You suspect that a power supply is faulty but you use a multimeter to measure its voltage output and find it to be acceptable Why is it still possible that the power supply may be faulty?
Yes, it can be faulty. Some damaged power supplies show good output voltages on the voltage range of a multimeter but, when you connect them, they don't work properly. One possible reason is that maybe an IC in its voltage regulator has a high resistance between the common and the output. You cannot see this by shunting a voltmeter onto it. You have to place a typical load onto the output to test it.
Can you use 15 watt converter for 9 volt appliance?
Depends on what the output voltage on the converter is.
How do you find out the power rating of your power supply?
In America it should be 60hz. But you can hook up a power meter to the line and find out the real frequency and voltage of the common household or office power line. You may be surprised at the number of spikes and drops in voltage and frequency in a household line. A good UPS can some times tell you as well.
What type of power supply is needed to power the Mitsubishi LT-70 turntable?
i dont know but if you find one could you let me know as i have this turntable and i am looking for the amplifier gerry
Can you use a12vdc 2000ma power supply to power a 12vdc 1000ma device safely?
Depending on what type of power supply it is there are a few options.If the 2000mA rating means it'll supply up to 2000mA, you're already okay, although you should put a resistor in parallel with the device to safely dissipate extra power. You wouldn't want to exactly split the supply in case the device has current demand variations. It would probably be best to siphon off say, 750mA. Since it's 12 volts, from ohm's law: V = IR you'd want 12 = 750mA*R, or a 16 Ohm resistor. It would also have to handle the power output, where P = IV, so P = 12v*750mA = 9 W. This is a lot of power, but you could probably find such a resistor somewhere. (Try looking at sandstone power resistors)However, if the supply is powering a sealed device (eg something you wouldn't open up and tamper with), I think you'd be better off just finding the appropriate power supply.
How do you find power input with given power factor and power output?
Output Power divided by Power Factor.
How can you power a 12V car radio from a 110V wall outlet?
You will have to purchase a power supply with a 12 volt DC output capable of handling the current draw of the car radio. Try "google" to find the manufacturer's specification sheet for the radio. In the specs. will be the amp draw of the radio. With this information you will know what amperage the output of the power supply needs to be.
Can you use 5v 1000ma adapter on a 45v 400ma device?
No you can not. The power supply output of 5 volts is under sized. There is no way that a 45 volt device would operate from it. You will need to find a power supply of 45 volts.
Where Can You Find a 72w Constant Voltage LED Driver AC 90-240V?
This switching power supply is ideal for DIY projects like light bulbs, motors and other electronics. The output voltage is DC 12V constant voltage, which means that no matter what the state of charge on your battery is, this power supply will output the same voltage. This Switching Power Supply is a smart choice for your home or office working environment

How do you find power output?
by using tester
You have spark to your spark plug but you don't seem to have power to injectors 6 and 7 How do you find the power supply for them?
To find the power supply look at a schematic for the fuel injection system in a service manual for the vehicle they are in.
What should you do with a power supply if it is too hot to touch?
Find out what the VA capacity of the power supply is and then add up the connected load in VA (volts x amps). If the load totals are greater that the VA power supply capacity then this is where the heat is coming from. The power supply is overloaded. Remove some of the load or get a bigger capacity power supply.
Where can you find the power supply model U120650A63?
I have one bout to post on ebay im not sure what its for but its ITE POWER SUPPLY MODEL U120650A63 WHATS IT FOR?
Where is a good place to find a Dell Inspiron power supply?
The quickest place to find a Dell Inspiron power supply may be on Amazon. You can also contact your local Dell supplier and ask them for their assistance.
How do you find the wattage of your power supply?
Its usually written on a label on the outside of the power supply box. The number will specify Watts, i.e.150W for 150 Watts
How do you find the input power in the electric efficiency formula if you have the output power and the efficiency percent?
Output equals efficiency times input; in formula, Ot = Ef x In and so In = Ot/Ef. To calculate the original input, divide the output by the efficiency.
