Can 48V voltage be used normally for 300W electrical equipment?

As long as the capacity of the battery is enough, yes, and what is your load?

Don't know if the resistor wire is too thick and will have a large loss?

Answer: Power = square of voltage resistance.

And what does it mean to have a load, how can there be a load if there is no deficit?

Answer: light bulbs, electric furnace wires, computers, televisions, refrigerators are loads, batteries are power supplies, the power supply voltage of light bulbs and electric furnace wires is reduced, the power will be reduced, and the voltage of computers and televisions will not work after the voltage drops beyond the range it allows.

Which one is more cost-effective to remodel yourself or buy an inverter?

If it is an electrical appliance that generates heat, you can design and make it yourself. Suppose you are using a 48 volt power supply with a power of 300 watts, and the resistance of the heating wire is: r = 48 * 48 300 ohms, and the current through the heating wire:

i=300 amps, the resistance wire is much thicker than the 220V voltage.

The 48V battery needs to know its capacity to give you an idea, if the battery capacity is too small, the 300W electrical appliance is not usable, and the unit of battery capacity is MAH

As long as the capacity is enough for 1000W, it is fine.

1. The rated voltage of the electrical appliance is 12V, and the rated current is 1A.

2. The output voltage of the power supply is 12V, and the output power is 300WIf.

Then: the power of electrical appliances p=ui=12*1=12w is less than the output power of the power supply, which is completely usable and can be used with confidence.

If the voltage is suitable, you can use it, 300W is just the load capacity of the power supply, and the actual amount of W is determined by the electrical appliance.

Yes, it won't burn out. It's just too wasteful, 300W power supply to 12W load.

The power provided by the telecommunications bureau is extremely limited, not only can not carry the inverter, but even the small load is not enough. Up to a few light-emitting tubes can be lit.

**The line is a high-impedance circuit, the voltage and current are very small, and the load cannot be driven, and the light-emitting diode is estimated to burn.

You're right, you can use it directly, you have to distinguish between positive and negative poles.

Ha ha!!! This brother is kind of interesting. The voltage is basically rated.

300w is the power. Electric bikes 24V also have 300W, and electric motorcycles 48V also have 300-500W. Three-phase 380V AC motors are also available in 300W.

The two-phase capacitor 220V motor also has a 300W one. But you can't mess with it. When the voltage changes, the current changes.

When the current increases, it generates heat. If the fever is severe, smoke will soon come out. Even**.

In addition, there is a difference between AC and DC. I won't go into detail here.

It is rated voltage, and you can see the nameplate.

Electric machinery (commonly known as "motor") refers to an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. In the circuit it is indicated by the letter M (D in the old standard).

Its main function is to generate driving torque, as a power source for electrical appliances or various machinery. Generators are denoted by the letter G in the circuit. Its main role is to utilize electrical energy to convert into mechanical energy.

The nameplate description is as much as it is. You can't pick it up casually.

No. Because the 380V phase line and the neutral line are 220V', the original 220V lighting and equipment are in normal use.

Household appliances are generally 22ov! You can't use three-phase electricity! The route must be re-routed!

According to the 300W power, the current, as long as the power supply voltage at the terminal reaches 220V, the square millimeter copper wire can be used. If the cost of using the square is large, it costs 80 yuan for 100 meters and 160 yuan for 100 meters.

The civilian voltage is remembered to be +-7%. Capped at 237. The effect of long-term high voltage on household appliances is that they are prone to overheating during operation, and can cause overvoltage damage to equipment containing electronic components.

248V If the measuring instrument is accurate, then it is on the high side, which has an impact on the service life of electrical appliances.

It doesn't matter, as long as the Chinese household appliances do not exceed 250V, there will be no problem.
