wiring, grounding, and compliance with local electrical codes.
