The LDC-55DA is a constant current LED driver manufactured by Mean Well USA, designed for LED lighting applications requiring precise current regulation. With a power rating of 55W and an output current of 1.6A, it delivers a constant current across an output voltage range of 27 to 56V, suitable for driving series or parallel LED arrays.
The driver operates from a 180VAC input and features an AC-DC converter topology with a high efficiency of 90%. The DALI dimming interface enables digital control for adjustable lighting levels. Protections include over-temperature (OTP), over-voltage (OVP), and short-circuit (SCP) for reliable operation.
Packaged in a slim form factor measuring 320mm x 30mm x 21mm, the driver uses a terminal block termination style for secure wiring connections. It is designed for an operating temperature range of -25°C to 80°C, making it suitable for indoor and outdoor applications with appropriate thermal management.
Approvals include CB, CCC, CE, and cURus, and the product is RoHS3 compliant. The output voltage range and constant current output make it a versatile choice for various LED luminaires.
