What is a Power Rating?
The rated power of machinery refers to the maximum output power that can be achieved by mechanical equipment. The actual output power of mechanical equipment will not be greater than the rated power , which is different from electrical appliances.
Rated power vehicle power supply
- For vehicle power supplies, the rated power generally refers to the effective power that can be continuously output; that is, the maximum power that can be continuously operated under normal working conditions. The rated power is one of the most important parameters of the vehicle power supply. The larger the rated power, the more equipment the power supply can load. The power of the vehicle power source generally comes from the battery in the car, so its rated power will not be too large, generally between 100W and 800W, but for appliances that generally consume less power such as mobile phones, laptops, handheld computers, Cameras are enough.
Rated power car speaker
- The rated power is the effective power that the car speaker can work continuously and stably, that is, the power that can withstand this value for a long time without being damaged. This is the power parameter that the car speaker has practical significance. Generally, when testing the rated power, a sine wave signal is input to the speaker within the rated frequency range. The signal duration is 1 hour. The speaker does not cause thermal damage and mechanical damage. In theory, the rated power of a car speaker does not mean that such a high-power car amplifier must be required to push it. The difficulty of driving a car speaker is mainly determined by its sensitivity and impedance characteristics.
Rated Power Computer
- The rated power is the maximum power that the computer radiation eliminator can provide when it is continuously working. The computer radiation eliminator is used to replace the computer power cord when it is working, so its rated power must meet the needs of the computer. It is the most important parameter of the computer radiation eliminator. The rated power is closely related to the rated voltage and working current. In principle, it is equal to the rated voltage multiplied by the working current. Therefore, the rated power of computer radiation eliminators is generally between 1000W and 2000W.
Rated power supply
- Rated power refers to the stable output power of the power supply for a long time when the ambient temperature is -5 to 50 degrees and the voltage range is 180V to 264V. Rated power is the most important criterion in power supply. Under normal circumstances, 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 the rated power.
Rated power amplifier
- For power amplifiers, rated power generally refers to the ability to continuously output
Rated power speaker
- For speakers, the rated power is generally referred to as the speaker can withstand this value of power for a long time without damage, which does not mean that such a high-power amplifier must be required to push it. To decide.
- According to international standards, there are two ways to label the power of speakers: rated power (RMS: sine wave root mean square) and instantaneous peak power (PMPO power). The former refers to the driving of an 8 speaker within the rated range. The continuous analog signal of the waveform is specified. After a certain interval and repeated a certain number of times, the maximum electrical power of the speaker does not cause any damage. .
