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

Product Description

The Elca TM150 is a single-phase control transformer rated at 500 VA, designed to step down standard line voltages (220 V or 380 V AC) to a low, safe 24 V AC output. This transformer is intended specifically for powering control circuits, contactors, push buttons, indicator lights, and other low-voltage components within industrial control panels.

Manufactured with high-quality materials, the TM150 provides stable voltage output, electrical isolation, and thermal protection, ensuring long-lasting, safe performance in demanding environments.
