Why Choose the ETE MV6250P1S1 6250 VA Multi-Voltage Control Transformer?

The ETE MV6250P1S1 is a high-capacity 6250 VA (6.25 kVA) single-phase multi-voltage control transformer designed for industrial electrical control systems, machinery 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.

The MV6250P1S1 features a 10/0/220/240 V primary terminal arrangement for compatible 220 V and 240 V AC supplies. Its 0/55/110 V secondary terminals provide selectable 55 V or 110 V AC outputs, allowing the transformer to serve different industrial control voltage requirements. A 10 V primary adjustment tap is also provided, with the correct connections to be confirmed with ETE.

With a substantial 6250 VA power rating, Class F insulation and 3% voltage regulation, this transformer is suitable for demanding industrial installations. Measuring 245 × 250 × 230 mm and weighing 58 kg, it requires suitable mechanical support and installation space. The specified protective enclosure reference is EPN 7.

High-Capacity 55 V and 110 V AC Control Power

Industrial control transformers provide voltage conversion and electrical isolation for control circuits and compatible electrical equipment. The ETE MV6250P1S1 is designed to operate from suitable 220 V or 240 V AC primary supplies and deliver a selectable 55 V or 110 V AC secondary output.

The transformer uses a 0/55/110 V tapped secondary winding, allowing the required voltage to be selected through the appropriate terminals. The 10/0/220/240 V primary arrangement also incorporates a 10 V adjustment tap. Correct primary and secondary connections must follow ETE's instructions, particularly when selecting adjustment taps.

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, but the actual permissible loading of the 55 V tap must be verified with ETE. A tapped winding must not automatically be assumed to provide the full transformer rating at every voltage selection.

The transformer's 3% voltage regulation and Class F insulation support dependable industrial performance. Its 58 kg weight requires appropriately rated mounting arrangements and safe handling procedures, together with suitable electrical protection, ventilation and conductor sizing.
