The HK9981 LED controller is a compact electronic module designed for controlling LEDs and LED modules using a single output channel. It is suitable for advertising signs, decorative lighting, and various lighting effect applications.
The controller is based on a PIC microcontroller and features 7 pre-programmed lighting effects, plus a demo mode. The demo program automatically cycles through all 7 programs, repeating each one 5 times.
Program selection is performed via a push button. 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.
