Description
To get the very best out of your LED lighting solution, in terms of brightness stability and control, the lights should be driven from a current source, not a nominal voltage supply. The Gardasoft pulse / strobe controllers are current sources. The PP420 LED lighting controller offers four output channels which are independently controlled.
Each channel can be individually configured to output continuously; or pulsed based on an external trigger signal or internal timer. The ‘F’ version controller will allow pulse width control down to 1µS resolution. Selected mode allows switching of the light based upon the state of an external trigger.
