This equation can provide a good starting point for practical applications.Ĭonverting AC to DC voltage is quite simple mathematically and provides a basis for understanding the necessary conversions to successfully power DC devices from a standard AC supply from the power distribution grid. Remember, of course, that in a real-life application, you’ll need to account for losses due to inefficiency in the conversion. Converter charger changes AC shore power to DC power to run 12V loads and charge your lithium RV batteries at the campground. With this information, we can convert the AC supply from the power grid to the appropriate voltage to power the device. The converter uses the 110-volt AC power from the local power source and transforms it into the 12-volt DC these items require. Progressive Dynamics 9100 Inteli-Power Lithium Converter - 12V - 30A - PD9130LV. This equation also allows us to work backward from the device, knowing its DC power requirement, to calculate the necessary input AC. As a theoretical example, an incandescent light bulb will grow equally brightly on 141V AC (peak voltage) and 100V DC, since we express the RMS of 141V peak as: We can use the RMS equation above to determine and allow the conversion of AC to power DC devices. Unfortunately, only hypothetical conversions maintain 100 percent efficiency. It is important to note that this determines the theoretical DC voltage equivalent based on the peak AC voltage, not the exact DC voltage that will result from any real-life conversion. Divide the peak voltage by the square root of two to obtain the RMS voltage, which is equivalent to the required DC voltage. If we know the peak voltage of an AC, we can quickly figure out the necessary DC voltage. Pyle Universal Compact Bench Power Supply - 30 Amp Regulated Home Lab Benchtop AC-to-DC Converter w/ 13.8 Volt DC 115/230V AC Switchable, Screw Type Terminals, Cooling Fan - Pyle PSV300. RMS for a standard AC waveform is equal to the peak voltage divided by the square root of two, as shown in this RMS to DC formula: This is possible since we presume the wave to be identical each period. In the case of typical sinusoidal AC waveforms, the RMS over all time is equal to the RMS of one period of the wave. Output power: 30A continuous, 400W Output voltage: 13.6/14.2V DC (switchable) Input voltage: 108-132V AC AC power cord: Integrated Warranty: 2 years Weight: 2300g Dimensions (LxWxD. RMS stands for root mean square and refers to the square root of the average (arithmetic mean) of the squares of all values in the set. The DLS-30 provides 400 watts at 30 amps, and is great for use with a high power charger, or for charging lead-acid batteries directly Specifications. In general, we express DC voltage as AC RMS voltage. As a power supply, the units tightly controlled regulation allows the user to operate a nominal 12VDC load up to 30 amps. Fortunately, working out the mathematical conversion is quite simple. The IOTA 12 Volt DLS-30 Power Converter/Battery Charger from IOTA Engineering converts nominal 108-132 AC voltage to 13.4 DC voltage for both DC load operation and 12V battery charging. Physically converting alternating current (AC) power to direct current (DC) power involves several steps and a device called a rectifier.
