"With high-precision dimming settings of 256/1000 gradations, you can achieve your desired results." The new 1-channel dedicated model LLBLM-A maximizes the performance of high-brightness LEDs. It offers high light stability through constant current control and flexibly accommodates a wide range of inspection and lighting applications with three types of interfaces: parallel, RS232C, and LAN. In addition to intuitive operation via the front panel, it supports high-precision dimming with 256/1000 gradations (256 gradations in parallel mode). The available emission colors are G (green) and B (blue). This new model balances stable light output with ease of use. For more details, please feel free to contact us.
