Why Choose the ETE MV1000P1S1 Multi-Voltage Control Transformer?
The ETE MV1000P1S1 is a robust 1000 VA (1 kVA) single-phase multi-voltage control transformer designed to provide reliable electrical isolation and selectable AC control voltages 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, allowing the selection of nominal 55 V AC or 110 V AC output connections.
Manufactured by Eastern Transformers & Equipment (ETE), the MV1000P1S1 is suitable for industrial installations requiring a dedicated control transformer with flexible primary voltage connections. Its primary winding incorporates nominal 220 V and 240 V connections, together with a 10 V primary adjustment tap whose correct terminal arrangement must be confirmed with ETE before installation.
With a rated capacity of 1000 VA, Class E insulation and 4% voltage regulation, the MV1000P1S1 combines substantial control power capability with practical voltage selection. Measuring 150 × 125 × 145 mm and weighing 9.8 kg, it is designed for integration into appropriately engineered industrial electrical equipment. The specified enclosure reference is EPN 3.

Flexible Primary Voltage Connections for Industrial Control Systems
The ETE MV1000P1S1 features primary terminals marked 10/0/220/240 V, providing nominal 220 V and 240 V primary connection options alongside a 10 V adjustment tap.
This configuration makes the transformer suitable for electrical control systems where the available nominal supply voltage must be matched to the transformer connection. The appropriate primary terminals should be selected according to the supply voltage and the manufacturer's connection documentation.
The 10 V primary adjustment tap provides additional connection flexibility. However, the precise use of this adjustment tap and its relationship to the other primary terminals must be confirmed with ETE. It should not be treated as an independent 10 V output or connected on the basis of assumed terminal relationships.
The primary terminals are fixed winding connections rather than an automatic voltage-ranging input. All connections must be verified before the transformer is energised.
Selectable 55 V AC or 110 V AC Secondary Output
The MV1000P1S1 has secondary terminals marked 0/55/110 V, allowing the installer to select the required nominal secondary voltage 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.
Unlike transformers with two separately specified secondary windings, the MV1000P1S1 is described with a single tapped secondary terminal arrangement. The 55 V and 110 V connections should therefore be selected according to ETE's wiring documentation rather than treated as independent outputs with separate full-power ratings.
The 1000 VA rating applies to the transformer as a whole. Connected loads must remain within the applicable transformer and winding limits, with suitable circuit protection and conductor sizing.
Reliable Industrial Control Power with 4% Voltage Regulation
The ETE MV1000P1S1 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 transformer for control circuits where load demand may vary during operation.
Combined with its Class E insulation system, 1 kVA capacity and selectable secondary voltage taps, the transformer provides a practical solution for industrial electrical installations requiring isolated AC control power.
