PowerMaster 42W 1000mA Dimmable Constant Current LED Driver – IP20

Description

The PowerMaster S17441 is a 42W constant current LED driver delivering 1000mA output to LED luminaires. The driver accepts 220-240V mains input and regulates a constant 1000mA current across an output voltage range of 20-42V DC, allowing it to power LED arrays totalling between 20W and 42W depending on their forward voltage drop.

Designed for indoor residential, commercial and retail lighting installations where dimming control is needed, the driver supports both DALI (digital addressable lighting interface) and Triac phase-control dimming protocols. The dimming range runs from 1% to 100%, giving fine control at the low end without flicker or dropout. The isolated circuit topology separates mains input from DC output, making the driver suitable for both Class I (earthed) and Class II (double-insulated) luminaires.

The driver measures approximately 140mm x 42mm x 21mm and weighs 130g, fitting inside most recessed downlig
