General requirements
HPS Ballasts for high pressure sodium lamp fittings, its performance and quality will have a direct impact on the life of the high-pressure sodium lamps, the luminous efficiency and self-extinguishing. High pressure sodium ballasts requirements for the power loss is small, easy to install, strong, waterproof, anti-corrosion and safety performance...

Fluorescent tubes must have ballast to work, not directly connected to the mains. Start fluorescent ballasts give the lamp startup voltage, lamp start voltage is very high, such as a 36W T8 lamp start voltage exceeds 800V mains only 220V impossible to start. Started, ballast a stable and lamp current,...

(1) energy-saving. Electronic ballasts for fluorescent lamps, multi-use 20 ~ 60kHz frequency supply lamp, lamp light efficiency than the frequency increase of about 10% (by 4 feet in length lamp), and its low power consumption, lamp total the input power is decreased by about 20% better energy-saving effect....

When the switch is turned on, the power supply voltage is immediately added to the two poles of the starter through the fluorescent ballasts and lamp filament. 220 volts immediate starter inert gas ionization, generating a glow discharge. This process heat the bimetal thermal expansion, because the degree of expansion of the dynamic and static contact piece, U-shaped movable contact piece expansion elongation, in contact with the stationary contact piece turned circuit Then the ballast bipolar contact. Current through the ballast, a starter touch the pole and both ends of the filament path....

The HID electronic ballasts and the lamp, the combination of the effective utilization of the input power, in some places, also expressed as Watt / VA or COSΦ of. Generally the inductance ballast high pressure sodium electronic ballast
PF 0.5, even after capacitor correction can only reach about 0.8 electronic ballast can usually do from 0.95 to 0.99, its significance is that you make full use of every watt of power plants confessed, and the Environmental Protection made outstanding contributions....

The HID electronic ballasts & HID magnetic ballasts pros and cons:
1, to ensure that the lamp life: high pressure sodium magnetic ballast aging or deterioration, they provide current may be too large, easy to damage the lamp, resulting in shortened life expectancy, the the CDM lamp price is quite high, the use of electronic town The flow is relatively easy to ensure lamp life. Therefore, as long as there are at 5,000 to replace the lamp records, use the electronic industry than traditional cost-effective....

1, One by one, electronic ballasts for light box is divided into a total of six varieties of 20W, 30W, 40W electronic ballasts
2, one with two,electronic ballasts divided into 2 X 20W, 2 X 30W, 2 X 40W total of six varieties
3, the ring-shaped lamps with electronic ballasts is divided into 22W, 32W, 40W of three varieties
4, quartz germicidal lamp ballast applicable to 35-60W of a variety
Note: 20W, 40W is for the tube, T10, T12, 18W, 36W for T8 lamps. So sometimes we talk about 20W, can also be understood as a 18W T8 tube 36W can also be understood as the 40W T10, T12, because the electronic ballast is generic....
