LED transformer power supply 40–45 W – 12 V DC / 4 A | desktop power supply 100–240 V

Sompex LED Desktop Power Supply 12 V DC 4 A 40–45 W at a glance

The Sompex LED desktop power supply with 12 V DC and 4 A is a high-performance power source for compatible constant-voltage LED lighting. With an output of 40–45 W, the power supply is particularly suitable for LED strips, LED ribbons, under-cabinet lights, and other 12 V LED systems with medium power requirements.

The universal input of 100–240 V AC at 50–60 Hz allows for flexible use. Thanks to its compact desktop design, IEC power connection, and the approx. 100 cm long DC output cable, the power supply is suitable both as a replacement for an existing LED power unit and for suitable new lighting installations.

12 V DC constant voltage for LED lighting

The 12 V LED power supply with 4 A delivers a constant DC voltage of 12 V. It is therefore suitable for LED components specifically designed for a 12 V constant-voltage power supply.

40–45 W power for versatile applications

With a power range of 40–45 W, the desktop power supply offers sufficient power for numerous LED applications. These include, for example, LED strips, LED bars, under-cabinet lights, and other compatible 12 V DC consumers.

Up to 4 A output current

The maximum output current is 4 A. This makes the power supply suitable for lighting systems with multiple connected LED components, provided the permissible total power is maintained.

IEC connection and 100 cm DC output cable

On the primary side, the power supply features an IEC power connection. On the secondary side, there is an approx. 100 cm long DC output cable, which enables flexible connection to compatible LED controllers, distributors, or lighting systems.
