Why Choose the ETE MV750P2S1 750 VA Control Transformer?
The ETE MV750P2S1 is a robust and reliable 750 VA single-phase control transformer designed to provide dependable low-voltage AC power for industrial control circuits, electrical panels and automation equipment. Part of the ETE MV multi-voltage control transformer series, it features selectable primary voltage connections and a tapped secondary winding, providing flexible voltage conversion for industrial machinery and electrical installations.
The MV750P2S1 features 20/0/380/420 V AC primary terminals and 0/55/110 V AC secondary terminals. It supports nominal primary supply connections of 380 V AC or 420 V AC, with selectable 55 V AC or 110 V AC secondary outputs. The additional 20 V primary adjustment tap provides a further connection option, although its correct configuration must be confirmed with ETE before installation.
With a rated apparent power of 750 VA, Class E insulation and 4% voltage regulation, the MV750P2S1 is suitable for industrial applications requiring reliable AC control voltage. Its compact 150 × 108 × 145 mm construction, 7.6 kg weight and specified EPN 3 enclosure compatibility make it a practical choice for electrical panel builders, OEM manufacturers and industrial automation engineers.

The ETE MV750P2S1 control transformer uses electromagnetic induction to convert a higher single-phase AC supply voltage into a lower AC voltage suitable for industrial control and auxiliary equipment. Its multi-voltage primary winding provides nominal connections for 380 V AC and 420 V AC supplies, allowing the appropriate primary terminal to be selected for the installation.
The transformer incorporates an additional 20 V primary adjustment tap, identified within its 20/0/380/420 V terminal arrangement. This adjustment tap must not be treated as an independent 20 V supply input. Its intended use and correct connection arrangement should be confirmed directly with ETE before wiring or energising the transformer.
Unlike control transformers with two separate secondary windings for series or parallel connection, the MV750P2S1 features a tapped secondary winding with terminals marked 0/55/110 V. This allows the required nominal output to be selected from the 55 V AC or 110 V AC taps. At the full 750 VA rating, the calculated output current is approximately 6.82 A at 110 V AC. The equivalent calculated current at 55 V AC is 13.64 A, although the permissible load on the intermediate tap must be confirmed against ETE's winding and terminal ratings.
With Class E insulation and 4% voltage regulation, the MV750P2S1 provides a practical solution for industrial control circuits requiring selectable AC voltages. Its compact construction supports integration into electrical panels and machinery cabinets, while the specified EPN 3 enclosure provides a compatible housing option. Primary tap selection, secondary connections, earthing and protective devices must follow the manufacturer's installation instructions.
