This toy just sits on the desk, so it’s a good candidate to modify to accept a DC power supply instead of batteries. This idea is not well suited to something like an R.C. Car, but in a pinch, you can use it on the remote control for your TV. Wall outlet power is generally alternating current, or ‘AC’.
Batteries are direct current ‘DC’ and only push the current in one direction. An AC to DC power supply can change AC wall power to DC power. Many common devices that have batteries (laptops, smart phones, etc) only accept DC power. They use a AC to DC power supply to allow us to charge the device by plugging it into the wall.
If I replace my batteries with a power supply of equal voltage, then the current in the system also stays the same. This project uses this relationship to replace Voltage, V supplied by a battery with voltage supplied by a DC power supply – nothing else is changed.
Say half an hour, then 24 V 24+ A supply. Replacing a battery from a battery-operated equipment with a power supply can be tricky. Especially when the equipment uses an electric motor. The problem is that an electric motor can draw very large startup current - it can be as 10-20 times the nominal for a couple of seconds.
A DC Power Supply is needed that allows for adjustable voltage and current. Any such as that shown on the right will suffice to provide the voltage and current that we need in order to recharge a battery cell.
A battery is able to supply that current, while a typical power supply with overcurrent protecton may latch or enter hiccup mode, from which it cant escape. First of all you need to determine the nominal motor current and the maximum current. The maximum current flows when the motor is mechanically overloaded.

Lenink AC Power Supply Adapter for AAA Battery,Replace 3 AAA Battery,Black . Visit the Lenink Store. 4.7 4.7 out of 5 stars 859 ratings | Search this page . 500+ bought in past month. …
Yes, a battery charger can be used as a power supply, but be cautious. It …
No, a DC power supply cannot always replace a battery. The power supply must match the battery''s voltage and current output to meet device requirements. Safety is also …
In series they can supply about at most 50mA current continuous. So any reasonable power supply will handle that. If you want to power it off of a 12V supply then what …
A power supply converts AC to DC voltage to power devices, while a battery charger does the same but with the added capability to replenish a battery''s charge. Understanding the nuances between them is essential for …
Welcome to The Power Supply Shop. We specialise in providing quality power supplies, along with the most convenient way to order the exact power adapter for your device. The power …
However, in general you can simply replace a 9V battery with a regulated 9V DC (!) supply. DC …
Then, you need to cut the wire lead and connect it to a DC power supply that matches the voltage and polarity of the device. Finally, you need to plug the DC plug into the …
However, in general you can simply replace a 9V battery with a regulated 9V DC (!) supply. DC is important. The power supply should have an "equals"-sign printed on it after …
DC batteries can be charged using a DC power supply. When choosing a battery, it is important to check the required current of your device and ensure that the …
With a typical adjustable DC power supply, I can set the current (typically a mode called I-Set) to provide a fixed current by controlling the voltage. (within the limits of the …
Batteries are direct current ''DC'' and only push the current in one direction. An AC to DC power supply can change AC wall power to DC power. Many common devices that have batteries (laptops, smart phones, etc) only accept DC …
The 5V power supply was too large. When I hooked up a 3V power supply, the LED string functioned properly with the correct amount of light output/brightness. I realized that I didn''t have to worry about the current rating …
How can I take a 9V battery plus a snap adapter and create a power supply that would be equivalent to the DC power adapter? Do I need to add a 6 Ohm resistor in the loop …
A power supply converts AC to DC voltage to power devices, while a battery charger does the same but with the added capability to replenish a battery''s charge. …
You can easily recharge batteries if you have a DC power supply. All that is needed to recharge battery cells is DC current. With DC current, electrons will flow back into the battery, …
I have a PCB which is nominally powered by a custom battery pack. Specifically, this battery pack: So five cells connected in series, at 3.6V each, which I assume means that the nominal output …
You really need a ±3 V supply. Or, you can get two 3 V supplies and connect the + of one to the - of the other. That common connection will be the ground of your circuit.
Batteries have a very "quiet" supply voltage; there is no mains hum or switching spikes as you would find in a lot of DC converters so be prepared to be disappointed should you use one. …
Batteries are direct current ''DC'' and only push the current in one direction. An AC to DC power supply can change AC wall power to DC power. Many common devices that have batteries …
If you are tired of replacing batteries in your portable radio or in any other battery-powered device, using an AC power adapter is a good alternative. All you need to do …
How can I take a 9V battery plus a snap adapter and create a power supply that would be equivalent to the DC power adapter? Do I need to add a 6 Ohm resistor in the loop to ensure that I = V/R or is that too simple?
No, a DC power supply cannot always replace a battery. The power supply …
Now I know, that one AA battery is 1.5 volts and hence I need a 6 volt adapter to replace all four. But there are either 1 ampere or 2 amperes adapters on the market and I can''t …
Replacing a battery from a battery-operated equipment with a power supply can be tricky. Especially when the equipment uses an electric motor. The problem is that an electric motor …
Yes, a battery charger can be used as a power supply, but be cautious. It converts AC to DC and provides specific current and voltage. However, without a battery, the …
