★★★★ 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.

A Complex and Comprehensive Process-car Alarm Installation

The Car Alarm just senses a motion and an electric current and when it starts alarming it will detect someone tampers with your car and there by warns the intruder in a stern voice that there is an alarm set and he will be in trouble. When the car senses a repeated and a heavy shock the voice shouts at a warning at a 127 db and the siren completely sounds for 30 seconds.

A complex and comprehensive process, Car alarm installation requires expertise in working with electrical systems. Systems like Car Stereos, Car Alarm System, GPS Navigation Systems are becoming very much common these days. The ability to read wiring schematics and making strong connections is an added advantage. Additionally, time and patience are the best partners when trying to install an alarm in your car.

There are number of accessories that have to be associated with car alarm system which includes a trunk pin, door pins, hood pin, door sensors, air horns, tilt sensors, starter disable relays, power window control modules, trunk release modules, starter-kill protection, output for parking light flash, door opening protection, adjustable shock sensors, LED lights, and sirens.

You need to locate the suitable location, for car alarm installation which consists of alarm, siren, reset switch, and dash light. You also need to collect the materials such as knife, crimps, solder gun, test light, screws, tie wrap, solder drill, material, screw bit, double-sided mounting tape and a voltmeter. The installation guide coming with the car alarm should be read properly because it consists of complete information about fitting instructions and wiring diagrams.

LED positioning, wiring integrity, alarm module placement are the most important features of any car alarm system. The alarm works more efficiently with strong wiring connection. The effectiveness of the alarm is increased by Hiding of the wiring and exposing of the alarm module placement. The alarm wires are easily visible for a thief can cut them fast and damage the alarm. The installation of LED lights is very important especially as a means to prevent robbery. The LED should be placed in a highly visible and logical position.

The performance of the alarm is tested after the installation process gets completed. The wiring connection should be checked and tried The car alarm installation is done by number of companies who also provide video clips about the actual installation processes, proper testing procedures, and troubleshooting tips.

Manufactures such as Cobra, Clifford, Viper, Toad, Gemini and GT have introduced new car alarm system fitted to your vehicle which would integrate with your existing central locking system so that the remote control will both arm and disarm the alarm at the same time as locking and unlocking the doors.

There are other car alarms too like Cobra OEM alarm which simply plugs in without the need to cut wires or make manual connections. There are newer vehicles too making the car alarm installation quick and simple as they have plugs and sockets placed in the wiring loom.
