If you take this power from a 12.5 VDC source, then the total amperage required increases to 3.31 Amps (or 3,310 mAH). We use 12.5 volts for 12 volt battery systems.ĭC Amperage - Now we know that our application uses 36 watts of total power. Therefore the 120 VAC x 0.3 Amps equals 36 Watts.ĭC Voltage - Output Voltage is rating of your battery system, usually a single 12 volt battery. It's calculated by multiplying voltage by amperage. Wattage - Wattage is the total amount of power the application uses. For instance, our example application draws 300 milliamps, which is the same as 0.3 Amps. If the transformer has a step up ratio of 4 to 1, the voltage across the secondary will be 40 volts and the current will be 1 amp. This number is usually rated in Amps, if the current is rated in milliamps (mAh) you can convert it to Amps by dividing the number by 1000. Two pole motor has the same mechanical frequency as the excitation voltage. The mechanical speed can be further reduced by using a motor with higher magnetic pole count. Most applications have this listed on the AC power brick. 60 Hz excitation voltage corresponds to 3600 RPM. For these examples, we'll use the US standard of 120 Volts AC (240 can be entered in the calculator for the inversion).ĪC Amperage - Input Amperage (AH) is how much current the application draws from the AC power. In the US it can be anywhere from 100-125 VAC. There is a solar article that goes well in depth on these calculations if you’re interested in the techie type stuff: Solar Info: The Down Low on Everything Up High Enter AC Device Ratings AC Voltageįind Your Battery Choose Your Inverter WalkthroughĪC Voltage - Many applications will have a range of Input AC Voltage. This calculator includes the typical inefficiencies in efforts to give you realistic DC Amperage Rating. Just enter your AC Voltage and AC Amperage into the fields below and we will do all the hard calculations for you. The calculator also provides the wattage rating you are pulling so you can properly size the power inverter you need! Per the power formula, voltage is equal to the power delivered to a device divided by the current that flows through it: V(V) P(W) ÷ I(A) The voltage V is equal to the power P in watts. This calculator helps you determine the DC amperage as it passes through a power inverter. To convert amps to volts, we can use the power formula that allows us to derive the equation for calculating the voltage. The first step to sizing the battery pack when using a DC to AC Power Inverter is to know your DC Amp rating. (Not to be confused with a converter, which takes AC to a DC.) Welcome to our AC to DC Amperage conversion calculator! So, you’ve got an electrical household device you need to run but no regular grid power available, right? For this you need a DC to AC Power Inverter that takes the DC voltage a battery provides and inverts it to AC voltage so that you can run an AC Powered Device.
