Durable Bench Test

The durability test bench is mainly combined with environmental test equipment(temperature and humidity box、vibrating table、salt spray box、
spray box etc endurance test auxiliary test equipment) then according to the endurance test ISO16750 (which includes high and low temperature
test、vibration test、voltage test、waterproof and dustproof test、safety and service life test etc ) to endurance(DV/PV) test for the controller under test.

Durable Bench Test
—— Overview
The durability test bench is mainly combined with environmental test equipment(temperature and humidity box、vibrating table、salt spray box、spray box etc endurance test auxiliary test equipment) then according to the endurance test ISO16750 (which includes high and low temperature test、vibration test、voltage test、waterproof and dustproof test、safety and service life test etc ) to endurance(DV/PV) test for the controller under test. The endurance test bench provides excitation、load simulation、no-load simulation etc virtual operating environment, Make the sample to be tested run in accordance with the established test conditions, Simultaneously collect the voltage、current etc signal; The enduring test upper computer provides the operating time sequence of the controller under test, And Real-time monitoring and recording of the signal status、error and alarm Information etc, Finally, The test report is automatically generated. This durable bench test system supports parallel testing of multiple tested controllers, Generally based on NI-PXI platform and LabVIEW software development.

Huahai Technology provides a low-energy environmental friendly, safe and reliable durable test bench and test software, Convenient for durability test and performance test of various controllers and parts.
