Reliable 6.25 kVA Tapped AC Control Power for Demanding Industrial Applications

The ETE MV6250P2S2 provides a high-capacity 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 a compatible industrial AC supply must be transformed to an appropriate AC control or auxiliary voltage.

The primary winding incorporates terminals marked 380 V and 420 V, together with additional terminals marked 20 V and 0 V. These markings identify the available winding connections but do not independently establish every permissible supply voltage combination. The exact primary terminal arrangement should be verified against ETE's approved wiring diagram before the transformer is energised.

The secondary winding features terminals marked 220 V and 240 V, together with a 10 V adjustment tap. The manufacturer's specification describes the output as a tapped output, with the correct terminal configuration defined by the datasheet. The 10 V terminal should not be assumed to provide an independent 10 V output, and the relationship between the secondary terminals must be confirmed with ETE.

At the total rated apparent power of 6250 VA, the calculated current equivalents are approximately 28.41 A at 220 V and 26.04 A at 240 V. These figures are calculated by dividing the rated apparent power by the nominal secondary voltage. They are theoretical values for the respective voltage levels rather than independently verified current ratings for every tapped output configuration. The permitted winding and tap loading limits must be checked before finalising the connected load.

The specified 3% voltage regulation is relevant when selecting transformers for industrial circuits containing equipment with changing electrical loads. Contactors, relays, solenoids and other electromagnetic devices can draw greater apparent power during energisation than during normal operation. Electrical designers should assess the aggregate steady-state load, simultaneous switching demands and acceptable operating voltage range of connected equipment.

The MV6250P2S2 features Class F insulation, a recognised transformer insulation thermal classification. This provides a defined basis for insulation selection, although the transformer's permissible ambient temperature, operating duty and thermal installation conditions should be confirmed against the manufacturer's technical documentation.

With a rated capacity of 6.25 kVA, the MV6250P2S2 is particularly relevant to larger industrial installations containing multiple compatible AC electrical loads. Transformer selection should consider the total apparent power requirement, winding-specific current limits, starting demands and the suitability of the selected primary and secondary connections.

The transformer measures 245 × 250 × 230 mm and weighs 58 kg. Its substantial weight requires appropriate consideration of lifting, handling, secure mounting and mechanical support. The specified compatible enclosure reference is ETE EPN 7, with final installation arrangements dependent on the intended operating environment and ventilation requirements.

The MV6250P2S2 provides AC voltage transformation rather than regulated DC output. Equipment requiring DC control voltage will need suitable additional conversion components. Installation should account for correct primary and secondary terminal selection, appropriately rated circuit protection, conductor sizing, secure mounting, ventilation and protective earthing where applicable.
