2、 Test Conditions:
Temperature: room temperature 25°C.
Voltage: 12 V system test voltage 18 V.
3、 Test Basis:
Per ISO 16750-2:2023 Clause 4.3.2, 12 V system test method.
4、 Test Steps:
1. DUT at room temperature, lit at 13.5 V.
2. Programmable supply outputs 18 V / 400 ms overvoltage pulses, interval ≥1 min, 5 pulses total.
3. Monitor during each pulse: lamp flicker/extinguish and driver reset.
4. After 5 pulses, return to nominal voltage and confirm function self-recovery.
