RECOM Power RCD-48 Constant Current Buck LED Drivers

RECOM Power RCD-48 Constant Current Buck LED Drivers provide a step-down constant current source designed for driving high power LED applications. With an input voltage up to 60VDC and constant current outputs of 350mA, 500mA, 700mA, and 1200mA, the RECOM Power RCD-48 drivers provide power up to 70W. This buck driver is ideal for operation with longer LED-chains and larger multi-chip arrays - perfect for applications like 48V bus lighting solutions or high voltage LED arrays (e.g. high bay lights).

The RCD-48 LED Drivers are dimmable down to zero with external digital (PWM) or analog control. The PWM control input can be directly connected to a microcontroller. Efficiency is rated at 96%, with an operating temperature range of -40°C and +85°C. The modules are available with pins for PCB mounting or with flying leads for non PCB applications. All types are certified to EN/UL-60950-1.
