The Octoglass company has developed and patented controllers that allow you to control electrochromic systems in particular electrochromic tinting in a car. Our model range includes such controllers as KDS-2, KDS-2 Mini and KDS-2 nano. Our controllers provide operating voltages up to 4 volts inclusive with a peak current of up to 3 amperes which makes them completely safe. And at the end of 2021 we released a new firmware for the controllers which provides the ability to work on the standard CAN bus.
