Available with configurable primary and secondary voltages (standard: 380V / 400V / 415V) and rated for 50Hz or 60Hz systems, this transformer is designed for low-voltage networks (<1kV). Its dry, air-cooled construction eliminates oil, reduces fire risk and lowers routine maintenance — making it a safe, cost-effective choice for motor control centers, CNC systems, PLC cabinets and distribution panels.

GBK2 Single Phase 220v To 220v Toroidal Balanced Isolation Transformer 300va-2Kva

Ensure pristine power quality and maximum safety for sensitive loads with the GBK2 toroidal isolation transformer. Designed for applications that demand low noise, low leakage and stable output (220V → 220V), the GBK2 series isolates your equipment from mains disturbances, suppresses transients and reduces common-mode interference. Its compact toroidal core delivers higher efficiency and lower audible hum than conventional laminated transformers—ideal for medical devices, pro audio, laboratory instruments and industrial controls.

JBK 25va-5000va Single Phase Dry Type Machine Control Isolation Transformer 220v to 110v

The JBK series is a compact dry-type control transformer designed for machine control and isolation in industrial panels. Typical use is 220 V → 110 V control circuits for contactors, relays, PLCs and sensors. Built for low noise, high reliability and easy cabinet mounting, JBK protects control circuits from mains disturbances while simplifying wiring and maintenance.

SG 10kva-1000kva Three Phase Dry Type Isolation Step Down Transformer

The SG series three-phase dry type isolation transformer is a high-performance power solution engineered for AC 50 Hz–60 Hz circuits up to 660 V. Designed for industrial production lines, data centers, precision machine tools, medical equipment, and imported critical devices, it provides electrical isolation, stable voltage conversion, and superior noise suppression. With a capacity range of 10 kVA to 1000 kVA, this transformer meets and exceeds international standards including IEC 439 and GB 5226, delivering dependable power where safety and efficiency are paramount.

Bk100va-5kva Single Phase Isolation Control Power Transformer

The BK series single-phase isolation control power transformer (commonly called a BK transformer) delivers stable, isolated control voltages for industrial and commercial equipment. Available from 100 VA to 5 kVA, the unit uses a thyristor (SCR) control module with feedback to provide precise closed-loop voltage regulation even when the input supply fluctuates.

This control transformer is built to international safety and efficiency standards and is perfect for CNC machines, PLCs, automation panels, lighting circuits, and other precision systems that need a stable control supply.
