Flexible 380–480 V Input with 24 V or 48 V AC Output
The ETE WV3000P7S7 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 0/24 V terminals. Connecting the two matching secondary windings in parallel with the correct polarity provides 24 V AC. Connecting the windings in series with the correct additive polarity provides 48 V AC. All winding connections must follow ETE's instructions to ensure correct voltage selection and safe operation.
Based on its 3000 VA rating, the theoretical full-load secondary current is approximately 125 A at 24 V AC or 62.5 A at 48 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 3% voltage regulation means secondary voltage variation between operating load conditions should be considered when selecting connected equipment. The potentially high secondary currents require particular attention to conductor sizing, terminal ratings, circuit protection and distribution arrangements. Correct primary tap selection, secondary winding polarity and appropriate installation clearances are essential for safe operation. Due to its 28 kg weight, the transformer also requires suitable mechanical support and safe handling during installation.
