※ Built-in 3 in 1 dimming function, IP67 rated. Output constant current level can be adjusted through output cable by connecting a resistance or
0 ~ 10Vdc or 10V PWM signal between DIM+ and DIM-.
※ Please DO NOT connect "DIM-" to "-V".

※ Note : 1. Min. dimming level is about 6%
2. The output current is not defined when 0%<Iout<6%
3. The output current could drop down to 0% when dimming input
is about 0KΩor 0Vdc, or 10V PWM signal with 0% duty cycle
