Why Choose the ETE WV100P8S8 100 VA Wide-Input-Voltage Control Transformer?
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.

Reliable Wide-Input-Voltage Transformation for Industrial Control Systems
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.
