MEAN WELL A301-100-F3 DC/DC Constant Current LED Driver 100W 3.5A 3-30V

The MEAN WELL A301-100-F3 is a DC/DC constant current LED driver delivering up to 100 W of power with a high efficiency of 96%. It operates from a 9-36 V DC input and provides a constant current of 3500 mA across an output voltage range of 3-30 V DC. This driver supports 3-in-1 dimming (0-10 VDC, PWM, resistance) and features comprehensive protections including short circuit, over voltage, over temperature, and input under voltage. Its wide operating temperature range from -40°C to +70°C and free air convection cooling make it suitable for demanding LED lighting applications.

Advantages
