Why Choose the ETE WV3000P7S8 Wide-Input-Voltage Control Transformer?
The ETE WV3000P7S8 is a high-capacity 3000 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 substantial apparent power capacity with multiple primary voltage connections and configurable secondary windings, making it a practical choice for industrial control panel builders, OEM machinery manufacturers and electrical maintenance engineers.
The WV3000P7S8 features primary terminals marked 0/380/400/420/440/460/480V, providing six nominal input voltage options for industrial electrical installations. Its dual 0/110/120V secondary windings can be connected in parallel to provide 110 V or 120 V AC, or in series to provide 220 V or 240 V AC. This configurable arrangement enables the same transformer model to accommodate several common industrial control voltage requirements while delivering a total rated apparent power of 3000 VA (3 kVA).
With Class E insulation and 3% voltage regulation, the ETE WV3000P7S8 offers a combination of high control power capacity, input voltage flexibility and relatively low specified voltage regulation. Measuring 192 × 189 × 185 mm and weighing 28 kg, it is intended for integration into appropriately engineered industrial electrical installations, with an associated EPN 5 enclosure reference. Its 3000 VA capacity makes it particularly suitable for control systems with substantial combined auxiliary AC power requirements.

High-Capacity 110 V, 120 V, 220 V and 240 V AC Control Power for Industrial Automation
The ETE WV3000P7S8 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. The correct primary terminal must be selected to match the available supply and connected in accordance with ETE's instructions.
On the secondary side, the transformer incorporates two separate windings, each marked 0/110/120V. When correctly connected in parallel, corresponding winding taps provide 110 V or 120 V AC. When connected in series with additive polarity, 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. Incorrect connections can cause damaging circulating currents or an unsuitable output voltage, so the manufacturer's terminal identification and wiring instructions must be followed before energising the transformer.
The 3000 VA (3 kVA) rating represents the transformer's total rated apparent power, rather than a separate 3000 VA allowance for each secondary winding. This capacity makes the WV3000P7S8 relevant to industrial control systems with substantial combined AC power demands, provided connected equipment remains within the transformer's permitted continuous and starting-load ratings. Its specified 3% voltage regulation should also be considered when selecting voltage-sensitive control equipment, as the secondary voltage can vary with loading.
With Class E insulation, a 28 kg weight and an associated EPN 5 enclosure reference, the WV3000P7S8 is intended for integration into appropriately engineered industrial electrical installations. Suitable mechanical support is essential for a transformer of this weight. The installation should also incorporate appropriate circuit protection, ventilation, earthing, conductor sizing and safe access for inspection and maintenance. The required terminal connections, protective device selection and individual winding limits should be confirmed against ETE's installation documentation.
