Yes, you can use a 300mA power supply in place of a 400mA supply, but it may not provide enough current for the device to operate properly. If the device requires 400mA and only receives 300mA, it may underperform, malfunction, or even be damaged due to insufficient power. It's important to ensure that the power supply meets or exceeds the current requirements of the device for safe and effective operation.
400mA refers to the amount of current the light consumes when it is operating. It stands for 400 milliamperes, which is a unit of electrical current. Knowing the current consumption can help you select the appropriate power supply for the light.
i am not sure, BUT according to the answer in this post:Can_you_use_a_9V_600mA_adapter_on_a_9V_400ma_scanneryou need an adaptor of 9v and AT LEAST 500mA (assuming that the appliance draws 500mA)
Using a 12V 500mA power supply instead of a 12V 300mA power supply will likely be fine as long as the voltage matches, but the higher current capacity (500mA) means the power supply can deliver more current if needed by the device. The device will only draw the current it needs, so having a higher current capacity power supply should not cause any issues.
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.
No, a power adapter must supply the same voltage, same polarity, and at least as much current as the load requires. Your adapter can only supply 300mA, which is less than the 700mA required by the load.Your game probably will not turn on and the power adapter may be damaged.
Answer You need the Voltage and the amps it can supply then use the magic triangle formula that is Watt = Amps X Volts say 400mA 12 volt that will work out to .4X12 = 4.8 watt
No because they have different connectors.
The voltage would match but the amount of power would likely not be enough to run the device. Under-power will not likely harm the device, but it won't work correctly. Always use the correct voltage/power for your devices!
No. The voltage rating is the same, but the lower current rating on the 400ma power supply might cause the voltage to drop way below 12 volts, and on some devices a lower voltage than it is rated for will cause it damage.
No, the adapter's power output has to be equal to or greater that the current draw of the device.
Generally, yes. If your devise will only draw 80mA, it will do it whether it is connected to a supply that is capable of supplying 300mA or 800mA. The amperage rating on the power supply is the highest current that it is rated for. It will easily and safely provide less current. The load that is connected to the power supply will determine the actual amount of current.
First, there are no DC transformers, transformers work on AC. If you have an AC/DC wall converter that has an output of 7.2 v DC, and a max current load of 400mA, then you can use this to power a DC motor that requires less than (7.2 x .4 = ) 2.88 watts of energy.
