select apparatus speciality

System strategy adopt software/hardware combine design,under presupposition of not lossing Technical Data and Performance,simplify hardware,improve reliability, facilitate maintenance  or repairing.

Flash pulse width 0--100 ms continuely adjustable,step per 1ms,suit different cell’s testing.

Region of once flash testing,settable several times testing,settable light intensity on the basis of testing demand at different times,suit different application(optional).

Adopt 2M×4 route high speed synchronic acquisition card, revert clearlier testing curve details,reflect accurately tested cell’s actual working state.

Adopt temperature testing with infrared,  reflect cell’s temperature changeing, compensate temperature automatically

Automatic control,real time detect state of cell and main unit circuit in the entire testing region,providing software/hardware protection,ensure equipment work reliably.    

Select apparatusu unit’s speciality

Control panel		Providing humanistic operating interface,display intuitively equipment’s state, revise or adjust circuit parameter with software in the project menu to avoid revise hardware,easy to maintain,thereby reduce maintenance cost.
Electronic load  board		Solar cell testing’s core circuit. Adopt software control,concise circuit devise,high reliability. voltage,current acquistion circuit adopt high accurate resistance and special galvanometry  amplifier and instrument amplifier.
Acquisition card		Adopt 4 route high speed synchronic acquisition card,every route independent acquisiton ratio reach 2Mbps, Acquire more details of testing curve,acquistion ratio is adjustable according to actual application.
Super capacitance		Adopt German BHC capacitance,life time reach 20000 hours,with good stability.

used in the filtration of solar energy mono-crystalline silicon and the poly-crystalline silicon cell pieces.

 

Through stimulates the solar spectrum lamp-house, carries on the testing and surveys to the cell module related electrical parameter, according to the measurement result classifies the cell piece.

 

It has unique apparatus of modifying, to input the compensate parameter, it will carry on automatically/manual temperature compensation and compensate with the light intensity, and automatically measures and modifies the temperature. 

 

Based on the windows operation surface, and humanized-design testing software, it records and displays test curve (I-V curve, P curve) and the test parameter(Voc, Isc, Pm, Im , FF, EFF), the test of sequence number is automatically produced and preserved to the assigned folder.
