If a power saw is 12volts will a 400 watt inverter be sufficient?

No. The 12volts will not make a difference. The inverter converts the 12volts to 110/115volts. A 400watt inverter is not sufficient to run a power saw or any heavy power equipment like that. Laptops consume 20-50watts, while a coffee pot would consume more like 200-400watts. Your power equipment is a much heavier load, between 1000-4000watts depending on if it is a power saw or something larger. A basic 7 1/4 circular saw will use anywhere from 1000-2500 watts on starting and will draw a constant 800-1500 watts. Keep in mind it will draw more as you put it under load of cutting something, this will not run on a 400 watt inverter, let alone an 800 or 1000watt. You could however possibly run a power drill on that inverter, but otherwise no luck.


How many amps equals 400 watts?

Watts = Amps x Volts x Power Factor. Power Factor = 1 for resistive loads and gets smaller for inductive loads like motors. Assuming home voltage of 120 Volts and a PF = 1 your answer is 400/120 = 3.33 amps.


Can 400volts heater element get supply from 230 volts?

Yes you can run a 400 volt heater on 230 volts but you will not get the full wattage rating that the heater produces at 400 volts.


How can you calculate the capacity in megawatts of a 400 kv power line?

You have to know the current carring capacity of the line and the power factor to make the calculation. Watts = Amps x Volts x p.f If p.f is unity, then watt = Amps x Volts

How many watts equals one AMP at 400 volts?

This question cannot be answered without knowing the voltage. Watts=Volts x Amps In the United States mains voltage (what you get in your house) is 120 Volts, so 120 x 400 = 48,000 Watts In Europe mains voltage is 230 Volts, so 230 x 400 = 92,000 Watts


How many watts is alpine v12 mrv-f505 amplifier?

The Alpine v12 MRV-F505 amplifier puts out up to 200 watts of RMS power at 4 Ohms and using 12 volts. At 14 volts, it puts out up to 400 watts of RMS power with a bridged 4 Ohms ratio.
