The SMR9000 is an integrated test system designed for functional verification of AC charging guns operating in Mode 2. It performs:
1.Function testing (e.g., operational timing, etc.)
2.Protection validation (overcurrent, overvoltage, etc.)
3.Safety checks (e.g., ground fault, power phase sequence error)
The SMR9000 offers three testing modes suitable for various scenarios. For example, in the case of overcurrent protection testing:
1. Lab Mode
2. Precise identification of protection thresholds (e.g., exact overcurrent trip point)
3. Production Mode
4. Rapid pass/fail judgment (e.g., protection response time validation)
5. Self-Learning Mode
6. Automated parameter calibration and test to record indicators and characteristics of the charging gun
The SMR9000 is designed for both R&D verification and production line testing, capable of performing precision laboratory measurements as well as rapid product screening in manufacturing environments.
