★★★★ high reactance autotransformer hid ballast circuit diagram

♔♔♔ High-Reactance Autotransformer Ballast Circuit The High-Reactance Autotransformer Ballast is used when the line voltage in insufficient to ignite the lamp using a . As a result, these ballasts are bigger, heavier, and less efficient than reactor ballasts, but they can be used in a wide variety of applications, because they come with multitap capability. It is very similar to the reactor ballast, but utilizes a two-coil design to step up the startup voltage to ignite the lamp. The coil then acts to regulate the lamp current similar to the reactor ballast. The High-Reactance Autotransformer Ballast typically has 90% + HPF power factor, and 1.4 to 1.6 current crest factor (CCF). Most HX-HPF ballasts are rated to handle supply voltage variations of 5%, which results in a 9 to 12% lamp power variation.

★★★★ reactor electromagnetic hid ballast circuit diagram

♔♔♔ reactor hid ballast circuit diagram The Reactor Electromagnetic HID Ballast is the simplest, smallest, most efficient and most economical type of electromagnetic ballast. The reactor ballast is electrically in series with the lamp. There is no capacitor involved with the operation of the lamp. Because of that, the lamp current crest factor is desirably low, in the 1.4 to 1.5 range. Reactor ballasts feature a simple design, which uses the Line Voltage to ignite the lamp. Reactors are generally used as Normal Power Factor devices. Their highest current draw occurs during starting, which must be allowed for in the capacity of the line. The line current can be lowered by using a capacitor across the line to achieve a High Power Factor of over 90 percent allowing more ballasts per circuit. This ballasts requires an ignitor to start the lamp.

★★★★ hid lamps and ballast circuit diagramhtml

♔♔♔ HID lamps and ballast circuit diagram The term High Intensity Discharge or HID describes lighting systems that produce light through an electrical discharge which typically occurs inside a pressurized arc tube between two electrodes. Light is produced by an arc discharge between two electrodes located at opposite ends of an arc tube within the lamp. Electric discharge lamps have a negative resistance characteristic, which would cause them to draw excessive current leading to instant lamp destruction if operated directly from this voltage. The ballast is therefore utilized to limit this current to the correct level for proper operation of the lamp.

★★★★ constant wattage autotransformer cwa hid ballast circuit diagram

♔♔♔ Also known as lead style ballasts, Constant-Wattage Autotransformer (CWA) ballasts are the most common ballasts used on 175 W or higher MH lamps. It offers the best compromise between cost and performance, means of providing stabilized light output (lamp regulation) as opposed to the Magnetically Regulated circuit. It is a high power factor devise, utilizing a capacitor in series with the lamp. A ??10% line voltage variation will result in a ??5% change in lamp wattage for Mercury, or ??10%
change in wattage for Metal Halide. Below picture shows a typical Constant-Wattage Autotransformer (CWA) HID Ballast Circuit Diagram.

★★★★ magnetic regulator regulated lag hid ballast circuit diagram

♔♔♔ Magnetically Regulated (Mag Reg) and Regulated Lag (Reg Lag) are another type of EM (Electromagnetic Ballasts) HID ballasts. This ballast design is the most sophisticated and provides the highest power regulation to the lamp. They utilize a magnetic with three separate coils. A ballast incorporating this circuit consists of three coils instead of the usual two or one, with the third coil and its capacitor stabilizing the lamp. One coil connects to a capacitor for increased Power Factor and to regulate current into the lamp coil.
