The ETE WV2000P7S8 is designed for electrical installations where several nominal industrial supply voltages may be encountered. Its primary winding includes terminals marked 0/380/400/420/440/460/480 V, allowing the appropriate voltage connection to be selected for the available supply.
This arrangement is particularly useful for OEM machinery manufacturers, industrial panel builders and equipment suppliers working with installations that use different supply voltages. Rather than requiring a separate transformer model for every nominal voltage, the WV2000P7S8 provides six primary voltage options within one product.
The primary terminals are discrete winding taps, not an automatic voltage-ranging input. The correct connection must be selected before energising the transformer, following ETE's wiring instructions and applicable electrical safety requirements.
With a 2 kVA rating, the WV2000P7S8 can accommodate substantial compatible control loads, subject to appropriate load calculations, circuit protection and installation arrangements.
Selectable 110/120 V AC or 220/240 V AC Secondary Outputs
A principal advantage of the WV2000P7S8 is its dual-secondary winding configuration. The transformer incorporates two separate windings, each with terminals marked 0/110/120 V, allowing the output voltage to be configured for different industrial control applications.
- 110 V AC parallel output: Both secondary windings are connected in parallel using their corresponding 110 V taps and the correct winding polarity.
- 120 V AC parallel output: Both secondary windings are connected in parallel using their corresponding 120 V taps and the correct winding polarity.
- 220 V AC series output: The two 110 V winding sections are connected in series with the correct polarity to provide a nominal combined output of 220 V AC.
- 240 V AC series output: The two 120 V winding sections are connected in series with the correct polarity to provide a nominal combined output of 240 V AC.
The 2000 VA rating applies to the complete transformer and must not be interpreted as 2000 VA available independently from each secondary winding. Parallel connections require correctly matched voltage taps and winding polarity, while series connections must be arranged for the intended combined voltage.
All secondary connections should follow ETE's wiring instructions, including suitable winding phasing, load assessment and protective devices. Incorrect series or parallel connections may damage the transformer or connected equipment.
Dependable Performance with 3% Voltage Regulation
The ETE WV2000P7S8 has a specified 3% voltage regulation, indicating the change in secondary voltage between the manufacturer's defined loading conditions. This characteristic supports dependable voltage performance for appropriately selected industrial control equipment.
Combined with its Class E insulation system, 2000 VA rated capacity and selectable voltage connections, the transformer provides a practical option for industrial installations where control power requirements and available primary supply voltages vary.
