TCI EF 50 – Electronic 12V Halogen Transformer 20–50 Watts

TCI EF 50 electronic halogen transformer 20–50 W at a glance

The TCI EF 50 electronic halogen transformer is designed for classic 12 V low-voltage halogen lighting. It converts an input voltage of 230 V AC into 12 V low voltage and is particularly suitable for recessed halogen spotlights, spot lights, furniture lighting, as well as ceiling and display case lights.

With a power range of 20 to 50 W and an especially flat design of only 20 mm in height, the transformer can also be used in confined installation spaces. VDE approval, SELV output, and integrated protective functions ensure reliable operation.

20–50 W for low-voltage halogen lighting

The 12 V halogen transformer with 50 W operates within a power range of 20 to 50 W, making it suitable for appropriately sized halogen lamps and low-voltage spotlights.

12 V output for halogen spotlights

On the output side, the TCI EF 50 provides a voltage of 12 V. This makes the transformer suitable for compatible 12 V halogen bulbs and corresponding low-voltage lighting systems.

Flat design for tight installation spaces

With dimensions of 145 × 55 × 20 mm, the transformer features a very flat design. This makes it particularly easy to integrate into furniture, ceiling areas, and compact light fixtures.

SELV and integrated protective functions

The electronic transformer features a SELV output as well as protection against overload, short circuits, and thermal overload. Additionally, the device is VDE and CE approved.
