Quick Answer: Can I use a transformer with higher amps?

Is it OK to use a power supply with higher amps?

4 Answers. The amperage rating on your power supply simply means that the supply can put out up to 2 amps, so as long as the voltage matches (12 volts) you could safely use a higher amp power supply for your device.

What happens if amperage is too high?

As long as the correct voltage is used, a device will draw only the amperage it needs, meaning there will not be “too many amps”. If an incorrect voltage is used — say a higher voltage than the device is rated to accept — then yes, too many amps may be drawn and the device can be damaged.

Do transformers affect amperage?

So when a transformer increases voltage, it decreases current. Likewise, if it decreases voltage, it increases current.

Can I use a larger transformer?

You can always use a transformer with a larger VA rating than the load requires. This means that the required operating voltage is 120 Volts, with a current of 2.4 Amps. Thus, the load is found to be 288 VA, so a 300 VA transformer (SD-43) should be used.

Can I use 500ma instead of 100mA?

For example, putting a 500mA pedal on a 100mA power tap would cause it to act erratically and probably shut down — it might even damage the pedal. Conversely, sending more milliamps than needed to a pedal is fine. Putting a pedal that draws 20mA on that same 100mA tap is no problem.

Can I use 500ma instead of 300ma?

As long as the voltage output is correct for your unit it is okay.

Does higher amps mean more power?

What are Amps? The strength of a current – how fast it flows – is measured in amperes or amps. Thinking back to the battery as a water pipe, the current would be the flow rate of the water. Higher amps mean that electricity is flowing more quickly and delivering more power to your device.

Is it better to have higher volts or higher amps?

A higher voltage system is more efficient than a lower voltage since it experiences less energy loss from resistance given the same amount of power draw. … You get the same exact voltage—but with 80 amps of current. That’s 80% more energy!

Can I use a 12V power supply on a 9V?

You can’t use a 12V adapter to power a 9V guitar pedal. A pedal that only handles 9V can be destroyed by using a 12V adapter. It’s possible for a power supply to ruin your pedal even if you get the voltage right.

What limits current in a transformer?

What is transformer impedance? Impedance is the current limiting characteristic of a transformer and is expressed in percentage. It is used for determining the interrupting capacity of a circuit breaker or fuse employed to protect the primary of a transformer.

Does using a transformer use more electricity?

It turns out that these transformers consume power whenever they are plugged into the wall, whether they are connected to a device or not. They also waste power when powering a device. … The power consumption is not large — on the order of 1 to 5 watts per transformer. But it does add up.
