Description
The windings are impregnated with resin of heat class H, and the transformer works without oil, so it is installed in rooms and electrical cabinets without the measures that oil-filled equipment requires. An isolating transformer galvanically separates the load from the mains, which is needed for measuring circuits, medical rooms and systems with an isolated neutral. An autotransformer is lighter at the same rating and suits cases when only the voltage levels need to be matched, for example for imported equipment. The IT M series consists of single-phase control transformers from IT M-25 to IT M-500. The primary winding is designed for two or three voltages, so one transformer is connected to different networks, and the secondary feeds contactor coils, relays and automation circuits.
How to choose
The task determines the scheme type. For galvanic isolation take an isolating IT, and for changing the voltage level without isolation an autotransformer. For control circuits in an electrical cabinet the IT M is selected by the total power of coils and signal lamps in the range from IT M-25 to IT M-500. When the voltage must be changed smoothly during operation, an adjustable toroidal ARC with a manual or servo drive is required.
