OUTPUT CURRENT ADJUSTMENT OPERATION
※ Built-in 3 in 1 current adjustment function . Output constant current level can be adjusted by applying 1 ~ 10Vdc, 10V PWM
signal or resistance between DIM+ and DIM-.
※ Please DO NOT connect "DIM-" to "-V".
※ Reference resistance value for output current adjustment (Typical)
