Meanwell DRA-40-24 DIN Rail Power Supply 24V 1.7A 41W Dimmable 0-10V PWM

The Meanwell DRA-40-24 is a fanless AC-DC DIN rail power supply with a 24VDC 1.7A (41W) output and built-in dimming control. It accepts a universal input of 90-264V AC and supports output dimming via 0-10V DC signal, PWM signal, or resistance control, making it suitable for both industrial 24V supply applications and LED lighting systems requiring variable output.
