Why Choose the ETE MV4000P1S1 Multi-Voltage Control Transformer?
The ETE MV4000P1S1 is a high-capacity 4000 VA (4 kVA) single-phase multi-voltage control transformer designed to provide dependable electrical isolation and selectable AC control power for industrial machinery, electrical control panels and automation systems. Part of the ETE MV Multi-Voltage transformer series, it features primary terminals marked 10/0/220/240 V and secondary terminals marked 0/55/110 V, providing flexible voltage connections for demanding industrial applications.
The MV4000P1S1 incorporates nominal 220 V and 240 V primary connections and selectable 55 V AC or 110 V AC secondary output taps. Its primary winding also includes a 10 V adjustment tap, with the correct terminal connections requiring confirmation from ETE before installation. This combination makes the transformer suitable for industrial equipment requiring substantial control power capacity and adaptable voltage arrangements.
With a rated capacity of 4000 VA, Class F insulation and 3% voltage regulation, the ETE MV4000P1S1 provides a practical solution for industrial control systems where dependable secondary voltage performance is important. Measuring 245 × 190 × 230 mm and weighing 36 kg, the transformer is intended for integration into appropriately engineered electrical equipment. The manufacturer's specified enclosure reference is EPN 6.

Flexible 220 V and 240 V Primary Connections
The ETE MV4000P1S1 features primary terminals marked 10/0/220/240 V, incorporating nominal 220 V and 240 V connections for compatible industrial electrical supplies.
This arrangement provides useful flexibility for electrical panel builders, machinery manufacturers and control system integrators working with equipment designed for different nominal supply voltages. Selecting the appropriate primary winding connection allows the transformer to be matched to the intended installation.
The primary terminal arrangement also incorporates a 10 V adjustment tap. The exact function and correct connection of this tap must be confirmed with ETE. It should not be assumed to provide an independent 10 V supply or a particular voltage correction without reference to the manufacturer's wiring documentation.
The primary terminals are fixed winding connections rather than an automatic voltage-ranging input. The correct connections must be verified before energising the transformer, with suitable primary circuit protection and installation precautions.
Selectable 55 V AC or 110 V AC Secondary Output
The MV4000P1S1 incorporates a tapped secondary winding arrangement with terminals marked 0/55/110 V. These terminals provide selectable nominal secondary voltage connections for compatible industrial control equipment.
- 55 V AC output: The appropriate secondary tap provides a nominal 55 V AC supply for compatible control circuits.
- 110 V AC output: The appropriate secondary tap provides a nominal 110 V AC supply for compatible industrial control equipment.
The manufacturer specifies 55 V or 110 V tapped output connections, rather than two independently rated secondary windings. The correct output should therefore be selected according to ETE's wiring documentation, without assuming that both voltage connections provide separate full-capacity supplies.
The 4000 VA rating applies to the transformer as a whole. Connected loads must remain within the applicable transformer and winding limits, with appropriate conductor sizing, circuit protection and consideration of equipment starting currents.
Dependable Control Power with 3% Voltage Regulation
The ETE MV4000P1S1 has a specified 3% voltage regulation, describing the change in secondary voltage between the manufacturer's defined loading conditions. This characteristic is useful when selecting a transformer for industrial control circuits where the electrical load may vary during operation.
Combined with its substantial 4 kVA capacity and Class F insulation system, the MV4000P1S1 provides a practical solution for industrial applications requiring isolated AC control power and selectable secondary voltage taps.
Class F Insulation for Industrial Transformer Applications
The MV4000P1S1 features a Class F insulation system, providing a recognised thermal classification for the transformer's insulation materials. This is particularly relevant for industrial control transformers where electrical loading and operating conditions must be considered during equipment design.
Class F insulation is associated with a 155 °C thermal classification under applicable insulation system standards. This classification does not represent a permitted ambient operating temperature or guarantee a particular transformer temperature rise. Installation conditions, ventilation and loading must remain within the manufacturer's requirements.
