Information

New energy vehicles are a major trend in future development. The TH9520 comprehensive test system is tailor-made for new energy vehicle motor tests. It can test up to more than 100 channels, which greatly improves the shortcomings of the original single machine with only 8 channels.
This system can measure insulation, AC and DC withstand voltage, on-resistance, inductance, capacitance, and turn-to-turn withstand voltage. It is small in size and easy to operate. It can automatically save test data, improve customer test efficiency, save workstations, and reduce labor costs. .

Solution Details,

Testing requirements:
1. Insulation withstand voltage between UVW three-phase and chassis
2. On-resistance of UVW three-phase
3. Insulation withstand voltage of temperature sensor and case
4. On-resistance between temperature sensor and case

TH9520 single host is equipped with three channel scan boxes to form a 30-channel motor comprehensive test system. There are two high-voltage relays in each channel, and the four-terminal measurement method can be used when measuring the on-resistance, which greatly improves the measurement accuracy of the product.
