PWM-40 series is a 40W LED AC/DC LED driver featuring the constant voltage mode with PWM style output, which is able to maintain the color temperature and the brightness homogeneity when driving all kinds of LED strips.PWM-40 operates from 90~305VAC and offers models with different rated voltage ranging between 12V and 48V.Thanks to the high efficiency up to 90%, with the fanless desian, the entire series is able to operate for -40℃~+85℃ case temperature under free air convection. The entire series is rated with lP67 ingress protection level and is suitable to work for dry,dampor wet locations.PWM-40 is equipped with dimming function that varies the duty cycle of the output, providing great flexibility for LED strips applications.
