Why Choose the ETE MV6250P2S1 6250 VA Multi-Voltage Control Transformer?
The ETE MV6250P2S1 is a high-capacity 6250 VA (6.25 kVA) single-phase multi-voltage control transformer designed for industrial electrical control systems, machinery, switchgear and automation equipment. Part of the ETE MV stock control transformer range, it provides flexible primary voltage selection and a tapped secondary winding for applications requiring reliable AC voltage conversion and electrical isolation.
The MV6250P2S1 features a 20/0/380/420 V primary terminal arrangement for compatible 380 V and 420 V AC supplies. Its 0/55/110 V secondary terminals provide selectable 55 V or 110 V AC outputs, making it suitable for industrial equipment operating at different control voltages. A 20 V primary adjustment tap provides additional connection flexibility, with the correct terminal arrangements to be confirmed with ETE.
With a substantial 6250 VA power rating, Class F insulation and 3% voltage regulation, the MV6250P2S1 is designed for demanding industrial installations. Measuring 245 × 250 × 230 mm and weighing 58 kg, it requires appropriate mechanical support and installation space. The specified enclosure reference is EPN 7.

Industrial control transformers provide voltage conversion and electrical isolation for control circuits and compatible electrical equipment. The ETE MV6250P2S1 is designed to operate from suitable 380 V or 420 V AC primary supplies and deliver a selectable 55 V or 110 V AC secondary output. This makes it suitable for industrial installations where a higher-voltage AC supply must be converted to a lower control voltage.
The transformer uses a 0/55/110 V tapped secondary winding, allowing the required voltage to be selected using the appropriate terminals. Its 20/0/380/420 V primary arrangement incorporates a 20 V adjustment tap. The correct use of this tap and the associated terminal connections must be confirmed with ETE before energising the transformer.
At 110 V AC, the theoretical full-load secondary current calculated from the 6250 VA rating is approximately 56.8 A. At 55 V AC, the mathematical equivalent of the full rated power is approximately 113.6 A; however, the actual permissible loading of the 55 V tap must be verified with ETE. A tapped secondary winding must not automatically be assumed to provide the full transformer rating at every voltage selection.
The transformer's 3% voltage regulation supports consistent output performance, while its Class F insulation system provides thermal insulation suitable for industrial transformer applications. Its 58 kg weight requires appropriate lifting, handling and mounting arrangements, together with suitable electrical protection, conductor sizing and ventilation.
