The power supply voltage through the hps ballast and lamp filament immediately applied to the electronic ignitor poles. 220 volt ignitor immediately make inert gas ionization, glow discharge. The heat of the glow discharge bimetal thermal expansion, the bipolar contacts. Current through the ballast, ignitor contact electrode and filament ends constitute pathways. Filament current was quickly heated, emits a large number of electrons. At this time, since the ignitor poles closed between the poles of the voltage is zero, glow discharge disappeared, the tube temperature is reduced; bimetal automatic reset, poles disconnected. Disconnect the moment at the poles, the circuit current is suddenly cut off, have a great self-induced emf ballast, superimposed upon the supply voltage applied to both ends. When heated filament electron emitted from a large, high voltage across the lamp under the action with great speed from low potential to high potential side terminal movement. In the acceleration process, the argon gas molecules collide tube, so that the rapid ionization. Electronic trigger abnormal protection, in the conventional electronic trigger circuit two ends of the resistor divider branch access delay circuits. When the lighting circuit is abnormal, the bulb end of the pressure was maintained in the power grid voltage exceeds the set time, the metal oxide semiconductor field effect transistor, is not enough to trigger diode, electronic trigger stop working. The main advantage of this utility model is a abnormal state protection after power lamp does not start, stop triggering within 5 minutes, to avoid long-term trigger for light bulbs, electrical accessories and high-voltage shocks trigger itself, affect life expectancy, but also to avoid long-term electrical equipment near strong electromagnetic interference....

Aluminum electrolytic,film,electric double layer,conductive,functional polymer,capacitor. JAMES has a comprehensive line of capacitors in metal cases (up to 525V ratings) and plastic cases (up to 400V ratings). All Universal capacitors are designed for 60,000 hours of continuous life. They’re exceptionally reliable because we put them through accelerated life testing at 125% rated voltage and rated temperature +10°C. A capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. If you have know the battery works, then you know that a battery has two terminals. Inside the battery, chemical reactions produce electrons on one terminal and absorb electrons on the other terminal. A capacitor is much simpler than a battery, as it can't produce new electrons -- it only stores them. JAMES capacitors are normally packaged with ballasts. They may also be ordered separately, bulk packaged, or individually boxed with the suffix “BH” (metal cases only). Capacitor weights vary from 1/4 lb. to 1 lb. each....

JAMES offers 50 Hz core and coil ballasts to meet the rapid growth in demand in international markets. Our ballasts are available for 220, 230, and 240 volt electrical systems. HID ballasts are available to operate the wide variety of metal halide, high pressure sodium and low pressure sodium lamps available in today’s marketplace. Like fluorescent, HID lamps are gas discharge lamps. Light is produced by an arc discharge between two electrodes located at opposite ends of an arc tube within the lamp’s outer glass envelope. The ballast is the lamp’s power supply; its purpose is to provide proper starting and operating voltage and current to initiate and sustain this arc....
