Elca TM150 | Control transformer 500 V.A “IN 220/380 – OUT12/24”

Product Description

The Elca TM150 is a single-phase, dry-type control transformer rated at 500 VA, specifically designed for stepping down industrial voltages (220 V or 380 V AC) to safe low-voltage levels of 12 V or 24 V AC. This transformer is used in control circuits where safety, voltage stability, and isolation from the main power supply are critical.

It features selectable dual output voltages (12 V and 24 V AC), allowing greater flexibility for powering different control components such as indicator lights, push buttons, relays, timers, and low-voltage automation systems.
