What is the rated power

Rated power refers to the power of the normal operation of the appliance. Its value is the rated voltage of the electrical appliance multiplied by the rated current. If the actual power of the appliance is greater than the rated power, the electrical appliance may be damaged, and if the actual power is less than the rated power, the electrical appliance may not run.

In a DC circuit, the product of the rated voltage and the rated current is the rated power of the electrical appliance. Recorded as: P =u amount XI Amount

The output power of power equipment or the input power of an energy-consuming device under normal operating conditions. Often in units of "kw". It also refers to the power that a factory-produced machine can achieve when it is working properly. The power of a machine, as is commonly said. The rated power of the machine is certain and P=FV, so the force produced by the machine is inversely proportional to the speed of operation. For example, when a car travels on a flat tarmac, it needs less traction F, a larger speed, and when the road is uneven or uphill, the traction required is high and must be used at low speeds.

Rated power of the computer

The rated power is the maximum power that can be supplied by the computer's radiation-eliminating device, in Watts (w), or kw (kw), 1-kilowatt = 1000 watts. Computer radiation elimination device to replace the computer power cord, so its rated power must meet the needs of the computer is the computer radiation elimination of the most important parameters. Rated power and rated voltage, operating current has a very close relationship, in principle equal to the rated voltage times the operating current, so the computer radiation elimination device rated power generally between 1000W to 2000W. As with the working current, the rated power is the maximum power that can be provided in a continuous normal operation, and not necessarily the power that is required to work. In fact, the computer radiation elimination device in the work of the power is far less than this value, basically depends on the computer itself needs the power, the computer radiation to eliminate the consumption of their own energy is very small.

Rated power of power supply

Rated power refers to the ambient temperature of 5 degrees to 50 degrees, voltage range 180v~264v, the power supply for a long time stable output power. Manufacturers in the test power supply, generally in the environment of about 50 degrees. The specific method for identifying the power supply's rated power is generally as follows: without exceeding the maximum current of the output, the load resistance is gradually reduced, the load pressure drop and ripple coefficient are measured, and the current value is recorded as the maximum operating current when the load pressure drop and ripple coefficient exceed the allowable range. Record the maximum operating current of each output, then compare it with Intel's power standard to determine the rated output power of the power supply. The rated power is one of the most important standards in the power supply. Generally, the power supply power generally refers to the power supply rated output power. On the nameplate of the power supply, the power of the marking should be rated power.
