Appleton Electric - SHD DT651H118S 118KVA 460D-460Y SCR

Drive Isolation Transformers are designed for SCR (Silicon Control Rectifier) variable speed motor drive applications where a transformer is needed to magnetically isolate the incoming line from the motor drive. The transformer must also provide a voltage change to match the required voltage of the SCR Drive. Standard designs are delta primary and wye secondary to match the common power sources required in most three phase rectifier circuits. Features: UL, cULus; Available from 7.5 thru 440 kVA, 3 Phase, 60 Hz; Isolation minimizes load disturbances caused by the SCR drive; UL Listed/NEMA Type 3R enclosures when used with optional weather shield; Taps on all units for adjustments to incoming source voltage. Full capacity secondary neutral as required by the National Electric Code; Shielding attenuates line to ground noise
