The LUD-040SxxxDSF series is a 40W, constant-power, programmable IP20 LED driver that operates from 90-
305 Vac input with excellent power factor. Created for dimmable panel lights and linear lights, it provides good
dimming accuracy down to 5% output, plus a dim-to-off mode with low standby power. The high efficiency of
these drivers and slim metal case enables them to run cooler, significantly improving reliability and extending
product life. To ensure trouble-free operation, protection is provided against open lamp protection, short circuit,
and over temperature of both the driver and the external LED array.
