Elca TM175 | Control transformer 750 V.A “IN 220/380 – OUT 12/24”

Product Description

The ELCA TM175 is a robust single-phase control transformer, delivering a power capacity of 750 VA. It accepts two common industrial primary voltages—220 V or 380 V AC—and provides dual secondary voltages of 12 V and 24 V AC, typically accessible via separate taps or selectable terminals. This flexibility enables a single transformer to serve control circuits with different voltage requirements, reducing space and simplifying panel design. Engineered for reliability, it ensures effective electrical isolation and consistent performance in demanding environments, while remaining compact enough for seamless integration into control panels and electrical enclosures.
