Galvanic isolation separates the load circuit from the supply, so a fault on one side does not carry across to the other. An electrostatic shield between the windings attenuates the conducted noise that otherwise reaches sensitive electronics.
Frequently specified for medical, laboratory, IT and precision manufacturing loads.
- Full galvanic separation between primary and secondary
- Electrostatic shielding for conducted noise attenuation
- Eliminates earth loops between systems
- Protects sensitive electronic and measurement equipment
- Single- and three-phase, various enclosure ratings
- Custom voltage ratios on request
Medical facilities, laboratories, data and control rooms, precision manufacturing, test equipment and audio and broadcast installations.
Sourced from certified partner manufacturers and inspected against our own standard before dispatch. Routine tests — winding resistance, voltage ratio, no-load and load loss, dielectric strength and, on oil-filled units, leakage — are run on every transformer before release.
Third-party inspection by SGS, BV or another agency can be arranged on request, with the report issued before shipment. Designed and manufactured in compliance with IEC 60076, ANSI/IEEE and the destination market's requirements; CE documentation available. Warranty is 24 months from the date of shipment.
