Why Choose the ETE MV200P1S1 200 VA Multi-Voltage Control Transformer?
The ETE MV200P1S1 is a 200 VA single-phase multi-voltage control transformer designed to provide reliable AC control power for industrial machinery, electrical control panels and automation equipment. Part of the ETE MV Multi-Voltage Series, it features 10/0/220/240 V primary terminals and 0/55/110 V secondary terminals, providing selectable nominal 55 V AC or 110 V AC output connections.
Manufactured by Eastern Transformers & Equipment (ETE), the MV200P1S1 is intended for industrial applications requiring flexible transformer voltage connections. Its secondary winding is also identified as 55/0/55 V, providing a 110 V AC winding with a 55 V centre tap. This arrangement is particularly useful in appropriately designed industrial control systems requiring 110 V AC or centre-tapped 55-0-55 V supplies.
With a 200 VA rated capacity, Class E insulation and 10% voltage regulation, the transformer provides a practical solution for industrial control circuit power distribution. Its dimensions are 96 × 87 × 103 mm, with a weight of 2.8 kg. The specified enclosure references are EPH 2 or EPN 1.
Important installation note: The primary winding includes a 10 V adjustment tap. The exact terminal connections and intended adjustment arrangement must be confirmed with ETE before installation or energisation.

Flexible 220 V and 240 V Primary Connections
The ETE MV200P1S1 multi-voltage transformer incorporates a 10/0/220/240 V primary terminal arrangement, providing connection options for industrial installations with nominal 220 V AC or 240 V AC supplies. This flexibility makes the transformer useful for electrical panel builders, OEM machinery manufacturers and maintenance engineers working with different control supply requirements.
The primary winding includes a 10 V adjustment tap. This terminal arrangement must be interpreted using the manufacturer's wiring instructions, as the adjustment connection cannot be determined safely from the terminal markings alone.
Connection requirement: Confirm the correct primary terminal arrangement and the intended use of the 10 V adjustment tap with ETE before energising the transformer. The selected connections must match the available supply voltage and the manufacturer's approved configuration.
55 V and 110 V AC Secondary Connections with Centre Tap
The MV200P1S1 features a 0/55/110 V secondary terminal arrangement, corresponding to the manufacturer's 55/0/55 V centre-tapped winding. This allows the transformer to provide a nominal 110 V AC output across the complete secondary winding or a nominal 55 V AC output between the appropriate centre-tap and outer terminal.
For applications using the complete 110 V secondary winding, the 200 VA rating corresponds to a calculated nominal current of approximately 1.82 A. This is useful when selecting appropriately rated industrial control equipment, including contactors, relays and switching circuits.
For a 55 V output connection, dividing the total transformer rating by 55 V gives a theoretical current of approximately 3.64 A. However, this calculation does not establish the permissible current of an individual half-winding. The allowable 55 V tap loading must be confirmed with ETE before designing a circuit around that current.
The centre-tapped winding arrangement may also be useful in control systems requiring a 55-0-55 V supply. Any centre-tap earthing, secondary circuit protection or simultaneous loading arrangement should follow the manufacturer's guidance and the requirements of the complete electrical installation.
Industrial Construction and Installation Considerations
The ETE MV200P1S1 measures 96 mm in length, 87 mm in width and 103 mm in height, with a weight of 2.8 kg. These dimensions allow it to be incorporated into appropriately designed industrial electrical cabinets and machinery control panels.
ETE specifies Class E insulation, Class H varnish impregnation, IP20 touch-proof terminals and a protective core earth connection. The transformer is designed to EN 61558-1 for continuous-rated control circuit operation, with a specified ambient temperature range of −10 to +35 °C.
The manufacturer's enclosure references for this model are EPH 2 or EPN 1. The final installation should provide suitable mechanical support, ventilation, electrical protection, conductor sizing and protective earthing. Transformer selection should also account for steady-state load, contactor inrush requirements and the specified 10% voltage regulation.
