High power LED controller
LED driver embedded
One of the highest performance high-power LED driver in the world, is installed in the heart of the best LED follow spot light.
The next-generation constant-current LED driver, which optimized to drive high-power LED array was designed, programmed, tested and shipped. Using multiphase Buck converter topology, 6 channels are interleaving combined to produce a total output current up to 20A at 50V. With high power MOSFET, the board can handle 1kW power without a fan. The driving frequency is selectable between 1kHz – 5kHz to ensure no flickering for the camera. Using specialized microcontroller for power management, PWM signals with resolution down to 0.3 nanoseconds are generated to ensure smooth response of the LED array.
Features:
- Six independent LED driver with constant current features, the current of each channel is selectable via RDM.
- Each channel can drive each LED differently with different voltage and current.
- Multiple channels can be combined.
- Selectable 300W, 600W & 1kW achievable total output power.
- > 99% efficiency, fanless operation.
- Multiple dimming interfaces are supported: DMX, I2C, PUSH DIM, 0-10V, RESISTOR DIM.
- RDM compatible and configurable.
- 8-bit or 16-bit LED dimming with 0.3 nanosecond PWM resolution for smoother response.
- Automatic overcurrent protection.
- Low EMI with optimized board layout and effective noise suppression technique.
- Mostly automated pick and place SMD components
