2 Standardoutput currents available are 300mA, 350mA, 500mA, 600mA, 700mA, 1000mA and 1200mA to make thisdriver compatible with a wide range of LEDs applications. Despite its compact size, the RCD series is fullyfeatured with very high efficiency, wide input voltage range, high ambient operating temperature and two meansof dimming: PWM/digital control and analogue voltage dimming. Both dimming controls are independent and canbe combined. The driver is also designed to be as reliable as the LEDs it is driving, even at the full operatingtemperature. Options include an IP67-rated wired version (/W) and a version with built-in reference output vol-tage (/Vref) to power sensors or for easy analogue (VDC)(mA)(Vmin-Vmax) (a)(b) + AnalogueVrefPins or (a)(b) + AnalogueVrefPins or (a)(b) + AnalogueVrefPins or (a)(b) + AnalogueVrefPins or (a)(b) + AnalogueVrefPins or (b)6-36V0-10003-31 Digital + AnaloguePins or (b)6-36V0-12003-31 Digital + AnaloguePins or Wired(a)(b)Standard is no suffix with PCB Pins.

3 (a)Add suffix /Vref for pinned version with Vref output and analogue dimming(b)Add suffix /W for wired version without dimming control (four wires)(b)Add suffix /W/X1 for wired version with analogue dimming control (five wires)(b)Add suffix /W/X2 for wired version with PWM dimming control (five wires)(b)Add suffix /W/X3 for wired version with both analogue and PWM dimming controls (six wires)(a)Add suffix /W/Vref for wired version with Vref output and analogue dimming (six wires)Derating-Graph(Ambient Temperature) !
