What are the differences between a magnetic and electronic ballast?
A magnetic ballast uses electromagnetic induction to regulate the flow of electricity to a light fixture, while an electronic ballast uses electronic components to control the current. Magnetic ballasts are typically larger and heavier, while electronic ballasts are smaller and more energy-efficient.
What are the different types of ballast used for fluorescent lights?
The different types of ballast used for fluorescent lights are magnetic ballasts and electronic ballasts. Magnetic ballasts are older and less efficient, while electronic ballasts are newer and more energy-efficient.
Use of electrical ballast in hid lamp circuits?
Electronic ballasts are more efficient than magnetic ones. They use less power, generate less heat, and are quieter. They are also more expensive up front.
What is better choice electronic compass or magnetic compass?
An electronic compass is better, but more expensive and complicated.
What are the differences between magnetic and electronic ballasts?
Magnetic ballasts use coils and capacitors to regulate current flow, while electronic ballasts use semiconductors. Electronic ballasts are more energy efficient, lighter, and quieter than magnetic ballasts.
Is a T8 ballast and T8 bulb more efficient then a T12 ballast and a T8 bulb?
In a T* ballast and T8 bulb more energy efficient then a T12 ballast and a T8 bulb? A:Depends on the CURRENT through the tube. When the Tube is run at 100% of rating, The T12 Takes more CURRENT to give a certain Brightness. Because the surface of the T8 is closer to the ion stream through the tube, it takes less CURRENT to light up the T8 to the same brightness. However, IF you use a T12 in a T8 ballast, you will get LESS CURRENT through the tube, and LESS POWER consumed ALONG with LESS Light.
How repair ballast?
Ballast meaning neon ballast You are dealing with lethal voltages and should never try to repair As ballast It is practically a non repairable item . Usually it is totally burn up and repairing if possible is not cost effectiveNext AnswerA ballast is not a repairable item. Taking one apart, unwinding the coil to find a break and repairing it is not practical. Especially if you had to clean out the tar like sunstance inside it to get at the parts. In a fluorescent tube fixture, the ballast is easily replaceable by a knowledgeable person. The replacement part is not expensive and an old wire coil ballast can be replaced with a more efficient electronic one.A small neon bulb ballast is just a small resister capable of handling the wattage going through it. It is easily replaceable but the bulb is so cheap the it isn't worth the labor. You can just get a replacement bulb.
Why does a Ballast hum?
The obligatory wise guy answer is always "Because it doesn't know the words." If we get by that there are two basic types of ballasts. The traditional electromagnetic ballast hums more than the newer electronic ballast. Fluorescent fixtures have a sound rating that ranges from "A" to "D" with "A" being the quietest. In electromagnetic ballasts the alternating current causes a magnetic field to basically compress the central iron core in a phenomenon called Magnetostriction. What you are hearing is a 60 Hz vibration that can get louder with age. In an electronic ballast the hum is usually much less noticeable and can again come from vibrations induced by the switching happening in the electronic components.Next AnswerThe core of an electrical ballast, like the core of a transformer is made of laminated layers of iron material. This type of construction makes it work more efficiently. The Alternating Current (AC) repeatedly magnetizes and demagnetizes the layers in the core causing them to vibrate. The layers are bound together with some sort of glue limiting the actual vibrations and if properly done there is no humming sound.As the ballast gets older, the glue material weakens allowing the layers to separate and allowing the vibrating layers to hit each other resulting in the humming sound. An old ballast can get pretty loud.
What does the EEC power relay do?
EEC is the electronic engine control, the EEC relay sends power to the electronic engine control. The EEC relay should have a total of 4 wires going to it. Of the two smaller wires only one will have power, and only when you turn the ignition ON. Then if the relay is working properly you will have a completed circuit, creating a magnetic field with in the relay. This magnetic field will make a connection between two more wires that will be larger. Only one of the two larger wires will have power, when the connection is made with the ignition turned on. This will make a connection sending power to the fourth wire and the fourth wire will send the power to the electronic engine control (EEC). Then the electronic engine control will send power to everything the engine needs to run. LLL
What are the different types of fluorescent ballasts available in the market?
There are two main types of fluorescent ballasts available in the market: magnetic ballasts and electronic ballasts. Magnetic ballasts are traditional and less efficient, while electronic ballasts are newer and more energy-efficient.
Will a t 8 fluorescent tube work in a t 12 fluorescent fixture using a high output ballast?
Yes....usually. However, lamp (bulb) life may be somewhat shorter than if the proper t8 ballast is used. Since ballasts limit current flow in the circuit, a mismatched (t12) ballast would cause more current to flow through the t8 lamp than the lamp's design specification. The lamp's output would therefore be brighter in proportion to the additional current. Owners of aquariums and terrariums make use of this property by overdriving both T12 and T8 style lamps with ballasts designed to drive two (or more) lamps to drive a single lamp, therefore supplying 2x or more current to the lamp than its original ballast. This results in a greatly increased light output, somewhat reduced efficiency, and shorter lamp life.
Does a 277 volt fluorescent fixture cost less to operate than a 120 volt fixture?
Not necessarily. It's the wattage of the lamps that determine how much power is used. 277V lighting merely allows for more lights to be on a circuit than if they were on a 120V. The current that is printed on the ballast, times the voltage the ballast is connected to, is what determines the cost to operate the fixture. This is the true wattage of the fixture. The wattage of the lamps are independent as new electronic ballasts can power a numerous amount of tubes of various wattages.
