Why Choose the ETE MV1500P3S3 1500 VA Control Transformer?
The ETE MV1500P3S3 is a robust and versatile 1500 VA (1.5 kVA) single-phase control transformer designed to provide reliable low-voltage AC power for industrial control circuits, electrical panels and automation equipment. Part of the ETE MV multi-voltage control transformer series, it features dual primary and dual secondary windings, allowing flexible series or parallel connections to accommodate different supply and output voltage requirements.
The MV1500P3S3 incorporates two 120 V AC primary windings with terminals marked 0/120 V + 0/120 V. These windings can be connected in parallel for a 120 V AC single-phase supply or in series for a 240 V AC single-phase supply. On the secondary side, two independent 12 V AC windings can be connected in parallel to provide 12 V AC or in series to provide 24 V AC, making the transformer suitable for a wide range of industrial control applications.
With a rated apparent power of 1500 VA, Class E insulation and 4% voltage regulation, the ETE MV1500P3S3 provides dependable voltage conversion for demanding industrial installations. Its compact 150 × 151 × 145 mm construction, 14.2 kg weight and specified EPN 4 enclosure compatibility make it a practical solution for electrical panel builders, OEM machine manufacturers and industrial automation engineers.

The ETE MV1500P3S3 control transformer uses electromagnetic induction to convert a higher single-phase AC supply voltage into a lower AC voltage suitable for industrial control and auxiliary equipment. Its dual primary winding design allows the same transformer to operate from either a 120 V AC or 240 V AC supply, depending on the selected primary connection arrangement.
The transformer incorporates two independent 120 V AC primary windings. For a 120 V AC supply, the primary windings are connected in parallel with the correct polarity, allowing both windings to share the input load. For a 240 V AC supply, the windings are connected in series with the correct polarity so that the applied voltage is divided between them. This flexible configuration makes the MV1500P3S3 suitable for industrial installations using either supported supply voltage.
On the secondary side, the transformer features two independent 12 V AC windings. Connecting these windings in parallel with the correct polarity provides a nominal 12 V AC output, while connecting them in series with the correct polarity provides a nominal 24 V AC output. Both configurations are based on the transformer's total 1500 VA apparent power rating.
At the full 1500 VA rating, the theoretical secondary output currents are 125 A at 12 V AC and 62.5 A at 24 V AC. These values are calculated from apparent power and nominal voltage rather than independently confirmed terminal current ratings. The actual permissible load must remain within ETE's specified winding, connection and terminal limits.
With Class E insulation and 4% voltage regulation, the MV1500P3S3 provides a practical solution for industrial electrical installations requiring flexible low-voltage AC power. Its compact construction supports integration into appropriately designed control panels and machinery cabinets, while the specified EPN 4 enclosure provides a compatible housing option. Correct winding polarity, series or parallel connections, protective devices and earthing arrangements must be established in accordance with the manufacturer's installation instructions.
