Overview

The Hammond Power DM027KK is a three-phase drive isolation transformer with a 27 kVA rating. It features aluminum windings and operates with a 480V input and 480V output. This transformer is specifically designed for variable speed drive (VSD) applications, providing essential isolation to protect AC and DC drives. It effectively mitigates electrical noise, harmonics, and voltage spikes that can compromise drive performance and longevity. The aluminum construction offers a lightweight yet durable solution with efficient thermal management, contributing to reduced installation and maintenance overhead. Engineered for industrial settings where power quality and equipment reliability are paramount, the DM027KK meets the operational demands of modern drive systems. Its compact design facilitates integration into standard electrical panels or custom enclosures, delivering a cost-effective approach to voltage regulation and harmonic suppression in variable frequency drive (VFD) systems. The UNSPSC code for this product is 39121001, and it is manufactured in the US.
