Why Choose the ETE MV750P2S2 750 VA Multi-Voltage Control Transformer?
The ETE MV750P2S2 is a 750 VA single-phase multi-voltage control transformer designed for industrial electrical installations requiring selectable primary connections and a tapped secondary winding. Part of the ETE MV multi-voltage control transformer series, it features 20/0/380/420 V primary terminals and 10/0/220/240 V secondary terminals, providing a versatile solution for industrial control panels, machinery and automation equipment.
The transformer incorporates nominal 380 V and 420 V primary terminal selections, allowing integration into compatible industrial supply systems. Its secondary winding includes 220 V and 240 V terminal markings, together with a 10 V adjustment tap. The precise secondary output connection arrangement must follow the ETE datasheet, and the correct adjustment tap connections must be confirmed with ETE before installation.
With a rated capacity of 750 VA (0.75 kVA), the MV750P2S2 is suitable for supplying compatible AC control loads within its specified apparent power rating. Its 4% voltage regulation provides a useful specification for assessing secondary voltage variation between load conditions, while Class E insulation provides a defined thermal insulation classification.
Measuring 150 × 108 × 145 mm and weighing 7.6 kg, the ETE MV750P2S2 can be incorporated into appropriately designed industrial electrical assemblies. Its associated enclosure reference is EPN 3, supporting enclosure selection and control panel planning.

Reliable Multi-Voltage Control Power with Tapped Secondary Connections
The ETE MV750P2S2 is designed for industrial electrical installations requiring a dedicated control transformer with multiple voltage terminal selections. Its 20/0/380/420 V primary terminal arrangement includes nominal 380 V and 420 V terminal markings, allowing the appropriate input connection to be selected in accordance with ETE's instructions. The correct terminal arrangement should always be verified before the transformer is energised.
The secondary winding features 10/0/220/240 V terminal markings. These provide a tapped secondary arrangement incorporating nominal 220 V and 240 V positions together with a 10 V adjustment tap. However, the complete permissible output connection arrangements cannot be established from the terminal markings alone. ETE's datasheet must be followed, and the correct use of the 10 V adjustment tap must be confirmed with ETE.
At its rated 750 VA capacity, the calculated nominal secondary current is approximately 3.41 A at 220 V AC or 3.13 A at 240 V AC, assuming the corresponding output connection is approved by ETE. These figures are calculated from apparent power divided by nominal voltage and are not separately verified manufacturer current ratings. The transformer must not be loaded beyond its overall 750 VA rating or any additional winding and terminal limits specified by the manufacturer.
The specified 4% voltage regulation is relevant when assessing secondary voltage variation between load conditions. Actual output voltage depends on the incoming supply, selected primary and secondary connections and connected load. Control relays, contactor coils and other inductive equipment may introduce changing loads or short-duration inrush requirements, so both continuous apparent power and operating characteristics should be considered when selecting the transformer.
With Class E insulation, dimensions of 150 × 108 × 145 mm and a weight of 7.6 kg, the MV750P2S2 can be incorporated into appropriately engineered industrial control assemblies. Its EPN 3 enclosure reference assists with enclosure planning. Suitable mechanical support, circuit protection, conductor sizing, ventilation and electrical clearances should be provided in accordance with the manufacturer's installation instructions and applicable electrical requirements.
