Why Choose the ETE WV200P8S8 200 VA Wide-Input-Voltage Control Transformer?
The ETE WV200P8S8 is a 200 VA single-phase wide-input-voltage control transformer designed for industrial electrical installations requiring higher primary supply voltages and flexible secondary output configurations. Part of the ETE WV wide-input-voltage transformer series, it features 0/500/550/600/690 V primary terminals and two secondary winding groups marked 0/110/120 V + 0/110/120 V.
The WV200P8S8 supports 110 V AC or 120 V AC output with the secondary windings connected in parallel, or 220 V AC or 240 V AC output with the secondary windings connected in series. This versatility makes it suitable for industrial control panels, OEM machinery and automation equipment requiring different AC control voltages from compatible higher-voltage electrical supplies.
Its multi-tapped primary winding provides nominal input selections of 500 V, 550 V, 600 V and 690 V AC, allowing the appropriate terminal to be selected for the installation. The dual secondary winding arrangement offers additional flexibility, enabling electrical engineers to configure the output voltage to suit compatible control equipment without requiring a different transformer model for each supported secondary voltage.
With Class E insulation, 10% voltage regulation, dimensions of 96 × 87 × 103 mm and a weight of 2.8 kg, the ETE WV200P8S8 provides a compact and adaptable industrial control power solution. Its associated enclosure references are EPH 2 or EPN 1, supporting enclosure selection during electrical panel design.

Flexible Industrial Control Power for 500–690 V AC Supply Systems
The ETE WV200P8S8 provides a practical solution for industrial installations operating with higher primary supply voltages while requiring lower AC control voltages. Its primary terminals support nominal selections of 500 V, 550 V, 600 V and 690 V AC, allowing the transformer to be configured for compatible industrial electrical systems. The correct primary terminal must be selected to match the actual supply voltage and the manufacturer's connection instructions.
A key advantage is its two separate 0/110/120 V secondary windings. When connected correctly in parallel, the windings provide a nominal 110 V AC or 120 V AC output. Parallel operation allows the current contribution of both windings to be combined, subject to the transformer's overall 200 VA rating. Matching voltage taps and correct winding polarity are essential because incorrect parallel connections can produce damaging circulating currents.
When connected correctly in series, the secondary windings provide a nominal 220 V AC or 240 V AC output. This configuration combines the voltages of the two windings while retaining the transformer's overall apparent power rating. Correct winding polarity and terminal identification are important because incorrect series connections can result in voltage cancellation or an unsuitable output voltage.
At the rated 200 VA capacity, the calculated nominal secondary currents are approximately 1.82 A at 110 V, 1.67 A at 120 V, 0.91 A at 220 V and 0.83 A at 240 V. These figures are calculated from the transformer's apparent power rating and nominal output voltages rather than separately verified manufacturer current ratings. The 200 VA rating applies to the transformer as a whole and must not be interpreted as 200 VA independently available from each secondary winding.
The specified 10% voltage regulation is relevant when evaluating secondary voltage variation under changing load conditions. Actual output voltage depends on the selected primary tap, supply voltage, winding configuration and connected load. Equipment with narrow operating voltage tolerances should therefore be checked for compatibility, particularly where control relays, contactor coils or other inductive devices introduce changing loads.
With Class E insulation, compact dimensions and associated EPH 2 or EPN 1 enclosure references, the WV200P8S8 can be incorporated into appropriately engineered electrical control assemblies. Suitable primary and secondary circuit protection, conductor sizing, mounting, ventilation and electrical clearances must be provided. Because the primary connections include voltages up to 690 V AC, installation and maintenance must be carried out by suitably qualified personnel using equipment and protective arrangements appropriate to the supply voltage.
