Gardasoft LED Pulse Controller PP500


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 controllers are current sources. The PP500 LED lighting controller offers two 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.

The PP520 models can be quickly configured using our free software which can be downloaded from this page, or simply by accessing the controller via your internet browser; type in the IP address for the controller into your browser and you have full access to all of the parameters. If you are using a third party software package the PP520 has a simple command set that is detailed in the manual allowing easy communication. As with all Gardasoft products, all the settings are stored in non-volatile memory, and it will retain these settings even when the Ethernet connection is disconnected.

Using our patented SafeSeries™ technology, the PP500 controller allows you to overdrive your LED lights safe in the knowledge that the lights will be protected from damage. SafeSense™ regulates the pulse width timing and duty cycle, depending on how high you are over-driving the light. The end result is you get the maximum light possible for your application. Gardasoft Controllers are universally compatible with LED Vision lighting, from manufacturers such as CCS.

If you’re over-driving you may need to increase the DC power input to the controller or heat-sink the controller due to power dissipation. If this is an issue for your application we would recommend the RT200 series controller, which has all of the features of the PP500 controller but is based around our SafePower™ technology.
