Why Choose the ETE WV1000P8S8 1000 VA Wide-Input-Voltage Control Transformer?
The ETE WV1000P8S8 is a versatile 1000 VA (1 kVA) single-phase wide-input-voltage control transformer designed for industrial electrical control panels, machinery, switchgear and automation systems. Part of the ETE WV wide-input-voltage control transformer range, it combines multiple high-voltage primary taps with configurable dual secondary windings, providing flexible AC voltage conversion for industrial installations requiring a higher-capacity control power supply.
The WV1000P8S8 features a 0/500/550/600/690 V primary terminal arrangement, supporting compatible 500, 550, 600 and 690 V AC supplies. Its two 0/110/120 V secondary windings can be connected in parallel for 110 V or 120 V AC, or in series for 220 V or 240 V AC. This flexibility makes the transformer suitable for industrial control equipment with different operating voltage requirements.
With a rated apparent power of 1000 VA (1 kVA), Class E insulation and 4% voltage regulation, the WV1000P8S8 provides a practical solution for appropriately rated industrial control circuits. Its dimensions of 150 × 125 × 145 mm and weight of 9.8 kg make it suitable for installation in electrical control cabinets with adequate mounting space and mechanical support. The specified enclosure reference is EPN 3.

The ETE WV1000P8S8 is designed for industrial control installations where the available primary supply voltage may differ between machines, facilities or electrical systems. Its selectable primary terminals support 500, 550, 600 and 690 V AC, allowing the transformer to be configured for several compatible industrial electrical supplies.
The transformer incorporates two secondary windings, each with 0/110/120 V terminals. Connecting matching secondary winding taps in parallel with the correct polarity provides 110 V or 120 V AC. Connecting the windings in series with the correct additive polarity provides 220 V or 240 V AC. All winding connections must follow ETE's instructions to ensure correct voltage selection and safe operation.
Based on its 1000 VA rating, the theoretical full-load secondary current is approximately 9.09 A at 110 V AC, 8.33 A at 120 V AC, 4.55 A at 220 V AC or 4.17 A at 240 V AC. These calculated values assume the full rated apparent power is available in the selected configuration. Actual permissible winding currents and loading requirements must follow ETE's specifications.
The specified 4% voltage regulation means secondary voltage variation between operating load conditions should be considered when selecting connected equipment. Sensitive devices requiring tightly regulated supplies may need additional voltage regulation. Correct primary tap selection, secondary winding polarity, suitable circuit protection, conductor sizing and appropriate installation clearances are particularly important when working with primary supplies up to 690 V AC.
