PowerHome three-phase isolation transformers are engineered for industrial and commercial power supply applications where voltage conversion, galvanic isolation, and protection against electrical disturbances are required at scale.

Covering capacities from 3 kVA to 300 kVA, the range spans step-down, step-up, and bidirectional configurations across the most common international voltage pairs — including 480V/400V, 480V/380V, 415V/208V, 400V/240V, 380V/220V, and more.

All units are dry-type, air self-cooled, Dyn11 wired, and rated for continuous duty on AC 50 Hz and 60 Hz grids. Units rated at 150 kVA and above include a built-in temperature alarm for overtemperature protection. Primary and secondary voltages are independently selectable and customisable, with aluminium or copper windings, open type or IP 24 enclosure, and optional movable wheels — CE and ISO certified for deployment across North America, Europe, the UK, India, the Middle East, and Asia-Pacific.
