Industrial control transformers convert a higher-voltage AC supply into a lower-voltage AC output suitable for electrical control circuits and automation equipment. The ETE MV1000P2S3 is designed for compatible 380/420 V AC primary supplies, providing galvanic isolation between its primary and secondary windings while delivering dependable low-voltage power.
The transformer incorporates two separate 12 V secondary windings that can be configured to suit different applications. With the windings correctly connected in parallel, the transformer supplies 12 V AC with a theoretical full-load output current of approximately 83.3 A. When correctly connected in series, it provides 24 V AC with a theoretical full-load output current of approximately 41.7 A. These figures are calculated from the 1000 VA rating and nominal secondary voltages; actual operating limits must follow the manufacturer's specifications.
The primary winding includes a 20 V adjustment tap to accommodate the specified primary terminal arrangement. The correct connection of this adjustment tap must be confirmed with ETE before energising the transformer. Correct winding polarity, protective devices, cable sizing and terminal connections are essential for safe operation, particularly when connecting the secondary windings in series or parallel.
