Interface
Ideally the module should have only two pins and behave as a constant current sink, but for
practical reasons, and in order to gain a higher degree of flexibility, its connector has the
following pinout.

Pin number
D_Dimm is a digital (TTL) input for the module. A high level shuts off the circuit. A low
level enables the nominal load current and a square wave with variable duty cycle can
be used as a dimming control
C_Set is an analog input (0...12 V). A voltage applied to this pin is used to set the load
current to the required value
Gnd pins 3 and 4 are the ground return for the controller’s power supply (Vcc). D_Dimm
and C_set are referred to this ground
Vcc is the connection to the controller’s power supply input
Vin_Gnd is the main power supply return, internally connected to the Gnd pins
Vin is the main power supply input (48 V)
LEDs_A is the connection to the anode of the diode string
LEDs_K is the connection to the cathode of the diode string
