Single-phase transformers operate on single-phase AC power that converts a convenient voltage into much higher voltage and distributes the power supply for use in lighting & power applications. Raptor Supplies offers a wide range of these switches from Acme Electric, Intermatic and Square D. These units are integrated with primary and secondary windings that are ground shielded for safe operation and help to transfer electric energy through electromagnetic induction between two coils. They further feature built-in circuit protection to safely disconnect power temporarily in overload conditions. Choose from a wide range of these transformers, available in 12, 110 / 220 and 120 / 240VAC output voltage ratings on Raptor Supplies.
