Electronic transformer ETA 105R – 120V USA → 11.5V AC, 35–105 W, dimmable

Sompex ETA 105R Halogen Transformer 120 V 35–105 W at a glance

The Sompex ETA 105R electronic transformer is a compact, round converter transformer for low-voltage lighting on 120 V power grids. It converts 120 V AC to 11.5 V AC, making it particularly suitable for halogen lamps and compatible LED light sources that are explicitly designed for operation with AC voltage.

With a power range of 35–105 W and its dimmable design, the electronic halogen transformer is especially suitable for export luminaires, US lighting projects, and for replacing a technically compatible transformer. The round design allows for space-saving integration into suitable luminaire housings, canopies, or false ceilings.

120 V AC for US power grids

The electronic transformer for 120 V is specifically designed for corresponding US power grids and operates at a mains frequency of 50–60 Hz. The input current is 0.80 A.

11.5 V AC for low-voltage lighting

On the output side, the ETA 105R provides a voltage of 11.5 V AC. This makes it suitable for compatible low-voltage halogen lamps and AC LED light sources whose electrical requirements match the transformer.

35–105 W power range

The transformer operates within a power range of 35 to 105 W. The minimum load of 35 W must be maintained, while the total connected load must not exceed 105 W.

Dimmable with a suitable dimmer

The dimmable halogen transformer for 12 V low-voltage lighting can be operated in conjunction with a suitable dimmer. The dimmer used must be explicitly suitable for electronic transformers.

Compact round design

With a diameter of 95 mm and a height of 35 mm, the black transformer can be integrated into suitable luminaire designs in a space-saving manner. The housing is made of plastic and is designed for indoor use.

Typical areas of application

• 12 V low-voltage halogen lighting

Important note

The transformer is intended exclusively for an input voltage of 120 V AC. The minimum load of 35 W must be maintained and the maximum total power of 105 W must not be exceeded.

The output delivers 11.5 V AC alternating current and is therefore not suitable for consumers that explicitly require direct current. For dimming, a dimmer must be used that is suitable for electronic transformers. Due to its IP20 protection class, the transformer is intended exclusively for indoor use.
