The ETE WV100P8S8 is a compact and versatile 100 VA single-phase wide-input-voltage control transformer designed to provide reliable voltage transformation for industrial control circuits, electrical panels and automation equipment. As part of the ETE WV wide-input-voltage control transformer series, it is particularly suitable for panel builders, OEM machinery manufacturers and industrial electrical engineers requiring a dedicated control power supply from higher-voltage industrial distribution systems.
Featuring 0/500/550/600/690 V primary terminals, the WV100P8S8 supports multiple nominal primary supply voltages through dedicated winding taps. Its two 0/110/120 V secondary windings can be connected in parallel to provide 110 V or 120 V AC, or connected in series to provide 220 V or 240 V AC. This flexible winding arrangement allows the same transformer model to accommodate different industrial control voltage requirements.
With a rated capacity of 100 VA, Class E insulation and 12% voltage regulation, the ETE WV100P8S8 provides a practical solution for low-power industrial control applications. Its compact dimensions of 85 × 70 × 93 mm and weight of 1.5 kg support straightforward integration into electrical control panels. The specified enclosure references are EPH 1 or EPN 1, allowing appropriate enclosure selection for the installation.
Industrial control transformers convert an available electrical supply voltage into a suitable secondary voltage for control circuits and connected equipment. The ETE WV100P8S8 is designed for applications using higher-voltage industrial supplies, with primary terminals for 500, 550, 600 and 690 V AC. Selecting the appropriate primary winding tap allows the transformer to provide its specified secondary voltage configuration from the corresponding nominal supply.
The transformer incorporates two 0/110/120 V secondary windings that can be configured according to the control system requirements. Correct parallel connection provides 110 V or 120 V AC, while correct series connection provides 220 V or 240 V AC. Parallel connections require matching secondary voltage taps and correct winding polarity, while series connections must follow the manufacturer's approved wiring arrangement. The transformer's total rated apparent power remains 100 VA in either configuration.
With 12% voltage regulation and Class E insulation, the WV100P8S8 offers a defined electrical performance specification for industrial control circuit design. The voltage regulation characteristic should be considered when selecting equipment sensitive to voltage variation, particularly where the load changes significantly. Its compact construction and EPH 1 or EPN 1 enclosure references make it suitable for integration into appropriately designed electrical panels with adequate ventilation, electrical protection and safe working clearances.

The ETE WV100P8S8 is a 100 VA single-phase wide-input-voltage control transformer designed to supply compatible industrial control circuits, electrical panels and automation equipment from nominal primary supplies of 500, 550, 600 or 690 V AC.
The transformer has a rated apparent power of 100 VA (0.1 kVA). The total connected secondary load must remain within this rating, whether the secondary windings are connected in series or parallel.
The transformer features 0/500/550/600/690 V primary terminals, providing dedicated connections for nominal 500, 550, 600 and 690 V AC supplies.
The WV100P8S8 has two 0/110/120 V secondary windings. These can be connected in parallel to provide 110 V or 120 V AC, or in series to provide 220 V or 240 V AC, using the correct winding connections.
Yes. The two secondary windings can be connected in parallel for 110 V or 120 V AC output. Matching voltage taps and correct winding polarity are essential to prevent circulating currents and possible transformer damage.
Yes. Connecting the two 120 V secondary windings correctly in series provides a nominal 240 V AC output. Similarly, the two 110 V secondary windings can be connected in series to provide a nominal 220 V AC output.
Yes. The transformer includes a dedicated 690 V primary terminal, allowing connection to a compatible nominal 690 V AC supply when installed and protected according to the manufacturer's requirements.
The transformer has a specified 12% voltage regulation. This should be considered when selecting connected control equipment, especially where voltage variation between no-load and loaded operation may affect performance.
The ETE WV100P8S8 uses Class E insulation, providing a defined thermal insulation classification for operation within the transformer's specified electrical and environmental limits.
The transformer measures 85 × 70 × 93 mm (L × W × H) and weighs 1.5 kg, making it suitable for compact industrial electrical panel installations.
The specified enclosure references are EPH 1 or EPN 1. Enclosure selection should also consider installation conditions, ventilation, wiring clearances and the required degree of protection.
The transformer is intended for integration into appropriately designed industrial control panels, machinery electrical cabinets and automation systems.
