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 PP800 series LED lighting controller offers eight output channels which are independently controlled.
You have two options regarding communication; RS232 (PP860 range) or Ethernet (PP820 range). The standard versions offer a maximum pulse current of 20A. There are other options which reduce the maximum pulse current to either 2A or 5A. The lower maximum pulse current gives you much finer resolution control over the output current. There are also other optional controllers within the range (suffixed with a C) that give even greater control resolution on the output. Each channel can be individually configured to output continuously; or pulsed based on an external trigger signal or internal timer. Selected mode allows switching of the light based upon the state of an external trigger.
The PP800 models can be quickly configured using our free software which can be downloaded from this page, or for the PP820 Ethernet enabled controller range 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 PP800 range 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 or RS232 connection is disconnected. Gardasoft Controllers are universally compatible with LED Vision lighting, from manufacturers such as CCS.
When overdriving 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 RT800 series controller, which has all of the features of the PP800 series but is based around our SafePower™ technology. The RT series will also offer you all the advantages of our patented SafeSense™ technology which is not available in the PP800 range. The Gardasoft White Paper on LED Controller technology is a useful reference for the principles of attaining maximum performance for Machine Vision illumination.
