Control transformers provide a suitable secondary voltage for electrical control equipment while providing electrical isolation between primary and secondary windings. The ETE MV750P1S3 converts a compatible 220/240 V AC supply into low-voltage AC power for control circuits, signalling devices, relays and industrial automation components.
The transformer incorporates two separate 12 V secondary windings, allowing flexible connection arrangements. When connected correctly in parallel, the windings provide a 12 V AC output with their combined current capability. When connected correctly in series, they provide a 24 V AC output. The total transformer capacity remains 750 VA in either arrangement, subject to the manufacturer's connection instructions and operating conditions.
The primary winding also incorporates a 10 V adjustment tap. The correct primary terminal connections, including the adjustment tap arrangement, must be confirmed with ETE before installation. Proper secondary winding polarity and connection arrangements are essential when configuring the transformer for series or parallel operation.
Typical Applications
- Industrial electrical control panels and switchgear assemblies.
- 24 V AC control circuits for contactors, relays and control equipment.
- 12 V AC industrial control and signalling circuits.
- Machinery control cabinets and OEM automation equipment.
- Industrial process control and production machinery.
- Electrical isolation and low-voltage AC supply distribution.
- Control circuits in manufacturing and material handling systems.
- Replacement and maintenance of compatible industrial control transformers.
