LDD-1200H Description

Short technical summary and product information.

The Mean Well LDD-1200H is a constant current buck LED driver designed for high-efficiency LED lighting applications. It delivers a nominal output current of 1.2A over an output voltage range of 2 to 46V DC, with an input voltage range of 9 to 52V DC. The driver achieves up to 97% typical efficiency, minimizing power loss and heat generation.

 

This driver includes PWM dimming capability and remote on/off control, along with built-in over-temperature protection (OTP) and short-circuit protection (SCP) for reliable operation. The module is housed in a 24-DIP through-hole package with 9 leads, measuring 31.8 x 20.3 x 12.2 mm and weighing 15.19 g. It is rated IP67 for dust and water ingress protection, making it suitable for outdoor or harsh environments.

 

The LDD-1200H operates over a wide temperature range of -40°C to 85°C and carries CE approval. It is supplied in tubes of 15 pieces. This driver is ideal for constant current LED lighting systems requiring a compact, board-mountable solution.
