Meanwell PWM-120 LED-Powersupply for perfect dimming of LED-Stripes
PWM-120 series is a 120W 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 120 operates from 90~305VAC and offers models with different rated voltage ranging between 12V and 48V. Thanks to the high efficiency up to 90.5%, with the fanless design, the entire series is able to operate for -40 ? ~ +90 ? case temperature under free air convection. The entire series is rated with IP67 ingress protection level and is suitable to work for dry, damp or wet locations. PWM120 is equipped with dimming function that varies the duty cycle of the output, providing great flexibility for LED strips applications.

PowerPower depending of individuel operation mode and configuration:120WMaximum power, depending of configuration and operation mode. For details please check the datasheet.
Dimmable/ControlAvailability to control illumination:1..10VControl input for external voltage from 1-10V or passiv via potentiometer or specific 1-10V device., DALIDALI - specific lightinginterface. Needs further components like DALI-Controller. Each drivers has its own adress and via BUS-control it provides continously opportunity to dim and switch the light., PWMDimmable via PWM input
