Can I use a 3 amp instead of 2 amp?

3 Amp should be okay. The main purpose of the fuse is to prevent burning wires. Radio Shack has the fuse in a higher voltage rating, but it won’t cause a problem.

Can I use 3 amp fuse instead of 5 amp?

A 3A fuse is supposed to break the circuit for any current higher than 3 Amps. So replacing the fuse by a 5 A wire will allow more current than the rated value through the system and might damage appliances or trigger a higher protection scheme to act promoting larger blackout.

What uses a 3 amp fuse?

Plugs for appliances rated up to about 700 watts should have a 3-amp fuse (coloured red). For example: 3A Fuse – Table lamp, standard lamp, television, video, computer, mixer, blender, fridge, freezer, power drill, jig saw, soldering iron.

Can I use 1000ma instead of 300mA?

Re: OK to use a 300ma adaptor with 1000ma Roland device? Matt Mayfield wrote: You can do this if you want to melt the adapter and potentially start a fire.

Can you use different power adapter?

As long as the voltage is the same on the adapter and on the device (also, I have 9V DC and 9V AC adapters, do not mix these up) and be sure the current required is less than the amount that the adapter can source otherwise you risk overloading the power supply.

Can I use a 12V 3A power adapter on 12V devices?

Yes, you can use a 12V 3A power adapter on 12V 1.5A device. You can also use a 12V 0.5A power adapter but the charging time will be three times longer. If you are a cautious person then you should use a manufacturer recommended power adapter.

How many devices can I hook up with a 3 amp adapter?

Since 1.5 is less than 3 and 12 = 12 then you should be OK. Adapter because your load device has a resistance rating that draws 1.5 amps. That means in theory that 3 – 1.5 = 1.5 which means that 2 devices actually rated at 1.5 amps from a 3 amp power adapter can be hooked up.

How many amps can a 12 volt power supply produce?

The output of the supply is 12 volts, and it can give 2 amperes of current continuously. It can’t give more than around 2.1 amps (maximum, I mean I am not even sure it can go up to 2.1 amps. The best case is around a teeny tiny more than 2 amps cause they have protection IC’s). That’s around 24 watts of power, (no supply is perfect).

Why do I need a power converter for a piano?

The converter is required to change the wall power from AC to DC so that it can be used by the piano. As for which type, it depends on the piano, but there are 3 main things to match up: Electronic devices run on either AC (alternating current) or DC (direct current) power.
