Why Choose the ETE MV200P2S1 200 VA Multi-Voltage Control Transformer?
The ETE MV200P2S1 is a versatile 200 VA single-phase multi-voltage control transformer designed for industrial electrical control panels, machinery and automation systems requiring reliable AC voltage transformation. Part of the ETE MV multi-voltage control transformer range, this model features 20/0/380/420 V primary terminals and 0/55/110 V secondary terminals, providing selectable 55 V AC or 110 V AC output connections for compatible industrial control equipment.
The MV200P2S1 is particularly useful for installations involving industrial AC supplies where different control voltage requirements must be accommodated. Its primary winding incorporates terminals marked 380 V and 420 V, together with a 20 V primary adjustment tap. This additional connection provides voltage adjustment flexibility, although the exact permitted terminal combinations must be confirmed with ETE before installation.
On the secondary side, the 0/55/110 V tapped winding allows the transformer to supply nominal 55 V AC or 110 V AC, depending on the selected connections. This arrangement makes the MV200P2S1 suitable for appropriately rated contactor coils, electromagnetic relays, signalling devices, solenoids and other industrial AC control components.
With a rated apparent power of 200 VA, Class E insulation and 10% voltage regulation, the MV200P2S1 offers a practical combination of output capacity and connection flexibility. Measuring 96 × 87 × 103 mm and weighing 2.8 kg, it is suitable for integration into industrial electrical cabinets. The specified compatible enclosure references are ETE EPH 2 or EPN 1.

Reliable 55 V or 110 V AC Control Power for Industrial Applications
The ETE MV200P2S1 provides a practical solution for industrial electrical installations requiring a choice of 55 V AC or 110 V AC control voltage. Its 20/0/380/420 V primary terminal arrangement and 0/55/110 V secondary winding make it suitable for control panel designs where the available supply and required control voltage must be considered together.
The primary winding includes connections marked 380 V and 420 V, together with a 20 V adjustment tap. This additional connection must not be interpreted as a standalone 20 V supply input. The exact function of the adjustment tap, permitted terminal combinations and appropriate connection for the available supply should be confirmed against ETE's approved wiring information before the transformer is energised.
The secondary winding provides nominal 55 V AC and 110 V AC connection options. The intermediate 55 V tap can be used for compatible lower-voltage control equipment, while the full 110 V connection provides the higher nominal secondary voltage. Where an application requires a centre-tapped 110 V supply, the appropriate terminal and earthing arrangement must be verified rather than assumed solely from the terminal markings.
The 200 VA apparent power rating corresponds to a calculated nominal full-load secondary current of approximately 1.82 A at 110 V AC. Dividing the same apparent power by 55 V gives a theoretical current equivalent of approximately 3.64 A. However, this calculation does not independently establish the permissible current through the individual 55 V winding section. The manufacturer's tap-specific current limits must be confirmed before applying the full transformer rating to an intermediate secondary connection.
The specified 10% voltage regulation is important when selecting industrial control components that must operate reliably under varying load conditions. Secondary voltage may change as connected equipment switches on or off, particularly where electromagnetic devices such as contactors, relays and solenoids have a higher initial energisation demand than their normal operating consumption. Designers should consider both steady-state apparent power and simultaneous switching requirements.
With Class E insulation, compact dimensions of 96 × 87 × 103 mm and a weight of 2.8 kg, the MV200P2S1 is suited to appropriately designed industrial electrical cabinets. The specified EPH 2 or EPN 1 enclosure references provide compatible housing options where additional physical protection is required.
The MV200P2S1 provides AC voltage transformation and does not incorporate a rectifier or regulated DC output stage. Equipment requiring DC control voltage will need suitable additional power conversion components. Correct primary tap selection, secondary connections, circuit protection, conductor sizing, protective earthing where applicable and adequate ventilation should be considered during installation.
