PowerLED Constant Current LED Driver is a two in one dimming function constant current LED driver with an input capability of 180 to 227VAC, or 254 to 392VDC and multi stage constant current output. It has selectable output current, it is also dimmable with either 1-10v or push dimming. The power supply has a synchronisation function, which allows up to 10 drivers to be connected. The output current level is selectable via a dip switch to output with DC voltage range of 6 to 54Vdc at 18.9W or 25.2W of power. The power supply has a synchronisation function, which allows up to 10 drivers to be connected in a master and slaves configuration, allowing LED lighting connected to the drivers to be dimmed through the master unit to the slaves, in synchronisation ensuring seamless control in larger environments. The two in one dimming function means you may select the most suitable dimming style for your installation; the control options available are external 0-10Vdc and PWM signal.
