The ETE WV300P7S8 is a versatile 300 VA single-phase wide-input-voltage control transformer designed for dependable AC voltage transformation in 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 WV300P7S8 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 300 VA, Class E insulation and 8% voltage regulation, the ETE WV300P7S8 offers a balance of electrical capacity, voltage flexibility and compact construction. Measuring 120 × 100 × 120 mm and weighing 4.7 kg, it is suitable for installation in appropriately designed industrial electrical equipment, with associated EPH 3 or EPN 2 enclosure references.
The ETE WV300P7S8 is designed to transform a selected industrial AC input voltage into a suitable secondary supply for compatible control equipment. Its six nominal primary voltage connections make it useful in installations operating at different supply voltages, including 380 V, 400 V, 420 V, 440 V, 460 V and 480 V AC. The correct primary terminal must be selected to match the available supply and the manufacturer's wiring instructions.
On the secondary side, the transformer incorporates two windings, each marked 0/110/120 V. When correctly connected in parallel, the 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; series connections must also follow the correct polarity arrangement. All terminal wiring should be completed in accordance with ETE's instructions.
The transformer's 300 VA capacity is the total rated apparent power, not a separate 300 VA allowance for each secondary winding. This makes it suitable for supplying one or more compatible control loads, provided their combined continuous and starting requirements remain within the transformer's permitted ratings. Its specified 8% voltage regulation should be considered when selecting connected equipment, particularly where voltage tolerance is important.
With Class E insulation, a compact footprint and a 4.7 kg weight, the WV300P7S8 is suited to appropriately supported industrial control panel installations. The associated EPH 3 or EPN 2 enclosure references help identify suitable manufacturer enclosure options. Installation design should also account for electrical protection, ventilation, earthing, safe access and secure mounting.

The ETE WV300P7S8 is a 300 VA single-phase wide-input-voltage control transformer designed to provide isolated AC supplies for industrial machinery, control panels and compatible automation equipment. Its secondary windings support 110 V, 120 V, 220 V or 240 V AC output configurations.
The transformer has a total rated apparent power of 300 VA. This is the overall transformer capacity and must not be interpreted as 300 VA available independently from each secondary winding.
Its primary terminals are marked 0/380/400/420/440/460/480 V, providing nominal input voltage options of 380 V, 400 V, 420 V, 440 V, 460 V and 480 V AC.
The transformer has dual 0/110/120 V secondary windings. They can be connected in parallel for 110 V or 120 V AC, or in series for 220 V or 240 V AC, using the appropriate winding connections.
For 110 V or 120 V AC, the corresponding secondary taps are connected in parallel with matching polarity. For 220 V or 240 V AC, the corresponding windings are connected in series with additive polarity. Connections must follow ETE's terminal identification and wiring instructions.
The ETE WV300P7S8 has Class E insulation, providing a defined thermal insulation classification for operation within the manufacturer's specified limits.
The transformer has 8% voltage regulation. This should be considered when choosing connected equipment because secondary voltage can vary between no-load and rated-load conditions.
The transformer measures 120 × 100 × 120 mm (length × width × height) and weighs 4.7 kg.
The specified enclosure references are EPH 3 or EPN 2. The appropriate option should be selected according to the installation's protection, ventilation, mounting and wiring requirements.
Yes. Its 300 VA total rated capacity can support multiple compatible devices, provided their combined apparent power, starting demands and operating requirements remain within the transformer's overall and individual winding limits.
The ETE WV300P7S8 combines 300 VA capacity, six nominal primary voltage options and configurable dual 110/120 V secondary windings in a compact industrial transformer. With 110/120 V parallel or 220/240 V series output, Class E insulation and 8% voltage regulation, it provides a flexible solution for compatible industrial control and auxiliary power applications.
