What type of device is used with microprocessors to supply special voltage levels for different types of microprocessors that might be installed?
A regulated power supply
What type of transformer is used in a phone battery charger and its ratings?
Usually these "wall wart" chargers are small switching regulated power supplies, not transformers. A transformer may be part of the switching regulator circuit, but it is only one small part of it.The ratings of the switching regulated power supply will vary with different types of phones, but are always printed on a label on the "wall wart" casing. Read the label.
Difference between regulated and non-regulated power supply?
Important considerations when choosing power supplies are type of output, regulated or unregulated. Regulated means the Voltage will stay constant (at least while the supply is operating within its specification) irrespective of the load. Unregulated supplies tend to have higher outputs than stated and are normally used with equipment that has it's own internal regulation circuitry. If in doubt always choose a regulated supply. Using Voltages higher than recommended for a particular piece of equipment may cause permanent damage. Where Wattage or VA rating is quoted this often refers to the total wattage available for a power supply. This figure is mostly used for multi rail units, so that when the VA is calculated for each output and then added together, the total Wattage / VA should not exceed the makers rating.
What type of waveform is produced by Ferroresonant power supply?
ferro-resonant power supply?
A power supply receives what type of power?
It depends on the type of power supply. A power supply used in a desktop computer is generally supplied with AC (Alternating Current) and produces several levels of regulated DC (Direct Current) voltages required by the electronic circuits.
How do I decide what type of power supply I need when I'm building a desktop PC?
Power supply is dictated by your motherboard, simply get the power supply which matches the motherboards pin configuration.
What type of electricity is output FROM the PC power supply?
Direct Current or DC after it leaved SMPS (Switched Mode Power Supply). On a laptop computer the charger/power supply is a single voltage, around 19 volts DC (depending on model no.) On desk top computers, the PC Power supply has several different DC voltages and different wattage capacities. They are +5v +12v - 12v -5v +3.3v Loads of different coloured wires and plugs take the power to the motherboard, hard drives, optical drives and some graphics cards.
Are there any connectors your system needs the power supply doesn't have?
Most often, power supplies for any type of equipment is givin to you when you buy what the power supply is for.
Where should ac or DC supply be used?
The type of power supply being used (AC or DC) should match the power requirements of the device it will be supplying power to.
What is the advantage of using a switching power supply over linear power supply?
A: Assuming the same power output the switching type will be lighter in weight and less bulky.
What type of power supply converts enegry efficiently?
Active PFC
What is the first step you should take when testing a power supply?
You first have to know the type of power supply your are testing. Then you could test whether the power supply is receiving anything from its source. Next check if it is giving any output.
