Elca TM175 | Control transformer 750 V.A “IN 220/380 – OUT 12/24/48/70/110”
Product Description
The ELCA TM175 is a versatile and rugged single-phase control transformer, rated at 750 VA, tailored for industrial automation and control panel applications. It accepts dual primary voltages—220 V or 380 V AC—and provides a wide range of selectable secondary voltages: 12 V, 24 V, 48 V, 70 V, and 110 V AC. This multi-output capability allows a single transformer to power various control devices and circuits with differing voltage requirements.
Constructed for durability and reliability, the TM175 ensures electrical isolation between primary and secondary windings, protecting sensitive control components from power-line disturbances and enhancing operational safety. Its compact, dry-type design supports efficient mounting within control panels and electrical enclosures.
