Dimplex DDF250B 250 W Heater, Black/silver

Product Information

Hello Rabih, basically the 550W units can produce more than 550W of electricity per hour if it’s a very sunny day. That’s a fellow engineer advised the use of a 5 kW inverter, instead of a 3.3 kW inverter. If you would be producing 3,300W, that would be exactly 15 amps on a 220V circuit. Now, if it is very sunny and you actually are getting 5,000W, the amps increase to almost 23 amps.

Hello Sandra, do both run on 120V? If they run on 220-240V, the amps are halved. Additionally, the fridge might draw 11.6 amps when running at 100%. Most fridges run on much a lower percentage and hence draw much fewer amps. If your 10 amp circuit can handle that, you’re fine. Reply Hello Jerald, you only need to operate with the basic electric power equation: P = I*V (or Watts = Amps*Volts). Let’s say you have a 220V voltage and want to get 10,000 Watts. Here how you calculate this: 10,000W / 220V = 45.5 A. Basically, you need a current of 45.5A on 220V voltage to be able to generate 10,000W. 12V voltage and 80A current will only generate 960W; this is less than 10% of what you are hoping to get. Hope this helps. Reply Namely, the Brightown heaters if a 400-watt heater that draws only 3.6 amps at 110V or 3.3 amps at 120V amps. That means that even if you have a 30 amp 120V RV generator, you will still have 26.7 amps left if you run the Brightown heater at 100% heating output.

When you figure out amps, you will probably need adequate wiring for your amp size. You can consult the ampacity AWG chart with wire sizes in mm, mm2, and amps here. I have a automobile alternator output project. I am hoping to take a 220 v motor and tie it in with my alternator to produce upto 10K watts. But I really am starting to feed stupid tring to understanding the conversion from 12v system to my idea. What the hell am I missing? If I can get upto 80a out of my 12v system in my auto, what would I have to do to get my needed result. Thank you for your time! Reply

V is electrical potential or voltage, measured in Volts (V). The standard voltage for most electrical devices is 110-120V, and upgraded voltage powerful electric devices use 220V or 240V. Batteries run at 12V or 24V. Browse through our top selections to find the perfect heater for your needs.

Hello Chris, 182 kW is a huge wattage. You can use the electric power equation to easily see how many amps would be sufficient. Here’s the calculation: Question, I am buying a plasma cutter one plugs into 120 outlet and the other into a 220 outlet.other wise they are the same, they both draw 45 amps no more no less. Would the output be the same or would the 45 amps in the 220 be more. Thanks ruben Reply For 25 Amps, for example, you would already need an amp breaker. But if you plug such a device into 220 V, the current generated is only 13.64 Amps (there is no need for amp breakers).
