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. 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. Most applications have this listed on the AC power brick. 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. Browse our collection.įind Your Battery Choose Your Inverter WalkthroughĪC Voltage - Many applications will have a range of Input AC Voltage. We offer an extensive selection of top-grade DC to AC converters - and unlike some of our competitors, we stock all major brands in our state-of-the-art 14,000-square-foot facility. Converters are popular in RVs and boats, where you plug into AC shore power to charge a battery pack while at the same time running a DC load, such as your water pump, fan, or other accessories. For those trying to run a load with or without batteries, they will need a charger converter/power-supply. A battery charger takes the AC voltage and converts it to DC and chargers a battery or battery pack. If you want to convert AC-to-DC, then you would need a charger or a charger converter/power supply. In a DC-to-AC inverter, the energy only flows one way. ![]() Can all DC to AC Inverters convert AC to DC if used in reverse? What inverters convert DC to AC the best?īattery Stuff offers a large selection of exceptional DC to AC converters, including highly rated pure sine wave power inverters, which help to prevent short circuits, overloads, and overheating. Do I need a DC to AC Inverterįor homes or businesses that are off-grid and are powered via solar power, or you need to use an appliance that requires AC power but is not connected to the electric grid (e.g., you rely on batteries or power banks), you will need a DC to AC inverter. In DC, the electric current flows solely in one direction, whereas in AC the power changes direction. What are the differences between DC and AC? Inverters consist of switches, transistors, and other components to regulate the flow of the current. How to convert DC to AC?ĭC to AC conversion involves using a device called an inverter to convert DC voltage to AC voltage. It’s the most common form of electrical power used for creating and distributing electricity to supply houses and businesses. ![]() The electrical current in AC power works by periodically changing direction in a circuit at regular intervals. Once at the device, the DC power is used and will then continue through the device and complete the circuit. Note: This calculator includes the typical inefficiencies to give you a realistic DC amperage rating.įAQs about DC and AC Conversions How does DC work?ĭC power flows is unidirectional, meaning electrons only flow in one direction through the wire to the device it is powering. Just enter your AC voltage and AC amperage into the fields below and we will do all the hard calculations for you. Our calculator will help you determine the DC amperage as it passes through a power inverter and provides the wattage rating you are pulling so you can properly size the power inverter you need. The first step to sizing a battery pack when using a DC to AC power inverter is to know your DC amp rating. Read on to learn how to convert AC to DC with our voltage-to-amperage calculator. 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. Our AC amps to DC amps conversion calculator can help you convert electric currents from an alternating current (AC) to a direct current (DC). Keep in mind that this should not be confused with a converter, which takes AC to DC. ![]() If you have an electrical household device that you need to run but have no regular grid power available, you’ve come to the right place.
