Can 3 point 5 volts be used instead of 3 volt power supply?

It can be used instead of three volts, if it is not very demanding.

If the voltage requirements are particularly strict, it cannot be replaced, and the general voltage fluctuates, which is normal.

In principle, no, because if the voltage is not consistent, it may cause damage to the relevant electrical components, but how to say that? There is not much difference between you, I don't think there is much of a problem.

It can be used, but it must be used after voltage stabilization, if the electric current is not large, it can be used after the voltage reduction can be used through the resistor, such as lighting the LED lamp can be connected in series with a 100 ohm resistor. If the current of the electrical appliance is large, it can be solved by using a stabilizer block. It cannot be used directly, and the input voltage of general electrical appliances cannot exceed 20% of the rated voltage, and if it is used directly, it will not burn out the electrical appliances.

Volt chargers can replace 5 volts, but the charging speed is slower, in fact, they can be used.

Well, actually, volts, of course, can replace three-volts, this power supply is completely fine, if he is the one in that has this situation. It's completely replaceable.

If it's not a precision instrument with strict requirements, it doesn't matter if it's a precision instrument with strict requirements, it may not work, I don't know where you use it, if you use the radio, it's definitely OK.

Volt, if used in a short time instead of a three-volt power supply, after all, it can also be larger than 1 6 power, if used for a long time, it will definitely damage the electrical appliances.

It depends on whether your electrical equipment is very sophisticated, and the range of its applicable voltage is not included. If it is out of range, it is theoretically not possible, but it can be used if the electrical equipment is not very sophisticated.

It can be used instead of a 3V power supply, but it is generally a small power, and it cannot be used as a substitute for high power.

Some can and some can't, depending on how much voltage the electrical equipment can bear. Generally, there is no problem with high height, and individual ones can cause heat damage.

It is best to use only three volts, which may be too large to hurt the electrical appliances.

A volt power supply can be used instead of a three-volt power supply. The premise is to determine the allowable power supply of the circuit.

Volts in most cases can be used instead of three volts of power supply, because basically it is about the same.

No, it's 166% of the rated voltage, which is too high.

Volt, I think it can be used as a substitute for Sanfu power supply, if it is small, you can't bring it.

It can be used if the general voltage requirements are not high.

This is not to be used, because if the yardage is different, it may cause a fire or cause a certain dangerous behavior, so it cannot be used in this way.

This should be able to replace the 3V power supply, and this should be a little higher and the voltage should not have any effect on the mechanical carbon.

It is not easy to burn out electrical equipment.

If you want to replace it, you can also do it, but relatively speaking, his forest will be slower, and you still have to pay attention to the tax situation.

As long as the equipment will power requirements are not too strict, it can be used.

Can Gofuku be used instead of coral current? I think it should be okay, because his arc is a little bigger than his three-core one.

Warm, volts can replace 3 volt power, not to 6 volt power.

Volts can be used instead of a three-volt power supply, because within its capacity range.

The 24V power supply cannot be directly connected to a 12V electric fan.

Because the power supply voltage is more than twice the voltage of the electric fan, the electric fan will be burned immediately after connection. You can use an LM7812 three-terminal regulator, according to the law of series circuits, so that each fan is assigned a voltage of 12V, reaching the rated voltage of the fan, and then connect the electric fan.

The power supply of a 24V computer case cannot be directly connected to a 12V fan, because the voltage is much higher than the rated voltage of the fan, which will cause the fan to burn out.

Solution: You can connect the 12V fans of the two chassis in series, and then connect the 24V power supply. According to the law of series circuits, the voltage assigned to each fan is 12V, and when the rated voltage of the fan is reached, it can work normally.

Didn't understand your question. If you want to ask if a 12V fan can use 24V power, of course not. If you ask if a 12V fan can be used with a cooling fan for a 24V power supply, I think it should be fine.

If you want to use a 24V power supply to drive a 12V fan, then you should connect 2 fans in series.

Fart, people ask if the 24V fan can be connected to the 12V power supply, and they don't ask if the 24V power supply can be connected to the 12V fan. Just know that you can't, you can see clearly, is it ...... you have something wrong with your eyes

The one behind the computer will definitely be able and won't burn. It's better to get two.

No, it's 166% of the rated voltage, which is too high.

It depends on the nature of the electrical appliances, if it is a motor or the like, it does not matter, if it is a precision circuit, it will definitely not work.

With a voltage divider resistor, it is possible to stabilize the DC from 5 volts to 3 volts.

Calculate or measure the operating current of a 3-volt appliance first, assuming it is.

The voltage on the voltage divider resistor is 5-3=2V

Resistance = 2 ohms.

Three diodes in series, step down by 2 volts, depending on how much current you have, choose different current diodes. It's so simple that you don't need to draw any circuit diagrams. If you want high efficiency, use a switch to stabilize the IC.

It is OK to use a DC conversion regulator with an input of 5 volts and an output of 3 volts or a three-terminal regulator, but pay attention to the size of the output power and output current!

In the DC5V power supply positive series of 3 diodes, pay attention to the polarity, to ensure the forward conduction, because forward conduction, you can get. The current of the diode should be greater than the load current. ,

The LM1117 has a wide input voltage range, and the limit input voltage can be as high as 20V, so you have no problem with the input voltage of 6V.

Yes, it is a fixed output, not a fixed voltage drop.

For LM1117, as long as the input voltage UI meets the following requirements:

20>ui>(uo+
