Reliable Electrical Isolation and 110 V AC Control Power
Safety and isolating transformers provide electrical separation between primary and secondary circuits through transformer insulation. The ETE XMS300P5S4 converts a nominal 415 V AC single-phase supply into a 110 V AC secondary output, providing an isolated supply for appropriately rated industrial control circuits and electrical equipment.
The XMS series uses Class II construction with an integral moulded enclosure, eliminating the requirement for a protective earth connection to the transformer itself. Its IP20 touch-proof terminals, Class F insulation and chassis-mounted design make the XMS300P5S4 practical for use in industrial control cabinets, machinery panels and electrical equipment assemblies where dependable 110 V AC control power is required. The 300 VA rating provides capacity for compatible control loads while maintaining the benefits of an enclosed safety/isolating transformer.
Typical Applications
- Industrial electrical control panels requiring an isolated 110 V AC supply.
- Machinery control circuits supplied from 415 V AC systems.
- 110 V AC contactor, relay and control device circuits within the transformer rating.
- Industrial automation and machine control equipment.
- Electrical installations requiring Class II transformer construction.
- Building services and HVAC control systems.
- 110 V AC signalling and indication circuits.
- OEM electrical assemblies and chassis-mounted control equipment.
