Isolated Auxiliary Transformer
In StockAn Isolated Auxiliary Transformer is a precision-engineered electrical device designed to supply stable, low-voltage power to auxiliary systems while providing complete electrical isolation between the input (primary) and output (secondary) circuits. This galvanic isolation ensures safety, noise suppression, and protection of sensitive control equipment from voltage spikes, transients, and electrical disturbances in the main supply.
Widely used in industrial plants, power stations, control panels, CNC machinery, and automation systems, the Isolated Auxiliary Transformer delivers clean and interference-free power for control circuits, sensors, PLCs, and monitoring instrument.
