Application of introduction

1. MCS interface(MCS+/MCS-)

  • MCS+ interface voltage 15V
  • Max current setting(each step is 1 mA), default driving current defined as 350mA.
  • Log or linear dimming curve, the default setting is log dimming.
  • NTC thermal management protects LED lamps, when the temperature of the LED lamp is over-temperature protection point, the current will be reduced by 50% every 5 minutes. The default setting is 85℃.
NTC compatibility


NTC Manufacturer NTC Model NO.
  • Control the status of Auxiliary power when dim level =0. Enable standby mode: when dim level =0, the Auxiliary power will be closed. Disable standby mode: when dim level =0, the auxiliary power still can work. The default setting is enabled.
  • update Online, use the smart key to connect the PC and the driver to update the firmware.

2. Dimming performance

  • When changed to any dimming level, flicker wouldn’t occur, dimming would be achieved smoothly.
  • In the range of 200~1500mA, the current operating in continuous mode; In the range of 0~200mA, the current operating in PWM dimming mode, and the PWM frequency 3.6KHZ.
