Flexible 380–480 V Input with 24 V or 48 V AC Output
The ETE WV200P7S7 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 0/24 V secondary windings. When connected in parallel with matching voltage and correct winding polarity, the windings provide a 24 V AC output. When connected in series with the correct additive polarity, they provide a 48 V AC output. This arrangement allows the transformer to support different control circuit voltages without requiring separate transformer models.
Based on its 200 VA rating, the theoretical full-load secondary current is approximately 8.33 A at 24 V AC in the parallel configuration or 4.17 A at 48 V AC in the series configuration. These values assume the full rated apparent power is available in the selected connection arrangement. Actual permissible winding currents and loading requirements must follow ETE's specifications.
The specified 10% voltage regulation means secondary voltage variation between operating load conditions should be considered when selecting connected equipment. Sensitive devices requiring tightly regulated power may need additional voltage regulation. Correct primary tap selection, secondary winding polarity, suitable circuit protection and appropriate conductor sizing are essential for safe installation.
