Safety Standards for Medical Electronics Industry

Transformer products used in the medical electronics industry must meet stringent safety standards according to UL544 or equivalent foreign safety standards (CSA c22.2 No. 125, VDE 0551, IEC 601.1). For patient connected equipment, extra low leakage currents are required and must be specified by the customer. We guarantee leakage currents as low as 10uA when requested. UL family recognition to UL544 is available for class A and class B insulation systems.

Safety Standards for Non-Medical Applications

All our transformers for non-medical applications are designed to comply with UL1411 or UL1950. When requested, the transformers will also comply with equivalent foreign safety standards (CSA c22.2 No.66, 1988 revision, VDE 0550, IEC 742, EN 60742 or IEC 1950). UL family recognition is available for class A and class B insulation systems.

International Safety Standards

As mentioned above, we are thoroughly familiar with the various foreign safety standards. We offer our assistance to have our custom designed transformers tested by TUV or other testing laboratories you choose to do the evaluation. All our transformers are built with required creep distance and insulation system to pass 4000V Hi-pot test between primaries and secondaries. Our technical bulletin No. 2 gives you helpful information on recommended primary windings for overseas markets.
