FUSIONSEEKER DS-50D5

 

 

 

Introduction

 

    FUSIONSEEKER DS-50D5 is a universal sensory solar tracker controller designed to be used with all dual-axis solar trackers (low concentration ratio solar concentrators included) that use permanent magnet DC motors for moving. Its superiorities are high tracking accuracy, great electrical capabilities, high reliability, long expected life time and also watertight "2in1" polycarbonate housing that serves as a "shadow maker" for sensors and as an all weather resistant protection for electronics. Installation is also very simple - because all components are packed in one "2in1" housing. You just fix it on to the solar "receiver", connect to supply voltage and motors and that's it. And don't forget it's maintenance free - install and forget!

    The heart of FUSIONSEEKER DS-50D5 is its 100% solid state (no moving parts inside, no potentiometers, no relays!!!) and software free (all features are implemented with pure hardware - no reset buttons, no Windows blue screens!!!) electronics that for functioning needs so little power that energy consumption (about 0,002 kWh per day) can simply be ignored. DS-50D5 is working on a principle of equalized output signals of its four light sensors. Two of them are used for azimuth tracking and the other two are used for elevation tracking. The azimuth and elevation tracking principles are identical, so it's enough to describe just, for example, azimuth tracking. When output signals from two azimuth tracking sensors are different (solar "receiver" is not faced precisely to the sun - "2in1" housing is shading one light sensor) electronics, with the help of POWER MOS-FET transistors, turns on the azimuth motor and keeps it running. Immediately after output signals from sensors equalize (solar "receiver" is again faced precisely to the sun) the azimuth motor is turned off and with the help of electronic brake instantly stopped. This electronic brake is in function always but it becomes absolutely necessary in case you set DS-50D5's accuracy to highest level (without brake system oscillates!). This sequence is repeating throughout all day till sunfall when tracker (motor) stops facing to the west. Elevation tracking works in the same way (independently!) only that elevation sensors and elevation motor are in function.

    Next morning when first sun rays appear DS-50D5 with its additional (fifth) bottom sensor notices that and turns on the azimuth motor to move the tracker to the east. After some 5 minutes (it depends on the speed of tracker's rotation) tracker is facing to the east and sequence described above starts to repeat again.

    In case when clouds cover the sun DS-50D5 can stop tracking or it can turn solar tracker towards the brightest cloud - that depends on what tracking accuracy you choose (set). And immediately after clouds disappear it will in every case turn the tracker toward the sun. In short, FUSIONSEEKER DS-50D5 is a solar tracker controller that will always satisfy all your dual-axis sun tracking needs.
