Enhance your LED lighting with our versatile 24V LED Dimmer Module, featuring smooth, flicker-free dimming and a robust 120W load capacity for seamless control in various settings. It allows efficient operation of high-brightness LED strings from voltage sources ranging up to 400 VDC. The HV9925 includes an internal high-voltage switching MOSFET controlled with a fixed. Most designers use one of two methods: analog dimming or digital pulse-width modulation (PWM) dimming. There are two ways to implement digital PWM dimming: an enabling on/off approach or a shunt-field effect transistor (FET) approach. The high level of integration reduces the. National's industry-leading TRIAC dimmable offl ine LED driver solution is perfect for any application where an LED driver must interface to a standard TRIAC wall dimmer.
