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

Product Overview

The Elca TM150 is a single-phase, dry-type isolation/control transformer with a rated capacity of 500 VA. It is designed for industrial applications requiring electrical isolation, voltage matching, or noise reduction between input and output lines operating at 220 V or 380 V AC.

With the same voltage on both sides (IN = OUT), this transformer doesn’t change the voltage level — instead, it serves to electrically isolate the circuits and enhance the safety and reliability of control systems or auxiliary power supplies.

Key Features

Voltage Matching with Isolation
Transfers 220 V or 380 V AC from input to output without changing voltage, but with full galvanic isolation for safety.

Compact Power Rating
The 500 VA rating is ideal for control circuits, auxiliary equipment, and small machines.

Low Noise & EMI Reduction
Provides excellent suppression of electrical noise and disturbances between the supply and the load.

Long-Term Reliability
Built using low-loss cores and thermally stable insulation materials for durable and efficient operation.

Flexible Installation
Designed to fit easily into control panels or enclosures, with user-friendly wiring terminals.

Typical Applications

Isolation of control circuits from power sources to prevent ground loops or interference

Safety barrier between line voltage and control panels

Voltage stabilization and filtering in electrical panels

Supplying auxiliary power to motor starters, contactors, or timers

Preventing electrical noise from transferring between systems
