After switching on the mains the filter capacitor C2 and the bulk capacitor C10 are charged to … An electrical ballast is a device placed in series with a load to limit the amount of current in an electrical circuit.. A familiar and widely used example is the inductive ballast used in fluorescent lamps to limit the current through the tube, which would otherwise rise to a destructive level due to the negative differential resistance of the tube's voltage-current characteristic. As known in the art, switches 16 a and 16 b alternately conduct current. It reveals the elements of the circuit as streamlined shapes, and the power and also signal links in between the devices. This simple 40 watt emergency tube light circuit permits one to hook up a fluorescent tube up to 40w in a vehicle or any other 12v source. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow. It is not dimmable and works at 110/120VAC. I also do some graphic and web design. Electronic circuit on the circuit drawing 12V DC fluorescent lamp above the ballast transformer instead of the conventional fluorescent lamp lighting techniques. known as a ballast. Weight (Kg/LB.)

Regulator Ballast. It's a circuit you can put together from junk box components and is a very simple to build. To drive the tube lamp, we need high voltage to make the gas inside the tube get ionized. I constructed it as a push-pull inverter with MOSFETs. The SYLVANIA 49947 electronic fluorescent ballast operates (4) F32T8 lamps at 120/277 input volts. The tube just needs a voltage kick across the electrodes to establish an electrical arc. This kick is provided by the lamp's ballast, a special sort of transformer wired into the circuit. Some non-limiting examples of ballast 16 are rapid start electronic ballasts, instant start electronic ballasts, magnetic ballasts or a hybrid containing components of both the electric and magnetic ballasts.
