An industrial control transformer is designed to provide a reliable secondary voltage for control circuits, contactors, relays, solenoid valves, PLC systems, sensors, machine tools, and industrial automation equipment. It helps separate and supply control circuits from the main power circuit.

The three series are designed for different industrial applications. BK Series is a general-purpose control transformer for machinery and electrical control systems. JBK Series is commonly used in machine tools, CNC equipment, and industrial control cabinets. JMB Series is optimized for lighting, control circuits, and local power supply applications. The best series depends on the equipment, installation method, voltage, and load requirements.

Select the transformer based on the total VA load of the connected control components and their starting or inrush requirements. For applications with contactors, solenoids, motors, or multiple inductive loads, additional capacity should be considered to maintain stable secondary voltage during energization.

Voltnex Power can manufacture control transformers with a wide range of primary and secondary voltage configurations, including common industrial voltages such as 220V, 380V, 400V, 415V, 440V, and 660V, with secondary voltages such as 24V, 36V, 110V, and 220V. Custom voltage combinations and multi-tap configurations are also available.

Yes. Custom manufacturing is available for voltage ratios, VA ratings, frequency, winding material, insulation class, terminal configuration, mounting dimensions, enclosure requirements, and other application-specific specifications. OEM and ODM solutions can also be developed for equipment manufacturers.

Yes. Both copper and aluminum winding options can be considered according to the required electrical performance and project budget. Copper windings are commonly selected when high conductivity, efficiency, and compact dimensions are priorities.

Yes. Control transformers can be designed for 50Hz or 60Hz applications. The required frequency should be specified when ordering so that the transformer can be correctly designed and manufactured for the intended power system.

Depending on the model and application, insulation systems such as Class B, Class F, and Class H can be specified. The appropriate insulation class is selected according to operating temperature, installation conditions, duty cycle, and required service life.

Yes. Control transformers are widely used in CNC machines, machine tools, automated production equipment, electrical control cabinets, and industrial machinery. JBK Series transformers are particularly suitable for machine-tool and industrial control applications where stable control voltage is required.

Yes. Compact control transformer designs can be installed inside electrical control cabinets, machine control panels, CNC cabinets, automation systems, and industrial equipment. Installation should provide sufficient ventilation, appropriate clearances, and secure mechanical mounting.

A control transformer is primarily selected to supply control circuits and accommodate the inrush characteristics of devices such as contactors and solenoids. An isolation transformer is primarily selected for electrical isolation between the input and output circuits. The correct choice depends on whether the main requirement is control power, electrical isolation, or both.

Yes. Voltnex Power provides OEM and ODM manufacturing for industrial equipment manufacturers, control-panel builders, machine-tool manufacturers, automation companies, and electrical system integrators. Transformers can be produced according to customer drawings, specifications, electrical requirements, and installation dimensions.

For an accurate quotation, provide the primary voltage, secondary voltage, VA/kVA capacity, frequency, phase, winding material, insulation requirements, quantity, and application. Drawings, mounting dimensions, terminal requirements, or equipment specifications are also helpful for customized projects.

Lead time depends on the model, capacity, quantity, customization requirements, and current production schedule. Standard configurations can generally be produced faster, while OEM and customized transformers may require additional engineering and manufacturing time. Voltnex Power provides a confirmed production schedule with each quotation.

Yes. Voltnex Power supplies industrial control transformers for international B2B projects and can support customized voltage configurations, technical documentation, packaging, and export shipment requirements. Customers can request specifications and quotations for projects in North America, Europe, Latin America, Southeast Asia, the Middle East, Africa, and other markets.
