Flexible 380–480 V Input with 110/120 V or 220/240 V AC Output
The ETE WV1000P7S8 is designed for industrial control installations where the available primary supply voltage may differ between machines, facilities or electrical systems. Its selectable primary terminals support 380, 400, 420, 440, 460 and 480 V AC, allowing the transformer to be configured for several compatible industrial supply voltages.
The transformer incorporates two secondary windings, each with 0/110/120 V terminals. Connecting matching secondary winding taps in parallel with the correct polarity provides 110 V or 120 V AC. Connecting the windings in series with the correct additive polarity provides 220 V or 240 V AC. All winding connections must follow ETE's instructions to ensure correct voltage selection and safe operation.
Based on its 1000 VA rating, the theoretical full-load secondary current is approximately 9.09 A at 110 V AC, 8.33 A at 120 V AC, 4.55 A at 220 V AC or 4.17 A at 240 V AC. These calculated values assume the full rated apparent power is available in the selected configuration. Actual permissible winding currents and loading requirements must follow ETE's specifications.
The specified 4% voltage regulation means secondary voltage variation between operating load conditions should be considered when selecting connected equipment. Correct primary tap selection, secondary winding polarity, suitable circuit protection, conductor sizing and appropriate installation clearances are essential for safe operation. Sensitive electronic equipment requiring a tightly regulated supply may need additional voltage regulation.
