The HK9982 LED controller is an electronic module designed to control LEDs and LED modules using two independent channels. It is suitable for advertising signs, decorative lighting, architectural lighting, and various lighting effect applications.
The controller is based on a PIC microcontroller and features 5 pre-programmed lighting effects, plus a demo mode. In demo mode, all 5 programs are executed automatically, with each program repeated 5 times.
Program selection is performed via a push button, while the effect speed is adjusted using a trimmer potentiometer. The controller includes non-volatile memory that stores the last selected program when power is removed.
The device operates from an 8 to 25V DC power supply. When using 12V LED modules, the supply voltage must be 12V. The maximum output current is up to 5A, depending on the connected LED load.
