Product Overview
EATON's Motor Drive Isolation Transformers are available in a wide range of ratings to meet specific voltage conversion requirements. They provide electrical isolation between the incoming line and drive circuitry, voltage conversion on input line to standard drive input voltages, minimize line disturbances caused by SCR firing and reduce short-circuit currents and voltage line transients.

For use with AC and DC adjustable speed drives
- Short-term overload capability as required by ANSI
- Primary and secondary terminals are front accessible for fast and easy connection
- Slotted screw mounting holes in enclosure and cover reduce installation time
- Sound dampening pads, which isolate the core and coil from the case, reduce noise levels to meet NEMA ST-20
- Core laminations of precision sheared silicon steel are hand stacked to ensure quiet operation
- Terminations are clearly marked for easy identification
- 3 ph transformers have one 5% full capacity tap above and below nominal voltage for incoming source adjustment
- Units are suitable for continuous operation in a 40 deg C ambient maximum
- Full current neutral
- Thermoguard protection embedded in coils of three phase models to indicate that high temperatures (approximately 190 deg C) are present
- Thermoguards consist of a set of NC dry contacts
- Three coil delta-wye configurations are used throughout the product line
