Toroidal Transformers
Our toroidal transformers offer superior performance with lower electromagnetic interference, smaller size, lighter weight, and higher efficiency compared to conventional laminated transformers. Available in standard and custom configurations from 10 VA to 3000 VA.
Standard Toroidal Transformers
Our standard range covers 10 VA to 3000 VA with 0–230V AC primary voltage. All units meet international safety standards.

Custom Transformer Solutions
We design and manufacture custom transformers based on your requirements. Our engineering team works closely with customers to develop solutions optimised for electrical performance, mechanical constraints, and thermal conditions.
Frequency & Core Design
Transformers for 50 Hz to 10 kHz with nanocrystalline and optimised core materials. Winding configuration and size tuned for operating frequency and superior efficiency.
Thermal & Duty Cycle
Designs with temperature rise limited to 20°C above ambient. Continuous operation at elevated temperatures up to 200°C and short-time duty ratings available.
Mechanical & Mounting
Custom sizes and form factors including open frame, encapsulated, centre potted, captive inserts, DIN rail, PCB mount, and lifting hook configurations.
Regulation & Accuracy
Precision designs with 1% or 0.1% accuracy for instrumentation, measurement, control, and high-reliability applications.
Ruggedised & Protected
Shock and vibration rated units with potting, impregnation, and tropicalisation. Waterproof transformers rated for 100% relative humidity and harsh environments.
Electrical Specification
Custom input tolerances, regulation, temperature rise, ambient ratings, physical dimensions, and load & no-load condition parameters.
All designs account for input tolerances, regulation, temperature rise, and physical dimensions. Contact us with your requirements.
