DT661H93S

SolaHD Drive Isolation Transformers are designed for SCR (Silicon Control Rectifier) variable speed motor drive applications. They magnetically isolate the incoming line from the motor drive.

These transformers are available from 7.5 kVA through 440 kVA, in 3 Phase, 60 Hz configurations.

Yes, all units include taps for adjustments to the incoming source voltage. They also feature a full capacity secondary neutral as required by the National Electric Code.

SolaHD Drive Isolation Transformers come with a 10-year limited warranty.

All models are UL Listed (E25872 UL 1561 or E77014 UL 5085) and RoHS Compliant. Some models are also cULus E77014 and CSA marked.

The 93 kVA transformer (EDT661H93S) has dimensions of 34.00 in height, 28.00 in width, and 26.00 in depth.

The approximate shipping weight for the 93 kVA model (EDT661H93S) is 637.0 lbs (289.00 kg).

For the DT661H93S (Group II), the primary voltage is 460 Delta and the secondary voltage is 230Y/133.

For a 460 Delta primary, the available tap settings are 483V, 460V, and 437V. For a 575 Delta primary, settings are 604V, 575V, and 546V.

A drive isolation transformer magnetically isolates the incoming line from the motor drive and provides a voltage change to match the SCR Drive's required voltage.
