Emmanuel I have a 12v car battery and I also have v electric motor. So can the 12v battery run the electric motor??? Depending if the motor is an AC or DC motor you would need either inverter or converter to run the motor off of a battery.
I have a car audio amplifier and subwoofer set up that i can no longer use in my vehicle. It is a watt amp when connected to a 1 ohm load. The subs play real low, like down to 25hz. Which makes me want to bring this inside for movies.
Stupid idea, I know. However, I am still interested in repurposing this setup. The question I am asking is beyond my comprehension, so please be patient. If the amp pulls around amps DC to create watts at 1 ohm. How does that equate to AC? The standard breaker in my house is 15 amp's, with a few at Is there a power invertor that can plug into a volt outlet and provide the power needed for the amp?
Would it require a volt? Would that still not be enough power? Any help will be appreciated. If you need more information, please let me know.
Be warned the cooling fan at that rating is likely to be loud. You could place a car audio capacitor inline between the inverter and the amp just like you would on a vehicle. Most of these can run off of a 15 amp breaker, with the exception of the 75 amp needing a 20 amp, and the 90 or amp needing a 30 amp breaker.
In most setups you would need a deep cycle battery meant to act as a buffer for the larger amp draws the power-supply isn't capable of outputting. Given you are no longer going to have a large amp alternator working as a power-supply you will most likely need an larger battery pack to act as a buffer. I would suggest giving our tech line a call for further information, but a lot of this may be trial an error till you come up with the right system.
In the end the music being played can greatly affect your power requirements, so what works for one person may not work for another. Adam Penny Love it. Gives me a better understanding when using AC appS. TECH You are correct when it comes to the amp draw a 24v inverter will pull half the amps then a 12v inverter. You are also correct you won't see any loss if you use the same amount of batteries in your 12v setup as you would in the 24v setup. The biggest difference is when your AH remains the same Take for instance a 12v AH battery bank and a 24v AH battery bank.
In this case the you might think the 24v bank would last only double the time, but it actually last a little longer than double. The more amps you pull out of a battery bank the less AH capacity that battery bank is, which is why most batteries have several different AH ratings based off the Amp draw the battery is subjected to. In this case a 12v AH battery pack could withstand a 10 amp draw and last only 10hrs, but the 24v AH battery bank lasts 21hr 41 min.
In this scenario you get an additional 1hr 41min of run time due to the less amps being drawn out of the higher voltage battery pack. Randy Edward Marshall I have a small camper that I only use electricity for a few led lights and a small tv with a total load of about 75 watts at v I have a small w inverter about how long will a amp hour battery last before it would need to be recharged? If you inputted VAC at 0. At that time you would need to recharge the battery to prevent excess discharge.
In most situation like yours we typically see people using a much larger battery pack if they are wanting to run a TV. Obviously, this load only accounted the 75 watts, so with all of the other accessories you could easily be excessively discharging the battery each night depending on how much you are using the TV and other accessories.
Rick Nicholson This calculator is almost spot on, it would be best if you could choose either to list amps or watts. Remember you're making this calculator for newbies, so yes I know you can divide watts by north america and get the amps, but for newbies, easier if you can enter either. John It is hot in Houston. I have a Btu air conditioning with a power consumption of watts and a nominal current of 2. What wattage inverter do I need? And how long do you think a car battery will last using the above setup?
You would be lucky if a car battery could take that draw for even an hour before excessively discharging the battery. As far as what inverter to purchase… You need to account for your surge draw which you state is The inverter you select must be able to handle that draw, and you might want to talk to the manufacturer to see how long that surge lasts. Most inverters come with a surge rating for less than a second, so if your surge last longer it generally forces you into a larger inverter.
BatteryStuff Tech If your device runs off 48 volts then there is no need to be looking for an inverter. Your device is meant to run off either a 48v power-supply , or a 48v battery pack.
Steve Southen i have a watt invertor fitted to my nissan patrol ute. BatteryStuff Tech As you can see by the calculator that would draw about Amps an hour out of a 12v battery pack! Next I would suggest using our Calculator Sizing a 12 Volt Battery to a Load , as it depends on how long you want to run that load for…. Warren This tool was helpful. Just a quick question. I guilt a solar generator with a watt panel, a 12V inverter that puts out VAC and a 12 V battery.
It is supposed to run a stock well that is Amps. With just one battery it only runs 3 minutes the overloads the battery. If I read the calculator right this pump will draw So if I connect 3 12 V batteries in parallel, will that be sufficient to run this pump or should I connect 4 12 V Batteries?
BatteryStuff Tech Now that you used this calculator to determine what you will be drawing out of the battery.
This calculator will tell you what size battery pack you need to create depending on how long you want to run the well for. Jason Can I use this in reverse? BatteryStuff Tech In reverse it would be a charger vs an inverter, however if the charger runs off VAC and draws a A then it will put out approximately A on a 48V system, but it might vary depending on the efficiency of the charger.
Ron I have a portable BTU air conditioner unit. The tag shows that it uses watts and 4. It runs very well with a watt generator.
How long can it run using an inverter, a amp hour AGM battery rated at watts? This would pull BatteryStuff Tech Glad to help! I will send your recommendation up the food chain and see if we can make it happen! BatteryStuff Tech Either the multi-meter is hooked up backwards, or you have forced the batteries to charge backwards.
Usually you are reading the reverse terminals. Najm hi, why do we hav some devices taking negative voltage? Bill Mertz Good morning. I have calculated that I need Amps DC per day. How many watt 12 volt solar panels do I need to keep up with this demand. My battery bank is Ahs 12 volts. Regards Bill. Thank you ALL for the info. BatteryStuff Tech That depends on the efficiency of the converter. On the 48 volt side, you are using essentially watts.
The wattage on the other side, the 24v side, will depend on the efficiency of the conversion process. Jonathan Burns Hi tbere i am looking to no how long my appliances will last for with 2 batteries working of a watt inverter drawing watts in total a total of 88 odd amps of dc how long will my batteries last and what size of solar panel would suit to maintain my batteries as i have only a splitt relay wired as a charging system.
The same calculations will work. John i wish to power a series of appliances whose total sum of wattage is watts for a minimum of 3 hrs non stop. Also , what specification of solar panel charging system can charge the battery in a very short time like 2 hours of sunlight…we do have intense sunlight in my region. It will not work for your situation.

Ups Calculator Pc
In electronics , a Schmitt trigger is a comparator circuit with hysteresis implemented by applying positive feedback to the noninverting input of a comparator or differential amplifier. It is an active circuit which converts an analog input signal to a digital output signal. The circuit is named a trigger because the output retains its value until the input changes sufficiently to trigger a change. In the non-inverting configuration, when the input is higher than a chosen threshold, the output is high. When the input is below a different lower chosen threshold the output is low, and when the input is between the two levels the output retains its value. This dual threshold action is called hysteresis and implies that the Schmitt trigger possesses memory and can act as a bistable multivibrator latch or flip-flop. There is a close relation between the two kinds of circuits: a Schmitt trigger can be converted into a latch and a latch can be converted into a Schmitt trigger. Schmitt trigger devices are typically used in signal conditioning applications to remove noise from signals used in digital circuits, particularly mechanical contact bounce in switches.
Calculator | DC to AC Amperage Conversion Run Through an Inverter
Since the calculations yield approximate values, an appropriate safety factor should be considered when designing and specifying system components, such as wire size and length. Note — if this amps is drawn from the battery for one hour, amp hours AH of battery power will be used. To support amp hours of battery power, amp hours of battery capacity is required. Note — if this 75 amps is drawn from the battery for one hour, 75 amp hours AH of battery power will be used.
The inverter with operational amplifier
Documented in this article is a common question relating to the inverter current draw and a breakdown of expectant voltage and efficiencies. How much current is drawn from the 12V or 24V battery when running a battery inverter? The simple answer is- divide the load watts by 10 For a load of Watts, the current drawn from the battery would be:. So a W inverter with a Watt load would be 50 25 Amps, not 75 Amps. The same inverter with a Watt load would draw 60 Amps.

Summing Amplifier
The calculator solves the summing amplifier resistors based on the input and output voltage range requirements. It is a great tool to design a bipolar to unipolar converter, as an example and other circuits. Enter the input range, Vin1 to Vin2, the output range, Vout1 to Vout2 and a reference voltage Vref which helps in adjusting the common-mode level of the amplifier. Since the 2-input summing amplifier has 4 resistors, you need to choose two resistors, R1 and R3, and calculate R2 and R4.

In this tutorial, we will learn about Summing Amplifier, its configurations, types of summing amplifiers inverting and non-inverting and a few applications of Summing Amplifier. One of the important applications of an Operational Amplifier is the Summing Amplifier otherwise known as Adder. As the name suggests, a Summing Amplifier is an Op-amp based circuit where multiple input signals of different voltages are added. For information on the basics of Op-amp, read Operational Amplifier Basics. Many applications in electronic circuits require two or more analog signals to be added or combined into a single signal. One of best examples for such requirement is the Music Recording and Broadcasting applications.
The long-tailed-pair phase inverter with negative feedback was used by Leo Fender in the 5F6-A Bassman and subsequently became an overwhelming favorite for classic large amp designs, Marshalls in particular. The basic long-tailed-pair without negative feedback is shown in the schematic. As the input signal voltage increases, the plate current through the left tube increases, causing the inverted output voltage to decrease because of the increased voltage drop across the plate resistor RL1.
