Why Choose the ETE MV500P2S2 500 VA Multi-Voltage Control Transformer?
The ETE MV500P2S2 is a 500 VA single-phase multi-voltage control transformer designed for industrial electrical control panels, machinery and automation systems requiring flexible AC voltage transformation. Part of the ETE MV multi-voltage control transformer range, this model features 20/0/380/420 V primary terminals and 10/0/220/240 V secondary terminals, providing a tapped output arrangement for compatible industrial control circuits.
The MV500P2S2 combines a substantial 500 VA apparent power rating with multiple primary and secondary winding connections. Its primary winding incorporates terminals marked 380 V and 420 V, while the secondary winding includes terminals marked 220 V and 240 V, together with a 10 V adjustment tap. The exact output configuration and adjustment tap connections must be confirmed using ETE's approved wiring information before installation.
This multi-voltage arrangement makes the transformer particularly useful for electrical panel builders and machinery manufacturers working with industrial AC supplies and compatible higher-voltage control equipment. The tapped secondary winding provides flexibility when selecting an appropriate output connection, helping accommodate different control circuit requirements within one transformer model.
Featuring Class E insulation and 8% voltage regulation, the ETE MV500P2S2 provides defined electrical characteristics for transformer selection. Its dimensions of 120 × 120 × 120 mm and weight of 6.2 kg support integration into suitably designed industrial electrical cabinets. The specified compatible enclosure references are ETE EPH 3 or EPN 2.

Reliable 500 VA Tapped AC Control Power for Industrial Electrical Systems
The ETE MV500P2S2 provides a flexible solution for industrial electrical installations requiring a transformer with multiple primary and secondary connection options. Its 20/0/380/420 V primary winding and 10/0/220/240 V secondary winding make it suitable for applications where an industrial AC supply must be transformed to a compatible AC control voltage.
The primary winding incorporates terminals marked 380 V and 420 V, together with an additional 20 V terminal. These markings identify the available winding connections but do not independently establish every permissible supply voltage combination. The exact primary connection arrangement should be verified against ETE's approved wiring diagram before installation.
The secondary winding features terminals marked 220 V and 240 V, together with a 10 V adjustment tap. The specified output arrangement is a tapped output according to the manufacturer's connection information. The 10 V terminal should not be assumed to provide an independent 10 V output, and the correct relationship between the secondary terminals must be confirmed with ETE.
At the total rated apparent power of 500 VA, the calculated current equivalents are approximately 2.27 A at 220 V and 2.08 A at 240 V. These figures are calculated by dividing the rated apparent power by the nominal voltage. They should not be interpreted as independently verified current ratings for every tapped connection arrangement. The permissible winding and tap loading limits should be checked before selecting the final connected load.
The specified 8% voltage regulation is relevant when designing industrial control circuits containing electromagnetic devices. Contactors, relays and solenoids may draw greater apparent power during energisation than during normal operation, potentially affecting the secondary voltage. Electrical designers should therefore assess both steady-state load and simultaneous switching requirements.
With Class E insulation, dimensions of 120 × 120 × 120 mm and a weight of 6.2 kg, the MV500P2S2 can be integrated into appropriately designed industrial electrical cabinets. Its specified EPH 3 or EPN 2 enclosure references provide compatible housing options where additional physical protection is required.
The MV500P2S2 provides AC voltage transformation rather than regulated DC output. Correct primary and secondary terminal selection, suitable circuit protection, conductor sizing, mechanical mounting, ventilation and protective earthing where applicable should be considered during installation. All adjustment tap connections must be verified against ETE's approved technical information before energising the transformer.
