Evaluation report: 0-10V/potentiometer LED color temperature adjustment solution GML003 [Copy link]

LED color temperature adjustment is a basic function in intelligent lighting, and the 0-10V interface is a low-cost universal interface in the field of LED dimming. Therefore, Keyi Electronics has launched a color temperature adjustment module based on the 0-10V interface, which can directly expand ordinary constant current and constant voltage LED driver power supplies into 0-10V color temperature adjustment power supplies.

Common LED driver power supplies are divided into constant voltage output and constant current output. Constant voltage power supplies are suitable for driving LED light strips with built-in current limiting resistors, while constant current power supplies are suitable for driving LED light strings without current limiting resistors. The 0-10V color temperature adjustment module GML003 we launched can be compatible with both.

Description: The GML003 module uses a pair of outputs of the LED driver as power, and connects to a 0-10V signal or a 100K ohm potentiometer through the VDIM port to linearly adjust the current through the cold and warm light LEDs, thereby achieving uniform color temperature adjustment. The working power supply voltage of this module is 24V~80V, the color temperature adjustment signal is 0-10V or a 100K ohm potentiometer, and the maximum output drive current can reach 10A.
