  • Impedance: 5.19% at 170° C
  • Insulation Class 220 with 150° C winding rise
  • Dry-type, air-cooled construction
  • Floor mount / freestanding configuration
  • Dimensions: 29 x 23 x 29.5 in; Weight: 524 lbs
  • Unit only; no accessories included

Applications

This transformer type is used in industrial drive systems to isolate VFD and motor drive circuits from facility power, reducing harmonic distortion and protecting sensitive plant equipment. Commonly installed in manufacturing, HVAC systems, and process control applications where adjustable speed drives require isolation.

Condition: Used
This Acme Electric DTGB-075-4S 75kVA Drive Isolation Transformer has been inspected and is in good used condition. It was pulled from a working environment where it was actively in service. The enclosure shows normal wear consistent with industrial use — the sheet metal housing has some minor surface scuffing and the nameplate label on the side panel is partially torn at the edges but the spec data remains legible. The interior shows three toroidal transformer cores in good physical condition with intact windings and terminal connections. Please view our photo set and contact us if you have any questions.
