DM034KD - Hammond Power Solutions Drive Isolation Transformer 34kVA 480-240 3-Phase

DM034KD

DM034KD is a three-phase drive isolation transformer rated at 34kVA with 480 delta primary voltage and 240Y/139 secondary voltage, designed for industrial power distribution and variable frequency drive applications. This aluminum-wound transformer features robust construction with precision-wound conductors electrically balanced to minimize axial forces during short-circuit conditions. The unit complies with UL and CSA short circuit withstand requirements and meets IBC 2018 seismic standards. It operates at 45 dBA sound levels with typical impedance of 3 to 6 percent and is designed to withstand overcurrent of 150 percent of rated load for 60 seconds or 200 percent of rated load for 30 seconds.
