This little unit packs a big punch with a massive 30A capability. From 100% full brightness down to 20% without flickering. It's to be placed between the 12v/24v supply of the PSU and the LED. Simply turn the dial to adjust the brightness to your personal needs.
Due to the dimmer having open screw terminals, it would need to be placed in a waterproof enclosure if the dimmer needs to be situated outside. It doesn't need airflow.
Operating Voltage : 12v or 24v Temperature Range: -20 to 60C Dimensions: 83 x 64 x 24mm + fitting plates Output Current: Max 30A
**To figure out how many amps your LED will use, divide the total number of Watts by the voltage. ie: 200 x SG3 LED modules @ 0.3w each = 60w total - 60w divided by 12v = 5amps
