FUSIONSEEKER DS-100S10 is a universal ultra high accuracy sensory solar tracker controller designed to be used with all single-axis solar trackers (high concentration ratio solar concentrators included!!!) that use permanent magnet DC motors for moving. Its superiorities are ultra high tracking accuracy, great electrical capabilities, ultra high reliability, long expected life time and also watertight "3in1" pure aluminium housing that serves as a heat sink for POWER MOS-FET transistors, 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 "3in1" housing. You just fix it on to the solar "receiver", connect two wires to supply voltage and other two wires to motor and that's it. And don't forget it's maintenance free - install and forget!

    The heart of FUSIONSEEKER DS-100S10 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 0,001 kWh per day) can simply be ignored. DS-100S10 is working on a principle of equalized output signals of its two light sensors. When output signals from sensors are different (solar "receiver" is not faced precisely to the sun - "3in1" housing is shading one light sensor) electronics, with the help of POWER MOS-FET transistors, turns on the motor and keeps it running. Immediately after output signals from sensors equalize (solar "receiver" is again faced precisely to the sun) the 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-100S10's accuracy to ultra high level (without brake system oscillates!). This sequence is repeating throughout all day till sunfall when tracker (motor) stops facing to the west. Next morning when first sun rays appear DS-100S10 with its additional (third) bottom sensor notices that and turns on the 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-100S10 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-100S10 is a solar tracker controller that will always satisfy all your single-axis sun tracking needs.


Technical specifications





Supply voltage (DC):

Uin = from 10V to 100V DC covered with three selectable input voltage ranges:

Voltage range A: Uin = from 10V to 25V

Voltage range B: Uin = from 20V to 50V

Voltage range C: Uin = from 40V to 100V

Factory defaults: voltage range B

Accepted (applicable) supply voltage sources: Any external power supply or battery or solar cells

Output current (max. motor current):

Iout,cont. = 10A (continuous load!!!)

Iout,10s = 15A (up to 10 seconds)

Iout,max = 45A (short duration - for motor startup)

Output voltage (motor voltage):

Uout = Uin - 0,9V at Iout = 5A

Uout = Uin - 1,8V at Iout = 10A

Electronics self consumption:

at Uin = 12V just 0,8mA

at Uin = 24V only 1,3mA

at Uin = 48V only 1,3mA

(and intelligently built electronics consume always the same without regard to DC motor being in operation or not!)
