Production of temperature rise tester

Introduction：

Connector temperatureThe heating cycle test bench is based onGB/T5059.3-1997、GB2099、GB7251、GB11022、GB11918、GB13140、GB14048、GB15092、GB15287、 Developed based on the current and temperature rise testing methods for electronic connectors and relevant standards for other electrical accessories, it can be applied to ground resistance testing, temperature rise testing of appliance switches, plugs and sockets, switchgear, busbars and other products. It has the characteristics of easy operation, accuracy and reliability, and is widely used in manufacturers, quality inspection and scientific research departments. It can also be used to assess the surface heating of electrical accessories when connected to load current, and whether the electrode temperature rise meets the standard requirements.

1、 Product Overview:

Temperature rise tester, connector temperature rise thermal cycling test benchMainly composed of constant current source (optional), electric voltage regulator, current transmitterComposed of PLC programmable controller, current sensor, current converter, touch screen human-machine interface, and movable chassis.

Connector temperature rise and thermal cycling test benchIt can stably output test current, eliminate the influence of power supply voltage fluctuations, connecting wires, and changes in sample resistance on test current, and improve the accuracy of test results. This power supply has low loss, high efficiency, easy operation, and complete control and detection functions. The computer can display current values, test time, temperature, and temperature time curves, which can be queried at any time.
