Elca TM250 | Control transformer 5000 V.A “IN 220/380 – OUT 110/220”

Product Description

The Elca TM250 is a heavy-duty, single-phase dry-type control transformer rated at 5000 VA (5 kVA). It is engineered to provide electrically isolated, stable AC voltage for control systems in industrial environments. This model supports dual primary input voltages (220 V or 380 V AC) and provides dual secondary output voltages (110 V or 220 V AC), making it suitable for a wide range of control and auxiliary applications that require reliable voltage conversion and isolation.

The transformer is built for continuous-duty operation and is ideal for large control panels, automated machinery, and systems requiring safe voltage separation between the power source and control circuitry.
