Sure. It is just a DC to AC power inverter. Just Google DC AC Inverter or Power Inverter. The most common variety is 12 VDC to 120 VAC because of automobiles. You'll have to match your power requirements with various models. 120 VDC doesn't seem to be a common supply voltage.

You can change from one voltage to another using a appropriate converter. For AC, you need a transformer. For DC, you need a DC-DC converter, which are complex little devices. There is no fixed values to change from one voltage to another. You can change from any voltage to any voltage with the right hardware and circuit design. Keep in mind, the more esoteric the change, the more expensive it will become as you drift from off-the-shelf solutions. 200V is an odd voltage. US Residential service has 240VAC for large appliances. That may be what you are looking for. There are many entries on this site about how to add a 240VAC outlet.

What is the formula to convert amperes from 440V to 460V?

For the same power - Watts - you need to run twice as many amps at 220V than at 440V. For the same load, it'll pull half the amps at 220V than it did on 440V

Can you run your neon sign of 120v 50hz 60hz 0.6a 7.5kv 30mA in an Australian 240v power outlet?

No. The neon sign is fed by a step-up transformer. Primary side 120V, secondary side 7500V. If you applied 240 to the primary side you would get 15000 volts on the neon tube. A flash over and then nothing. If you can find a transformer from 120V to 240V or 240V to 120V then you are good to go. Connect 240V to 240V side and you will get 120V out the other, connect the 120V side to the neon sign and you should have light. Transformer should be at least 100va. This will give you an output of .83 amps at 120V


Can a 2-pole circuit breaker be used for 110V 220V or 440V?

All three, on 110V a split receptacle, on 220V a baseboard heater, on 440V a construction heater or similar resistive load.


How do you ctmm motor protection relay setting?

Just calculate from motorplate: Watts/(Square3*V*cosP)=> example motorplate says: 4.7Kw 440V cosP: 0.82 4700W/(square3*440V*0.82) here you get minimum setting for motor, this case 7.5A JT


What happen to 440v motor running at 480v?

Depends on the motor. If it is a synchronous motor it will run too fast.


What does it mean if we are getting 440 volts in our houses?
