CHT9960 PV Junction Box Tester
The CHT9960 PV junction box tester is equipment specially designed for electrical characteristics of PV junction box. It can be used to test the internal diode voltage drop (VF), reverse leakage current (IR), reverse voltage (VR), conduction of DC resistance(R), and the temperature parameters (TC). CHT9960 meets the test requirement of 10W~400W junction box (with 2~8 diodes) and is widely used in the on-line testing of junction box manufacturers and purchase acceptance of PV modules users.
The newest programmable switching mode power supply design makes CHT9960 very portable to have strong function.
Standard equipped with RS232C and HANDLER interfaces, CHT9960 can realize automatic measurement.

Feature
 Forward voltage/Insulation resistance / Leakage current/ Temperature / Low resistance
 Switching power supply design, small size with multifunction
 The PLC interface, production line sorting
 Document management, U disk storage
