Dynamic Voltage Regulator
- The integrated design architecture with high environmental adaptability allows for a small number of devices to be used, strong impact resistance and long service life of a single device.
- The use of supercapacitors has a long life and is easier to maintain.
- The power part is modularized.
- The full response time is less than 1 millisecond, ensuring uninterrupted power supply.
- The intelligent over-capacitance management system is used to detect the abnormal state of supercapacitors in real time.
- The wider input DC voltage range gives customers more convenience and optimizes their initial investment.
- It can charge the energy storage element at full capacity, effectively solving the problem of continuous sag landing common in lightning weather.
