Adjustable Constant Voltage LED Drivers
uPowerTek Adjustable Constant Voltage LED Drivers are designed to simplify inventory management and increase project flexibility. With a single driver supporting selectable 24V, 36V, and 48V output voltages, users can reduce SKU quantity while adapting to different lighting system requirements.
The output voltage can be adjusted directly through the built-in push button, allowing quick on-site configuration and fine tuning for applications such as long LED strip installations where voltage drop compensation is required. Combined with industrial-grade reliability, comprehensive protection functions, and multiple dimming options, the series provides a practical solution for modern architectural, commercial, and outdoor lighting projects.

Why Adjustable Constant Voltage
One SKU for 24V / 36V / 48V
Reduce inventory complexity by covering multiple voltage requirements with a single driver. Fewer SKUs mean lower stock costs, simplified purchasing, and faster project fulfillment.


External Voltage Adjustment
Easily switch between 24V, 36V, and 48V using the external adjustment button. No additional tools or driver replacement required, helping installers save time during commissioning.
Voltage Drop Compensation
Fine-tune the output voltage on-site to compensate for voltage drops in long LED strip installations. This helps maintain consistent brightness and lighting performance across the entire system.


Multiple Dimming Options
Available with 0-10V, DALI-2, and DMX control interfaces, allowing seamless integration into different lighting control systems and providing greater flexibility for project design.
