What is the role of the ballast?

1. It has the performance of cold start current <6.5A (common ballast is 8.5A~9A or higher), and the starting speed is fast. The function of automatically retransmitting the current is designed, which is also called the function of secondary replenishment. Used in different manufacturers to produce HID bulbs with different tube pressures.

2. With voltage design wide voltage performance, generally 7.5V ~ 18V (common ballast is 9V ~ 16V), can ensure that low voltage and high voltage can start normally;

3. When hot start or dimming power supply, the starting current is <5A (usually the stabilizer is 7A or higher), reducing the load on the car due to frequent dimming, and the power supply to other electric devices of the car; Instant load, protect the original line of the car and the car's own protection system; low current start-up speed, eliminate the long-term lighting time due to reduced current, reduce the visual stop interference caused by nighttime dimming; low current start to prevent the bulb from aging or Light decay and reduced interference with other automotive electronics. The low-power power system is also easy to start. The power supply below 10A is enough to start low-power power supply. It can be installed on other equipment such as motorcycles. The temperature is relatively low when working, reducing the bad parts caused by high temperature. Or the possibility of increased failure, reducing the chance of product rework; because of the above performance and the advantages that other products do not have, adapt and match the bulbs of different manufacturers and the performance of the car is stronger.
