Users may have many testing requirements for PDU testing, in addition to wiring harness testing requirements, there are also some functional tests. For example, contactor function testing, airtightness testing, PDU load testing, component testing and other functions.
Feature:
- Suitable for online full inspection during PDU mass production process
- 8 sets of control cards per control card (multiple cards can be added) for control circuit connection, testing resistance, high-voltage insulation, etc
- 32 points per card (with the option to add multiple cards) for measuring on/off circuits, and can determine the upper and lower limit resistance values for each set of test on/off settings
- 32 points per card (multiple cards can be added) for measuring resistance, and tests the resistance value of each circuit under the measurement conditions of 0-40V 0-2A,
- Minimum resistance display 1uΩ, four wire measurement can display voltage drop
- The equipment can provide a withstand voltage of 0-3.5KV insulation 1KV test before and after the control circuit is closed, and can set leakage current insulation upper and lower limits
- The system provides the communication conditions required for EMS and BMS communication control testing
- Hardin interface for quick replacement
- The equipment adopts pure computer editing, testing, storage and other operations
