Why Choose the ETE WV3000P8S8 Wide-Input-Voltage Control Transformer?
The ETE WV3000P8S8 is a high-capacity 3000 VA (3 kVA) single-phase wide-input-voltage control transformer designed to provide reliable 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 high-voltage primary connections with configurable secondary windings, making it a practical solution for industrial control panel builders, OEM machinery manufacturers and electrical maintenance engineers.
The WV3000P8S8 features primary terminals marked 0/500/550/600/690 V, providing four nominal input voltage options for industrial electrical installations. Its dual 0/110/120 V 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 flexible arrangement enables the same transformer model to accommodate several industrial control voltage requirements while delivering a total rated apparent power of 3000 VA.
With Class E insulation and 3% voltage regulation, the ETE WV3000P8S8 offers substantial control power capacity, high-voltage input 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 combination of 500–690 V primary connections and configurable secondary voltages makes it particularly relevant to machinery and control systems operating from higher-voltage industrial supplies.

High-Capacity 110 V, 120 V, 220 V and 240 V AC Control Power from 500–690 V Industrial Supplies
The ETE WV3000P8S8 transforms a selected higher-voltage industrial AC input into a secondary supply suitable for compatible control equipment. Its four nominal primary voltage connections support installations using 500 V, 550 V, 600 V or 690 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 0/110/120 V. 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 WV3000P8S8 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 WV3000P8S8 is intended for integration into appropriately engineered industrial electrical installations. Suitable mechanical support is essential for a transformer of this weight. Because the primary connections include voltages up to 690 V AC, installation design must provide appropriate insulation clearances, circuit protection, earthing, conductor sizing, ventilation and safe access for inspection and maintenance. The required terminal connections and individual winding limits should be confirmed against ETE's installation documentation.
