    Electronic Load Bank Customer Deployments
    1. Renewable Energy – Solar PV modules Safety Testing
    Used to test the safety parameters of PhotoVoltaic modules such as Withstand Voltage, Insulation and Ground continuity detection. This 3-in-1 test apparatus is designed to match the assembly line, which saves space and improves test efficiency significantly.

    2. DC Power Supply – Batteries Short Circuit Testing
    Used for short circuit testing and contact detection in Lithium Ion/Polymer battery cells and related battery packs. The load bank helps to detect the insulation degree of two tabs, tabs and separators.

    Small metal particles or other defects present in the winding of the soft-pack battery may cause a slight short circuit of the objects under test. Direct application of high voltage could cause the metal particles to fuse or the defects to burn and show a good insulation test, resulting in misjudgment.

    The traditional test method requires two testers to complete this test process. The unique panel calling function of our Electronic Load Banks makes it possible to use just one device to complete the same testing, thus resulting in major cost saving.

    3. PCB – Multiple Reliability Testing functions
    Used to perform multiple reliability tests on Flexible PCBs such as Continuity test, Short Circuit test, High voltage continuity test, High current continuity test, Insulation withstand voltage test, NTC thermistor test with a single load bank test apparatus.

    Since the programmable load bank acts as a single integrated testing device, it results in significant reduction in testing time, greater production efficiency and control over product quality.

    4. Electric Vehicles – Comprehensive Testing of Charging Guns
    Our high-voltage wire harness test equipment is used to test the quality of charging guns used in renewable energy driven vehicles such as EVs. The electronic load bank acting as a single integrated test device can handle multiple tests such as Continuity test, Short Circuit test, High Voltage continuity test, High current continuity test, Insulation, Withstand voltage, NTC thermistor test, solenoid valve grounding test
