Flexible Low-Voltage Power for Industrial Control Systems

Industrial control transformers such as the ETE MV250P2S3 convert an incoming AC supply into a lower voltage suitable for control circuits and automation equipment. The MV series is designed to offer flexible voltage configurations, helping electrical engineers and machine builders select suitable transformer connections for different industrial control requirements.

The MV250P2S3 incorporates two 12 V secondary windings, allowing the transformer to supply either 12 V AC through a parallel connection or 24 V AC through a series connection. Parallel connections require correct winding polarity and compatible winding characteristics, while series connections must be arranged for voltage addition. The combined load must remain within the transformer's 250 VA rating.

The primary winding features terminals marked 20/0/380/420 V, including a 20 V adjustment tap. This adjustment facility supports the manufacturer's specified primary connection arrangements, but the exact terminal selection and adjustment method must be confirmed with ETE before energising the transformer. Its Class E insulation and specified 8% voltage regulation further define its electrical operating characteristics.

Typical Applications

  • Industrial electrical control panels requiring 12 V or 24 V AC supplies.
  • Machine control circuits and industrial automation systems.
  • Compatible AC relays, contactors and switching equipment.
  • Manufacturing and production machinery.
  • Packaging and material handling equipment.
  • Low-voltage AC control and signalling circuits.
  • OEM machinery and electrical panel building.
  • Industrial maintenance and replacement transformer installations.
