FUSIONSEEKER DS-50D6

 

 

 

Introduction

 

    FUSIONSEEKER DS-50D6 is a universal sensory solar tracker controller designed to be used with all dual-axis solar trackers (solar concentrators included) that use permanent magnet DC motors for moving (with additional external relays/drivers other types of tracker’s motors or hydraulics drive systems can also be controlled by DS-50D6). 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 it to supply voltage and motors and that's it. And it’s maintenance free - install and forget!

    The heart of FUSIONSEEKER DS-50D6 is its 100% solid state (no moving parts inside, no potentiometers, no relays!!!) and software free (all features are implemented with pure hardware – no computer hang-ups, no reset buttons!!!) electronics that for functioning needs so little power that energy consumption (about 0,002 kWh per day) can simply be ignored. DS-50D6 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-50D6's accuracy to highest level (without brake system oscillates!). Elevation tracking works in the same way (independently!). This sequence is repeating throughout all day till sunset when tracker (motor) stops (tracker is facing to the west). At this point DS-50D6 offers you 2 options for turning the tracker back to the east. If you choose the first option DS-50D6 will early next morning with its additional (third) bottom sensor detect first sun rays and immediately turn on the azimuth motor to move the tracker to the east. After some 5 minutes (it depends on tracker’s rotation speed) the tracker will be facing to the east and sequence described above will start repeating again. In case you choose the second option DS-50D6 will after sunset with the help of its additional (third) bottom sensor detect that the evening has come (low light conditions) and turn on the azimuth motor to move the tracker to the east. After some 5 minutes (it depends on tracker’s rotation speed) the tracker will be facing to the east and it will stay there all night. In the morning when first sun rays appear tracking sequence will start repeating again.

    In case when clouds cover the sun DS-50D6 can stop tracking or it can turn solar tracker towards the brightest cloud - that depends on what tracking accuracy (sensitivity) you choose (set). And immediately after clouds disappear it will in every case turn the tracker toward the sun. In short, FUSIONSEEKER DS-50D6 is a solar tracker controller that will always satisfy all your dual-axis sun tracking needs.
