ETE MV50P2S2 Multi-Voltage Control Transformer 50VA 20/0/380/420V to 10/0/220/240V

Why Choose the ETE MV50P2S2 50 VA Multi-Voltage Control Transformer?

The ETE MV50P2S2 is a 50 VA single-phase multi-voltage control transformer designed for industrial electrical installations requiring flexible primary voltage connections and tapped secondary output arrangements. Part of the ETE MV multi-voltage transformer range, it features 20/0/380/420 V primary terminals and 10/0/220/240 V secondary terminals, providing a versatile transformer configuration for compatible industrial control circuits.

The MV50P2S2 incorporates secondary terminals marked 0/220/240 V, together with a 10 V adjustment tap. These connections support the manufacturer's specified tapped-output arrangements for applications requiring appropriate AC control voltages. The exact output connection must follow the ETE datasheet, and the correct use of the 10 V adjustment tap must be confirmed with ETE before installation.

With its 50 VA rated capacity, the transformer is intended for compatible low-power industrial control equipment, including control relays, signalling circuits and other electrical devices requiring a suitable AC supply. Its multi-voltage primary arrangement provides flexibility for machinery and control panel applications where the manufacturer's specified primary connections are appropriate.

Featuring Class E insulation, 15% voltage regulation, compact dimensions of 75 × 65 × 88 mm and a weight of 1 kg, the ETE MV50P2S2 is suitable for integration into appropriately designed industrial electrical assemblies. The associated enclosure references are EPH 1 or EPN 1, providing identified enclosure options for installation planning.

Flexible Tapped AC Control Power for Industrial Electrical Systems

The ETE MV50P2S2 provides a practical solution for industrial applications requiring a compact, single-phase control transformer with multiple terminal connections. Its 20/0/380/420 V primary terminal arrangement and 10/0/220/240 V secondary terminal arrangement allow the transformer to be incorporated into compatible electrical systems using the manufacturer's specified wiring configurations.

The secondary winding includes terminals marked 220 V and 240 V, together with a 10 V adjustment tap. The output is specified as a tapped connection according to the ETE datasheet. Although the terminal markings identify available winding connections, they should not be treated as a substitute for the manufacturer's wiring diagram. Confirm the correct connections with ETE before energising the transformer, particularly when using the 10 V adjustment tap.

The transformer's 50 VA rated capacity is intended for compatible low-power control loads. Based on the apparent power rating, the calculated current corresponding to a 220 V output is approximately 0.23 A, while the calculated current corresponding to a 240 V output is approximately 0.21 A. These figures are theoretical calculations rather than separately verified manufacturer current ratings. They do not establish that every possible terminal combination is an approved output connection.

The specified 15% voltage regulation is important when evaluating secondary voltage variation between load conditions. Actual output voltage can vary with the primary supply and connected load, so equipment with narrow voltage tolerances should be assessed carefully. For control circuits containing relays, contactors or other inductive loads, both continuous apparent power and short-duration inrush requirements should be considered.

With Class E insulation, compact physical dimensions and associated EPH 1 or EPN 1 enclosure references, the MV50P2S2 can be integrated into suitably engineered industrial control assemblies. Appropriate mounting, primary and secondary circuit protection, conductor sizing, ventilation and electrical clearances should be provided in accordance with ETE installation instructions and applicable electrical requirements.
