ETE MV1000P2S1 Multi-Voltage Control Transformer 1000VA 20/0/380/420V to 0/55/110V

Why Choose the ETE MV1000P2S1 1000 VA Multi-Voltage Control Transformer?

The ETE MV1000P2S1 is a high-capacity 1000 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 nominal 55 V AC or 110 V AC connections for compatible industrial control equipment.

With a rated apparent power of 1000 VA (1 kVA), the MV1000P2S1 is particularly suitable for control circuits with substantial aggregate electrical loads, including installations containing multiple contactors, electromagnetic relays, signalling devices and AC-operated actuators. Its higher power capacity makes it a practical choice for industrial machinery and electrical control systems where smaller transformers may not provide sufficient apparent power.

The primary winding incorporates terminals marked 380 V and 420 V, together with a 20 V primary adjustment tap. This arrangement provides connection flexibility for compatible industrial AC supplies. However, the precise function of the adjustment tap and the permitted primary terminal combinations must be confirmed with ETE before installation.

On the secondary side, the 0/55/110 V tapped winding provides nominal 55 V AC or 110 V AC output connections. This enables the transformer to be specified for different control voltage requirements, subject to the manufacturer's approved connection arrangements and individual tap loading limits.

Featuring Class E insulation and 4% voltage regulation, the MV1000P2S1 offers defined electrical characteristics for industrial transformer selection. Its dimensions of 150 × 125 × 145 mm and weight of 9.8 kg support installation within appropriately designed electrical cabinets. The specified compatible enclosure reference is ETE EPN 3.

Reliable 1 kVA Control Power with Selectable 55 V or 110 V AC Outputs

The ETE MV1000P2S1 provides a high-capacity solution for industrial electrical installations requiring selectable 55 V AC or 110 V AC control voltage. Its 20/0/380/420 V primary arrangement and 0/55/110 V secondary winding make it suitable for control panel designs where industrial AC supply voltages must be transformed to compatible lower-voltage control circuits.

The primary winding includes terminals marked 380 V and 420 V, together with a 20 V adjustment tap. These markings identify available winding connections but do not independently establish every permissible supply voltage arrangement. The adjustment tap should not be treated as a standalone 20 V supply input. The correct primary terminal combinations must be verified using ETE's approved connection information before the transformer is energised.

The secondary winding incorporates an intermediate 55 V tap and a full 110 V connection. This provides nominal secondary voltage options for compatible industrial control equipment. Where the transformer is being considered for a centre-tapped 110 V control circuit, the intended connection arrangement and any centre-point earthing requirements should be verified against the manufacturer's documentation.

With a rated apparent power of 1000 VA, the MV1000P2S1 provides a calculated nominal full-load current of approximately 9.09 A at 110 V AC. This value is derived by dividing the transformer rating by the nominal full secondary voltage. The permissible current through the intermediate 55 V winding section has not been specified separately and must be confirmed with ETE before applying a substantial load to that tap.

The specified 4% voltage regulation is relevant to industrial control circuits containing electromagnetic devices and other loads that can produce changes in secondary voltage as their operating state changes. Contactors, relays and solenoids may draw greater apparent power during energisation than during normal operation. Electrical designers should therefore consider steady-state loading, simultaneous switching demands and the voltage tolerances of connected equipment.

Compared with lower-rated transformers in the same product family, the 1 kVA capacity makes the MV1000P2S1 particularly relevant to installations with multiple compatible AC control components. The total connected apparent power, winding-specific limits and required operating margins should be evaluated when determining whether the transformer is appropriately sized.

The MV1000P2S1 features Class E insulation, dimensions of 150 × 125 × 145 mm and a weight of 9.8 kg. These characteristics should be considered when selecting mounting arrangements, mechanical supports and enclosure space. The specified compatible enclosure reference is ETE EPN 3.

The transformer provides AC voltage transformation rather than regulated DC output. Equipment requiring DC control voltage will need suitable additional conversion components. Installation should account for correct primary tap selection, suitable primary and secondary circuit protection, conductor sizing, secure mounting, ventilation and protective earthing where applicable.
