TCI Electronic Transformer WU 105 12V ac 105W dim

The TCI Electronic Transformer WU 105 is a dimmable 12V AC 105W transformer designed for professional installations with LED or halogen low-voltage lamps. Built in polycarbonate with an IP20 protection rating and Class II insulation, it ensures safety against direct and indirect contact without the need for earthing.

Thanks to IGBT-TRIAC regulation combining Trailing Edge and Leading Edge technology, this TCI transformer integrates seamlessly with the most common dimming systems, offering maximum flexibility in residential and commercial installations requiring precise light intensity control.

Main technical specifications

The transformer accepts an input voltage of 220-240V and delivers a stable 12V AC output, with an adjustable power range from 20W to 105W. Its compact dimensions — 122 x 38 x 28 mm — allow installation in tight spaces. Input and output terminal blocks are located on the same side with a 2.5 mm² cross-section, and cable clamps on both primary and secondary circuits accommodate cable diameters from 3 mm to 8 mm. The unit is secured via slotted screw fixings.

Safety and protections

The TCI WU 105 features a comprehensive protection system: it safeguards against overheating and short circuits, against mains voltage spikes and against overloads, ensuring reliable long-term performance under any operating condition.

Applications

Ideal for design lighting installations, residential environments, retail spaces and contract projects requiring compatibility with 12V LED and halogen sources and smooth, precise dimming control.
