Why Choose the ETE WV300P8S8 Wide-Input-Voltage Control Transformer?
The ETE WV300P8S8 is a versatile 300 VA single-phase wide-input-voltage control transformer designed for AC voltage transformation and electrical isolation in 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 choice for control panel builders, OEM machine manufacturers and industrial maintenance engineers.
The WV300P8S8 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 for 110 V or 120 V AC output, or in series for 220 V or 240 V AC output. This flexible arrangement allows one transformer model to accommodate several common industrial control voltage requirements.
With a rated capacity of 300 VA, Class E insulation and 8% voltage regulation, the ETE WV300P8S8 offers a balance of electrical capacity, voltage flexibility and compact construction. Measuring 120 × 100 × 120 mm and weighing 4.7 kg, it is suitable for installation in appropriately designed industrial electrical equipment, with associated EPH 3 or EPN 2 enclosure references.

Flexible 110 V, 120 V, 220 V and 240 V AC Control Power from Higher-Voltage Industrial Supplies
The ETE WV300P8S8 transforms a selected industrial AC input voltage into a secondary supply suitable for compatible control equipment. Its four nominal primary voltage connections make it useful in installations operating at 500 V, 550 V, 600 V or 690 V AC. The correct primary terminal must be selected to match the available supply, and all connections must follow the manufacturer's instructions.
On the secondary side, the transformer incorporates two windings, each marked 0/110/120 V. When correctly connected in parallel, corresponding winding taps provide a 110 V or 120 V AC supply. When connected in an additive series arrangement, 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.
The transformer's 300 VA capacity is the total rated apparent power, not a separate 300 VA allowance for each secondary winding. It can supply one or more compatible control loads, provided their combined continuous and starting requirements remain within the permitted transformer and winding ratings. Its specified 8% voltage regulation should be considered when selecting connected equipment, particularly where voltage tolerance is important.
With Class E insulation, a compact footprint and a 4.7 kg weight, the WV300P8S8 is suited to appropriately supported industrial control panel installations. The associated EPH 3 or EPN 2 enclosure references identify manufacturer enclosure options. Because the primary connections include voltages up to 690 V AC, installation design must provide appropriate insulation clearances, circuit protection, isolation arrangements, earthing and safe access for maintenance.
