4-Channel Series
The product, providing high stable and efficient power, adopts DSP control and high-frequency switching constant current driver; moreover, it is up to the adjustment function of 4096-level current digital to be suitable for different watts of LED light system. It can effectively extend the life of LED light by accurate constant current.
The light and small design can save more spaces. Also, the isolated communication design for USB 2.0 enhances the reliability and safety of system communication and effectively simplifies the system.
  • Product Features:
  • USB interface for electrical isolation; ultra-high speed strobe optical receiver
  • Digital knob to adjust output current with 7-segment display indicator; channels can be adjusted and storage individually
  • High-current driving capacity:maximum 3000mA output current per channel
  • Build-in power supply
  • LED open-loop detection and short-circuit protection:automatically stop output current when no-load or short-circuit
  • Alarm and protection:abnormal input power、system over-current、system overheats
  • Precision current adjustment resolution:digital knob provides 256 adjusting current levels, USB interface provides 4096 adjusting current levels
  • High-efficiency and high-power factor power circuit
  • LED strobe output width can be adjusted from 1us~64s of exposure width
  • External pulse switch control:provides periodic external trigger switch signal to synchronize LED strobe; the minimum width of LED output reaches to 10us; the maximum frequency of strobe output reaches to 100KHz.
  • Each channel provides 256 sets of programmable and non-volatile LUT units to help users quickly correspond different currents and various brightness & characteristic of LED Lights
