The PP500/520 series provides control of LED lighting for machine vision applications and include the power regulation, intensity control, timing and triggering functions required for machine vision systems.

The benefits of SafeSense® technolgy
To obtain the very best fom LED lighting, in terms of brightness, stability and control, the lights should be driven from a current source, not a nominal voltage supply. Driving the LEDs with a constant current source allows for very precise overdriving and Gardasoft's patented SafeSense® technology ensures that the pulse width and duty cycle are kept within safe working limits while protecting the lights from damage. SafeSense® regulates the pulse-width timing and duty cycle, depending on how high the light is being overdriven with the end result of much more light being gained.

Continuous monitoring for fault detection
The PP500/520 monitors the output voltage and current continuously for sudden and long term changes. When an unexpected change occurs, a fault is alerted and the output is disabled. The controllers can detect lighting that fails open or short circuit, lighting which is overheating or degrading over time, and single LED failures, depending on conditions.

Operation
Three modes of operation are provided separately for each channel and each 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 free, downloadable software or by by accessing the controller via internet browser and receiving full access to all of the parameters. The PP520 models also have a simple command set that allowing easy communication with a third-party software package.

All settings are stored in non-volatile memory and these settings will be retained these even when the Ethernet connection is disconnected.

The advantage of Ethernet technology
With the introduciton og GigE cameras, the machine vision market is moving towards Ethernet connectivity. The advantage of Ethernet is that it is fast, long distance, standardised worldwide and implementation is inexpensive.
