Why Choose the ETE MV3000P2S1 Multi-Voltage Control Transformer?
The ETE MV3000P2S1 is a high-capacity 3000 VA single-phase multi-voltage control transformer designed to provide selectable 55 V AC or 110 V AC secondary outputs for industrial machinery, electrical control panels and automation systems. Part of the ETE MV range, it combines substantial power capacity with a versatile tapped-winding configuration for demanding industrial control applications.
Featuring 20/0/380/420 V primary terminals and 0/55/110 V secondary terminals, the MV3000P2S1 supports different nominal input and output voltage arrangements. Its secondary winding provides 55 V or 110 V output taps, making it suitable for equipment requiring either voltage. The primary winding also incorporates a 20 V adjustment tap; the correct connection arrangement must be confirmed with ETE before installation.
With Class E insulation, 3% voltage regulation and a specified EPN 5 enclosure reference, this transformer is suited to professionally designed industrial electrical installations. Its dimensions of 192 × 189 × 185 mm and weight of 28 kg should be considered when planning panel space, mechanical support and installation access.

High-Capacity 55 V and 110 V AC Power for Industrial Control Systems
The ETE MV3000P2S1 is designed for applications requiring an isolated AC supply with selectable 55 V and 110 V secondary voltage taps. Its 0/55/110 V secondary terminal arrangement allows the required nominal output voltage to be selected in accordance with the manufacturer's connection instructions. This flexibility is particularly useful for industrial machinery and electrical control systems incorporating different control voltage requirements.
The transformer's 3000 VA rating corresponds to a calculated nominal full-load secondary current of approximately 27.27 A at 110 V AC. The available loading on the 55 V tap, and any simultaneous loading arrangements, must be verified against ETE's winding and tapping instructions rather than assuming that the full rated power is available independently at every tap. Its specified 3% voltage regulation describes the change in secondary voltage between no-load and rated-load conditions.
Important connection note: The primary terminals are specified as 20/0/380/420 V, including a 20 V primary adjustment tap. Confirm the correct primary connections with ETE before energising the transformer. The equipment should be installed with suitable circuit protection, conductor sizing, mechanical support and ventilation according to the manufacturer's instructions and applicable electrical requirements.
