Products Characteristics

 

1.Signal control and pressure function: The battery voltage range, the dropped battery voltage range and the pressure can be arbitrarily set on the touch screen and computer software. When the display value reaches any set value (drop voltage 50mV or pressure The pressure is 800N, square single cell, when the pressure reaches 400N), the pressure of the equipment is maintained for 30S and the pressure is released) The machine automatically stops, the pressure tool stops and starts timing, and the pressure tool automatically stops when the set time is reached. In the original state.

 

2.The battery voltage test and pressure tooling table is placed in the high and low temperature box to complete the test.

 

3.Control method: temperature control touch screen; forced internal short circuit control touch screen, battery, voltage signal, control and pressure function control can be controlled separately on the touch screen or computer software;

 

4.You can directly watch the voltage, pressure, working time and changes in the product test process.

 

5.Pressure unit: N, Kgf, Ib can be selected

 

6.The explosion-proof high and low temperature test chamber has :Fire and smoke function (exhaust gas after the test is completed; exhaust fan is installed on the top of the test) and fire observation window (three-layer explosion-proof hollow glass observation window), explosion-proof pressure relief hole 150*150mm, explosion-proof safety chain on the door, inside the box The lighting is equipped with one (24VLED). One test lead hole (50mm) on the left side of the box and matching high temperature silicone plug. The insulation layer is polyurethane foam.

 

7.Temperature controller: mature control technology; dynamic PID + balance temperature control; minimal temperature fluctuation; color LCD program touch screen control, man-machine dialogue operation interface, set temperature and working time; simple and convenient; high precision and good stability , Precision and durable.

 

8.Intelligent energy automatic adaptation technology; hierarchical refrigeration power control, select French Taikang high-efficiency compressor; energy saving effect is significant.
