Elca TM125-S24 | Control transformer 250 V.A “IN 220/380 – OUT 110/220”

Product Description

The Elca TM125-S24 is a single-phase, dry-type control transformer rated at 250 VA, designed to supply isolated and stable voltage for industrial control circuits. With dual input options (220 V or 380 V AC) and dual output voltages (110 V or 220 V AC), this transformer offers versatile functionality for systems that require intermediate or standard voltages for control, signaling, or auxiliary equipment.

This model is especially useful in machines imported from regions using 110 V control systems, or in cases where voltage isolation and protection are needed without a significant power demand.
