In addition to our extensive program of standard design transformers, we offer you custom toroidal transformers to your exact specifications. Besides using ordinary toroidal cores we also design transformers using the low profile O-cores. You can read more about our O-core transformers and their advantages and benefits by clicking on the O-core link. Just like our standard program we offer custom designed transformers certified to UL safety standards for both general-purpose applications and medical applications.

Our General Purpose transformers carry certification to UL506 and IEC742 up to 10,000 VA, while our medical transformers are certified to UL60601.1, CSA std c22.2 No.601.1, EN61558-1 and IEC601.1 up to 6,000 VA. We have winding capabilities to make transformers up to 20,000 VA in full compliance to the above-mentioned standards.

Please feel free to use the design form on our website or send us your own via email or FAX.
To design a transformer with optimum performance and lowest possible price we must know your application and duty cycle (if not continuous 100% load) of the transformer. The most cost effective design uses a core with diameter to height ratio of 2:1, Click on our Design Guide link for more details.
