Why Choose the ETE WV750P7S8 Wide-Input-Voltage Control Transformer?
The ETE WV750P7S8 is a versatile 750 VA single-phase wide-input-voltage control transformer designed to provide dependable AC voltage transformation and electrical isolation for industrial machinery, electrical control panels and automation systems. Part of the ETE WV stock control transformer range, it combines multiple primary voltage connections with configurable secondary windings, making it a practical choice for control panel builders, OEM machine manufacturers and industrial maintenance engineers.
The WV750P7S8 features primary terminals marked 0/380/400/420/440/460/480 V, providing six nominal input voltage options for industrial electrical installations. Its dual 0/110/120 V secondary windings can be connected in parallel for 110 V or 120 V AC output, or in series for 220 V or 240 V AC output. This flexible arrangement allows one transformer model to accommodate several common industrial control voltage requirements.
With a rated capacity of 750 VA, Class E insulation and 4% voltage regulation, the ETE WV750P7S8 provides substantial control power capacity with relatively low specified voltage regulation. Measuring 150 × 108 × 145 mm and weighing 7.6 kg, it is suitable for integration into appropriately designed industrial electrical equipment, with an associated EPN 3 enclosure reference.

Flexible 110 V, 120 V, 220 V and 240 V AC Control Power for Industrial Automation
The ETE WV750P7S8 transforms a selected industrial AC input voltage into a secondary supply suitable for compatible control equipment. Its six nominal primary voltage connections support installations using 380 V, 400 V, 420 V, 440 V, 460 V or 480 V AC supplies. This flexibility can simplify transformer selection across machinery and electrical installations with different nominal supply voltages, provided the correct primary terminal is selected.
On the secondary side, the transformer incorporates two separate windings, each marked 0/110/120 V. When correctly connected in parallel, corresponding winding taps provide a 110 V or 120 V AC supply. When connected in an additive series arrangement, they provide 220 V or 240 V AC. Parallel connections require matching voltage taps and winding polarity, while series connections must use the correct additive polarity arrangement. All connections must follow ETE's terminal identification and wiring instructions.
The transformer's 750 VA capacity is the total rated apparent power, not a separate 750 VA allowance for each secondary winding. This capacity can support one or more compatible control loads, provided their combined operating and starting demands remain within the permitted transformer and winding ratings. Its specified 4% voltage regulation should be considered when selecting connected equipment, particularly where voltage tolerance is important.
With Class E insulation, dimensions of 150 × 108 × 145 mm and a 7.6 kg weight, the WV750P7S8 is suited to appropriately supported industrial control panel installations. The associated EPN 3 enclosure reference identifies the manufacturer's enclosure option. Installation design should account for adequate mechanical support, ventilation, electrical protection, earthing and safe access to terminals.
