Description
The RCD-48 series is a step-down constant current source designed for driving high power LED applications.
Four output currents are available. The maximum output voltage is 56V. The buck drivers have digital PWM
and/or analogue voltage dimming control and are special featured with very high efficiency. Typical applications
are 48V bus lighting solutions or high voltage LED arrays (e.g. high bay lights).
