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

Product Description

The Elca TM250 is a high-power, single-phase dry-type control transformer rated at 5000 VA (5 kVA). Designed specifically for industrial environments, this transformer provides electrical isolation without changing the voltage level — delivering the same output voltage as the input (220 V or 380 V AC). This makes it ideal for applications where voltage matching is required with full galvanic separation to protect sensitive control equipment.

Whether used in automation systems, control panels, or heavy machinery, the TM250 ensures safety, noise suppression, and voltage stability in complex electrical systems.
