3 Phase to 240VAC Alternative: The TX-415 Range of AC Transformers

In installations where only three-phase power is available, supplying standard 240VAC equipment can be challenging—particularly where a neutral conductor is not readily accessible or practical to install. This often leads to additional work, including running a neutral, modifying distribution boards, and adding protection and filtering components.

A practical alternative is to use a 415VAC (line-to-line) primary transformer to generate a 240VAC secondary supply. This approach removes the need for a neutral line from the source supply by creating a separately derived voltage, simplifying wiring and reducing installation complexity.

The Power Source TX series offers a range of 415VAC input transformers with secondary outputs including 240VAC, 110VAC, and 24 VAC, with power ratings from 40VA up to 2500VA. These transformers provide galvanic isolation between primary and secondary, improving safety and reducing electrical noise transfer.

The TX series features Class B insulation (130 °C) and varnish-dipped windings for improved thermal performance and protection against moisture and environmental contaminants.
