DT661H220S

SolaHD drive isolation transformers magnetically isolate the incoming line from the motor drive for SCR variable speed motor drive applications. They also provide voltage change to match SCR Drive requirements.

The DT661H220S transformer has a 220 kVA rating and supports a 200 horsepower drive.

The DT661H220S measures 46.00 in high, 36.00 in wide, and 24.00 in deep, with an approximate shipping weight of 1280.0 lbs.

The DT661H220S has a 460 Delta Primary and a 230Y/133 Secondary voltage configuration.

These transformers are UL Listed under E77014 (UL 506, CSA C22.2 No. 66) and E25872 (UL 1561).

The compatible weather shield for the DT661H220S is model WS-11. Weather shields come in a set of two and must be ordered separately.

SolaHD drive isolation transformers come with a 10-year limited warranty.

These transformers are specifically designed for SCR (Silicon Control Rectifier) variable speed motor drive applications.

Key features include isolation to minimize load disturbances, voltage adjustment taps, full capacity secondary neutral, and shielding to attenuate line to ground noise. They also come with a 10-year limited warranty.

Yes, NEMA Type 3R enclosures are achieved when the transformer is used with an optional weather shield, which must be ordered separately.
