Installation notes

Connect the LED load to the screw terminals under the removable cover, observing polarity (LED+ and LED–).
Incorrect wiring can damage the power supply and connected LEDs and is not covered by warranty.
Allow adequate air flow around the driver for free air cooling.
Indoor use only (IP20). Do not install in damp or wet locations.
Always follow local electrical regulations and, where required, have installation carried out by a licensed electrician.

Typical applications

Use the 40 W 12 V indoor transformer for:

Indoor LED strip lighting in retail, offices and commercial fitouts
Slim lightboxes and menu boards
Indoor LED signage and logo boxes
Under shelf, cabinet and display lighting in shops, bars and cafés
Small moving sign and display systems that require a 12 V constant voltage LED driver

For print and signage businesses, this is a go-to driver for powering 12 V LED modules behind acrylic panels, Eurotech lightboxes and small illuminated signs.
