The BK Series Single-Phase Control Transformer is an essential power conversion solution widely used in industrial automation systems, machine tool control circuits, signal light supplies, and control panel assemblies. Engineered for step-down or isolation applications, the BK transformer ensures continuous, safe, and highly stable low-voltage operation for sensitive relay systems and modern electronic controllers.

Manufactured with high-quality cold-rolled silicon steel laminations and heat-resistant insulated copper wire, our BK dry-type control transformers comply with IEC 60076, ISO9001 international safety standards, making them a trusted choice for OEM machinery manufacturers and panel builders worldwide.

Multi-Voltage Taps (Customizable): Flexible primary and secondary multi-tap voltage design to meet various international electrical grid standards (e.g., 380V/220V input to 24V/110V output).

Compact & Rugged Construction: Small footprint with sturdy mounting brackets, allowing easy integration inside compact electrical control cabinets.

Low Noise & High Efficiency: Precision-stacked core structure reduces core loss, magnetic leakage, and acoustic noise during long hours of continuous operation.

Safe Terminal Block Design: Equipped with insulated, flame-retardant terminal blocks and clear wire marking tags for easy and safe wiring connections.

Superior Overload Resistance: Exceptional thermal endurance (Class B/F/H insulation options available) designed to handle inductive inrush current from motor contactors and relays.
