What is the rated power？

　　Rated power refers to the power of electrical appliances when they work normally. Its value is the rated voltage of the appliance multiplied by the rated current. If the actual power of the electrical appliance is greater than the rated power, the electrical appliance may be damaged; If the actual power is less than the rated power, the electrical appliance may not run.

　　In DC circuit, the product of rated voltage and rated current is the rated power of electrical appliances. Note: p amount =U amount ×I amount

　　Output power of power equipment or input power of energy-consuming equipment under normal operating conditions. Often in "kilowatts". It also refers to the power that the machines produced in the factory can reach when they work normally. That is, the power of a machine. The rated power of the machine is certain, P=Fv, so the force generated by the machine is inversely proportional to the running speed. For example, when a car is driving on a flat asphalt pavement, the traction force F required is smaller, and the speed can be higher; When the road is uneven or uphill, you need a lot of traction, so you must switch to low speed.

Rated power of computer

　　Rated power is the maximum power that the computer radiation eliminator can provide when it works continuously, and the unit is watt (W), or the unit is kilowatt (KW), and 1kW = 1000W. The computer radiation eliminator is used to replace the computer power cord when working, so its rated power must meet the needs of the computer and is the most important parameter of the computer radiation eliminator. Rated power is closely related to rated voltage and working current, which is equal to rated voltage multiplied by working current in principle, so the rated power of computer radiation eliminator is generally between 1000W and 2000W W. Like the working current, the rated power is the maximum power that can be provided in continuous normal work, not that such power is necessary in work. In fact, the power of the computer radiation eliminator at work is far less than this value, which basically depends on the power required by the computer itself, and the power consumed by the computer radiation eliminator itself is very small.

Rated power of power supply

　　Rated power refers to the power that the power supply stably outputs for a long time when the ambient temperature is -5 degrees to 50 degrees and the voltage range is 180 V to 264 V. When testing the power of power supply, manufacturers usually do it at about 50 degrees. The specific method of marking the rated power of the power supply is generally as follows: under the premise of not exceeding the maximum current output by this circuit, gradually reduce its load resistance, and measure its load voltage drop and ripple coefficient at the same time. When the load voltage drop and ripple coefficient exceed the allowable range, record the current value at this time as the maximum working current. Record the maximum working current of each output, and then compare it with the power standard formulated by Intel, so as to determine the rated output power of the power supply. Rated power is the most important standard in power supply. Usually, the power of the power supply generally refers to the rated output power of the power supply. On the nameplate of the power supply, the marked power should be rated power.
