Which IC can be used for 100V power supply?
LM317 can be used for regulated dc power supply upto 37V. For more voltage range, a zener can be connected at the reference pin.
What is the effect on the supply current if the capacitor removed?
It depends on how the capacitor is connected and whether the supply voltage is a.c. or d.c. Assuming you are talking about a power-factor improvement capacitor (connected in parallel with an inductive load, supplied with a.c.), then the supply current will reduce.
Why ghost power acting on a circuit?
Ghost power may be acting on a circuit if it has a capacitor or transformer connected. This will supply power long after the input has been disconnected.
What will happen if i connect a power supply of higher current rating to lower current load?
The supply won't have to work as hard. It is perfectly acceptable, for example, to use a 1A, 12v supply to supply a 12v, .5A load. The current rating indicates the ability of the supply to dissipate heat caused by the current flowing. If the load current is above the power supply current rating, the power supply will overheat.
What would be the voltage suplied to each circuit if three circuits are connected in parallel with a power supply of 30 volts?
30 volts.
What is the comm wire on a ballast?
The common wire on a ballast is used to supply power to the entire lighting fixture. It is typically connected to the incoming power source and distributes power to the individual lamp holders. The common wire ensures that the ballast functions properly and all lamps receive the necessary electricity to produce light.
What is a reverse connected 120V ballast?
A reverse connected 120V ballast is a type of ballast that can operate a fluorescent lamp with reversed polarity. This means that it allows the lamp to be connected to the power source in reverse compared to a standard ballast, providing flexibility in certain lighting applications.
If 227v connected to 120v ballast what happens?
If a 227V power source is connected to a 120V ballast, the ballast may get damaged due to the excessive voltage. It is important to always ensure that the voltage input matches the rated voltage of the ballast to prevent such issues.
How can you measure the ampere or watt for power supply?
You can measure the current and power of a 'power supply', using an ammeter and a wattmeter. With the power supply connected to its load, the ammeter must be connected in series with the power supply's input. The wattmeter's current coil must also be connected in series with the power supply's input, and its voltage coil must be connected in parallel with the supply, taking the instrument's polarity markings into account.
How is the power factor meter connected?
power factor meters are connected across the supply
How to remove ballast for LED lights?
To remove ballast for LED lights, first turn off the power supply. Then, open the fixture and locate the ballast. Disconnect the wires connecting the ballast to the fixture. Remove the ballast and rewire the fixture to directly connect to the LED lights. Close the fixture and turn the power back on to test the lights.
Will 277V work with a 120V ballast?
The impedence of the ballast is system voltage dependent to allow required current to pass through the light fixture. If system voltage changes, the current passing through the light fixture changes, therefore to get designed output from the fixture, the ballast has to be changed.
How do you install hid lights?
Generally:Disconnect power supply to bulbPlug in HID Kit ballast unit to power supply to bulb. This may require drilling a hole in the rubber or plastic rear coverSecure Ballast unit to the vehicleRemove old bulbPlace HID bulb in holderConnecting output of ballast to HID bulbThis will vary from manufacturer to manufacturer, and your HID kit should come with instructions.
Power supply units are rated in?
Power supply units are rated based on their output and efficiency. When more equipment is connected, a higher output power supply is needed.
How do you change back to stock head lights from HID lights lpaced by previous owner?
As long as it is a conversion kit, and not a replacement headlamp unit, it should be straightforward.Purchase standard halogen bulbs of the correct fitting for your vehicleRemove ballast unit that is connected to the HID bulbs. In most cases, they are powered only from the lighting power supply. Disconnect the cables to the bulbs and to the lighting power supply.In some cases there may be an additional power supply from the battery to the ballast. This can also be removedRemove HID bulbs from the holdersInsert replacement Halogen bulbsThe lighting power supply should connect directly to the new bulbsIf the power supply does not connect, the holders or wiring may have been modified, and replacements would need purchased.
How do you ignite a 400w electronic metal halide or high pressure sodium bulb?
To ignite a 400W electronic metal halide or high pressure sodium bulb, you need to ensure that the power supply is connected and turned on. These bulbs require a ballast to regulate the electrical current, so make sure the ballast is functioning properly. Once everything is set up, simply turn on the power switch, and the bulb should ignite.
What happens to charger if kept in power supply and not connected to phone?
Nothing should happen except for the loss of the time to charge your phone with it after a couple hours, you should unplug it.
