An isolation transformer separates the primary supply from the secondary load through galvanic isolation — eliminating ground loops, suppressing common-mode noise, reducing power surges, and providing an increased level of protection against electric shock.

PowerHome offers a comprehensive range of single-phase and three-phase isolation transformers from 0.5 kVA to 300 kVA, covering step-up, step-down, and same-voltage isolation configurations. All units are dry-type, air self-cooled, CE and ISO certified, and compatible with AC 50 Hz and 60 Hz power systems — with flexible voltage selection on both primary and secondary sides to suit international grid standards across North America, Europe, the UK, India, the Middle East, and Asia-Pacific. Available with aluminium or copper windings, open type or IP 24 enclosure, and optional movable wheels.
