The PP480 LED lighting controller is high speed constant current controller, enabling milliamp scale control within microseconds. It offers four output channels that are independently triggered and controlled.

PP series controllers are popular in applications where the customer can specific a power supply with a non-standard voltage, to meet the demands of more cost sensitive applications. These are typically (but not limited to) OEM applications that require higher numbers of lighting channels.

Each channel can be individually configured to be pulsed' in response to one of four external triggers or an internal timer. Alternatively, ‘continuous' mode facilitates continuous illumination, and ‘switched' mode allows on/off control based upon the state of an external trigger. Brightness is settleable in all modes.

The PP480 model can be quickly configured using our free software, GardasoftMaint, which can be downloaded via the software tab in this page, or by simply by accessing the controller via your internet browser; type the IP address for the controller into your browser to gain full access to the lighting parameters. If you are using third-party software, or interfacing to industrial equipment such an PLC, the PP480 has a simple ASCII command set, as detailed in the manual, to enable easy communication using either UDP/TCP over Ethernet, or RS232. As with all Gardasoft products, all the settings can be stored in non-volatile memory, for standalone operation.

Using our patented SafeSense™ technology, the PP480 controller allows you to overdrive your LED lights, while protecting them from damage. SafeSense™ manages the relationship between pulse timing, current, and duty cycle, at any overdrive rating. This results in the maximum light possible for your application, whilst maximising the longevity of the LED. Gardasoft Controllers are universally compatible with passive LED lighting, from manufacturers such as CCS.

Unlike our HT, RT, and RC series lighting controllers, which contain inbuilt DC/DC voltage conversion, the PP480 is an entirely linear circuit design. It is OEM orientated controller that requires special attention to power supply voltages and heat dissipation. Therefore, we recommend reading all technical literature before purchase. The Gardasoft team are ready to help at and training is available.
