Why Choose the ETE MV200P2S2 200 VA Multi-Voltage Control Transformer?
The ETE MV200P2S2 is a 200 VA single-phase multi-voltage control transformer designed for industrial electrical control panels, machinery and automation systems requiring a lower-voltage AC control supply from a higher-voltage primary source. Part of the ETE MV Multi-Voltage Series, it features 20/0/380/420 V primary terminals and 10/0/220/240 V secondary terminals, providing flexible voltage connection options for industrial control applications.
Manufactured by Eastern Transformers & Equipment (ETE), the MV200P2S2 is particularly suitable for electrical panel builders and OEM machinery manufacturers working with nominal 380 V or 420 V AC primary supplies and control equipment requiring a nominal 220 V or 240 V AC secondary connection. The precise input-to-output terminal combinations must be selected according to the manufacturer's connection diagram.
With a 200 VA rated capacity, Class E insulation and 10% voltage regulation, the transformer offers a practical solution for appropriately rated industrial control circuits. Its dimensions are 96 × 87 × 103 mm, its weight is 2.8 kg, and the specified enclosure references are EPH 2 or EPN 1.
Important connection note: The transformer incorporates adjustment tapping within its multi-voltage terminal arrangements. ETE specifies a 10 V adjustment tap that requires confirmation of the exact terminal connections. Do not assume the adjustment connections or voltage combinations without checking the manufacturer's wiring documentation.

Multi-Voltage Primary Connections for Industrial AC Supplies
The ETE MV200P2S2 incorporates a 20/0/380/420 V primary terminal arrangement, making it suitable for industrial control systems that require flexible primary voltage connections. The 380 V and 420 V terminal markings provide options for the manufacturer's specified supply arrangements.
This multi-voltage design is particularly useful for electrical panel builders and machinery manufacturers working with industrial AC distribution systems. Rather than requiring a different transformer model for every nominal supply arrangement, the MV200P2S2 provides a selection of primary terminal connections within a single transformer.
Installation requirement: The primary terminals must be connected according to the manufacturer's approved wiring diagram. The presence of the additional 20 V terminal does not establish an arbitrary adjustment method, and the relationship between the primary and secondary tapping arrangements should be verified before energisation.
Tapped 220 V and 240 V AC Secondary Connections
The MV200P2S2 features 10/0/220/240 V secondary terminals, providing a tapped secondary winding arrangement for industrial control applications. The manufacturer identifies the output configuration as a tapped output according to the datasheet, so the precise connections must be selected using ETE's approved terminal diagram.
For a nominal 220 V AC output, the transformer's 200 VA rating corresponds to a calculated secondary current of approximately 0.91 A. For a nominal 240 V AC output, the corresponding calculated current is approximately 0.83 A. These values are calculated from apparent power divided by nominal output voltage and assume the full rating is available at the selected output.
The 10 V adjustment terminal is an important feature of this secondary arrangement. However, the terminal marking alone does not establish how it should be combined with the other secondary connections. Confirm the exact 10 V adjustment tap connections with ETE before using this feature.
The specified 10% voltage regulation should also be considered when selecting contactors, relays and other voltage-sensitive equipment. The transformer must be sized for the connected load and any applicable switching inrush requirements.
Compact Construction for Industrial Control Panels
The ETE MV200P2S2 measures 96 mm in length, 87 mm in width and 103 mm in height, with a weight of 2.8 kg. These dimensions make it suitable for integration into appropriately designed electrical control cabinets, machinery panels and industrial switching assemblies.
ETE's MV transformer range incorporates IP20 touch-proof terminals, Class H varnish impregnation and a protective core earth connection. The range is designed to EN 61558-1, with continuous-rated operation and a specified ambient temperature range of −10 to +35 °C. The MV200P2S2 has Class E insulation.
The specified enclosure references for this model are EPH 2 or EPN 1. Installation should provide appropriate mounting support, ventilation, electrical protection, conductor sizing and protective earthing. All voltage tap connections should be verified against the manufacturer's documentation before commissioning.
