Why Choose the ETE MV1500P2S2 Multi-Voltage Control Transformer?
The ETE MV1500P2S2 is a robust 1500 VA (1.5 kVA) single-phase multi-voltage control transformer designed to provide reliable electrical isolation and adaptable 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 20/0/380/420 V and secondary terminals marked 10/0/220/240 V, providing flexible voltage connection options for compatible industrial installations.
Manufactured by Eastern Transformers & Equipment (ETE), the MV1500P2S2 incorporates nominal 380 V and 420 V primary connections and a tapped secondary winding arrangement with 220 V and 240 V terminals. The transformer also features a 10 V adjustment tap, for which the correct terminal connections must be confirmed with ETE. The primary terminal arrangement additionally includes a terminal marked 20 V, with the appropriate connections to be determined from the manufacturer's wiring information.
With a rated capacity of 1500 VA, Class E insulation and 4% voltage regulation, the MV1500P2S2 offers substantial control power capability for industrial applications. Measuring 150 × 151 × 145 mm and weighing 14.2 kg, it is suitable for integration into appropriately engineered electrical equipment. The manufacturer's specified enclosure reference is EPN 4.

Flexible Primary Connections for Industrial Electrical Supplies
The ETE MV1500P2S2 features primary terminals marked 20/0/380/420 V, providing nominal 380 V and 420 V connection options for compatible industrial power systems.
This arrangement is useful for electrical panel builders, OEM machinery manufacturers and control system integrators working with equipment designed for different nominal supply voltages. Selecting the appropriate primary connection helps match the transformer to the available electrical supply.
The primary terminal arrangement also includes a terminal marked 20 V. Its exact connection function must be established from ETE's wiring instructions rather than assumed from the terminal marking alone.
The transformer uses fixed winding connections rather than automatic voltage selection. The correct terminals must be identified before energising the equipment, with appropriate primary circuit protection and installation precautions.
Tapped 220 V and 240 V Secondary Connections
The MV1500P2S2 incorporates a tapped secondary winding with terminals marked 10/0/220/240 V. The manufacturer's specification identifies the output arrangement as tapped output per datasheet, allowing the correct secondary connection to be selected for the intended control circuit.
- 220 V terminal: Provides a nominal 220 V connection option when wired according to the manufacturer's instructions.
- 240 V terminal: Provides a nominal 240 V connection option when wired according to the manufacturer's instructions.
- 10 V adjustment tap: Provides an additional winding connection whose exact function and terminal arrangement must be confirmed with ETE.
The 10 V adjustment tap must not be assumed to provide an independent 10 V supply or a particular voltage correction without confirmation of the manufacturer's wiring arrangement. The correct output connections should be established from the relevant ETE datasheet before installation.
The 1500 VA rating applies to the transformer as a whole. Connected loads must remain within the applicable transformer and winding limits, with appropriate circuit protection, conductor sizing and consideration of equipment starting currents.
Reliable Industrial Control Power with 4% Voltage Regulation
The ETE MV1500P2S2 has a specified 4% voltage regulation, describing the change in secondary voltage between the manufacturer's defined loading conditions. This characteristic is useful when selecting a control transformer for industrial equipment where the connected electrical load may vary during operation.
Combined with its Class E insulation system, 1.5 kVA rated capacity and multi-voltage winding arrangement, the transformer provides a practical solution for industrial control applications requiring isolated AC power and selectable voltage connections.
