Product Overview
Eaton's Motor Drive Isolation Transformers are manufactured using high-quality construction and 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.

AC and DC Adjustable Speed Drives and Indoor Applications
- Thermal sensors embedded in coils can be wired to provide a signal to remote locations, indicating potential heating problems within the transformer coils
- Get fast and easy connection with front accessible primary and secondary terminals
- Easily identify terminals with clear labeling
- Reduce installation time with slotted screw mounting holes in enclosure and cover
- Reduce noise levels to meet NEMA ST-20 with sound dampening pads that isolate the core and coil from the case
- Short term overload capability as required by ANSI
- Core laminations of precision sheared silicon steel are hand stacked to ensure quiet operation
- Terminations are clearly marked for easy identification
- 3-phase transformers have one 5% full capacity tap above and below nominal voltage for incoming source adjustment
- Full current neutral
- Thermoguard protection embedded in coils of 3-phase models to indicate that high temperatures (approximately 190 deg C) are present
- Three coil delta-wye configurations are used throughout the product line
- Aluminum windings
- 1 at +5% FCAN, 1 at -5% FCBN taps
