Why Choose the ETE MV200P1S3 200 VA Multi-Voltage Control Transformer?
The ETE MV200P1S3 is a versatile 200 VA single-phase multi-voltage control transformer designed for industrial electrical control panels, machinery and automation systems requiring flexible AC control voltage arrangements. Part of the ETE MV multi-voltage control transformer range, this model features 10/0/220/240 V primary terminals and two separate 0/12 V secondary windings, allowing the secondary outputs to be configured for 12 V AC parallel operation or 24 V AC series operation.
The MV200P1S3 is particularly useful for industrial installations where different low-voltage AC control requirements must be accommodated without changing the transformer model. Its dual secondary windings provide flexibility for supplying compatible relays, contactors, signalling devices, solenoid valves and other industrial control components. When correctly connected in parallel, the two secondary windings provide a nominal 12 V AC output; when connected in series with the correct winding polarity, they provide a nominal 24 V AC output.
The primary winding incorporates terminals marked 10/0/220/240 V, including a 10 V primary adjustment tap. The precise connection arrangement for this adjustment tap must be confirmed with ETE before installation. Correct terminal selection is essential to ensure the intended secondary voltage and safe transformer operation.
With a rated apparent power of 200 VA, Class E insulation and 10% voltage regulation, the MV200P1S3 provides practical voltage transformation for industrial control applications. Measuring 96 × 87 × 103 mm and weighing 2.8 kg, it is suitable for integration into electrical control cabinets. The specified compatible enclosure references are ETE EPH 2 or EPN 1.

Reliable 12 V or 24 V AC Control Power with Dual Secondary Windings
The ETE MV200P1S3 is designed for industrial electrical control systems requiring a choice between 12 V AC and 24 V AC without changing the transformer itself. Its two separate 0/12 V secondary windings can be configured in parallel or series, providing useful flexibility for control panel manufacturers, machinery builders and maintenance engineers.
In the parallel configuration, the two 12 V secondary windings are connected with matching polarity to provide a nominal 12 V AC output. This arrangement is intended to combine the available current capacity of the two windings. Parallel connection must follow ETE's approved wiring diagram because incorrect polarity can create a damaging circulating current or an effective short circuit.
In the series configuration, the two 12 V windings are connected in the correct additive polarity to provide a nominal 24 V AC output. Incorrect series polarity can result in the winding voltages opposing each other rather than adding together. The correct terminal connections must therefore be verified before the transformer is energised.
The 200 VA apparent power rating gives a theoretical nominal output current of approximately 8.33 A at 24 V AC or 16.67 A at 12 V AC, assuming the full transformer rating is available in the relevant manufacturer-approved configuration. These figures are calculated from apparent power divided by output voltage and should not be treated as independently verified winding current ratings. The permissible current of each individual 12 V winding and the total allowable load must be confirmed from ETE's technical documentation.
The primary winding is marked 10/0/220/240 V and includes a 10 V adjustment tap. The terminal arrangement provides flexibility for compatible industrial AC supplies, but the adjustment tap must not be wired by assumption. Its exact purpose and permitted connection combinations should be confirmed directly with ETE or through the manufacturer's approved connection diagram.
The specified 10% voltage regulation is relevant when selecting equipment that must operate reliably across varying control circuit loads. Electromagnetic devices such as contactors, relays and solenoids may draw higher apparent power during initial energisation than during normal operation. The total connected load, simultaneous switching requirements and operating voltage tolerances should be assessed before selecting the transformer for a particular application.
With Class E insulation, a compact 96 × 87 × 103 mm construction and a weight of 2.8 kg, the MV200P1S3 is suitable for integration into appropriately designed industrial control cabinets. The specified EPH 2 or EPN 1 enclosure references offer compatible housing options where additional physical protection is required.
The MV200P1S3 supplies AC output and does not incorporate a rectifier or regulated DC power supply. Where connected equipment requires 12 V DC or 24 V DC, appropriate additional conversion equipment must be provided. Installation should include suitable primary and secondary circuit protection, protective earthing where required, conductor sizing, mounting and ventilation.
