Reliable 24 V and 48 V AC Control Power for Industrial Automation
Industrial control transformers convert an available AC supply voltage into a suitable secondary voltage for electrical control circuits and connected equipment. The ETE WV1000P7S7 provides a flexible solution for installations using nominal primary voltages of 380, 400, 420, 440, 460 or 480 V AC. Selecting the appropriate primary terminal allows the transformer to accommodate the specified industrial supply without requiring a different transformer model for each listed voltage.
The transformer's two 0/24 V secondary windings allow different output arrangements. When correctly connected in parallel, they provide a nominal 24 V AC output, with the load shared between the windings. Alternatively, a correct series connection provides a nominal 48 V AC output. The transformer's total rated capacity remains 1000 VA in either configuration. Parallel connections must observe correct winding polarity, while series connections must follow the manufacturer's approved terminal arrangement.
The specified 4% voltage regulation is an important consideration when selecting control devices that require a relatively consistent AC supply. At its rated capacity, the transformer offers calculated nominal output currents of approximately 41.67 A at 24 V or 20.83 A at 48 V, subject to the manufacturer's winding ratings and installation requirements. Correct primary tap selection, secondary wiring, protective devices, ventilation and mechanical mounting are essential for dependable operation.
