DC Ballast

DC Ballast is Direct Current ballast. DC HID ballasts work with DC HID bulbs. It has good and stable performance.
The Low-wattage HID bulb is designed for automotive usage for quick start and hot re-strike. HID ballast follows the 6 operation stages of HID bulb: turn-on, ignition, take-over, warm-up, run-up and steady state. So HID ballast needs not only different control modes for different stages but also complicated timing control.

Specification:

Performance:
1) Light output is stable within ±10.5% during the 125 to 145 second time interval.
2) At steady state, there's minimum variation in color, such as color bursts.
3) It's able to respond to momentary off times of varying periods of time after achieving steady state conditions and thermal stabilization of the bulb.
4) It meets performance specifications when supplied by primary positive input voltages varying from 9 to 18 VDC.
5) It provides over current protection.
6) The system is designed to be compatible with the electromagnetic environment generated by the motor vehicle and its equipment.
