Output power of power equipment or input power of energy-consuming equipment under normal operating conditions. Often in units of "kilowatts". It also refers to the power that can be achieved when the machines produced in the factory work normally. 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, so the time can be longer; When the road is uneven or uphill, you need a lot of traction, so you must switch to low speed.
Question 2: What does the rated power of power supply mean? Power supply can be divided into rated power, maximum power and peak power.
Rated power: The ambient temperature is between -5~50 degrees, the input voltage is between 180V~264V, and the power supply can output stably for a long time.
Maximum power: At room temperature, the input voltage is between 200 V and 40 V, and the power supply can stably output power for a long time. Generally, the maximum power is about 15% higher than rated power. For example, the rated power of Xingu Nuclear Power is 325PQ W, and the maximum power is 287W, which is close to 300 W.
Peak power: the maximum power that the power supply can achieve in a very short time, and the time can only be maintained between a few seconds and 30 seconds. The peak power is related to the use environment and conditions. It is not a definite value, but it can be very large, which is very easy to mislead users. For example, Xingu Nuclear Power 325PQ has a rated power of 250W and a peak power of 350W.
Obviously, only rated power and maximum power have practical significance.
Question 3: What does rated power mean? What does input power mean? Input power is the power consumed by electrical appliances.
Rated power generally refers to the effective power that electrical appliances can continuously output; That is, the maximum power that can work continuously under normal working environment.
Question 4: What does the rated power of air conditioner mean? Air conditioning is generally divided into cooling power and heating power. The so-called rated power is the power measured at nominal voltage and current.
Question 5: What does the rated input power mean? Input power is the power consumed by electrical appliances.
Rated power generally refers to the effective power that electrical appliances can continuously output; That is, the maximum power that can work continuously under normal working environment.
Question 6: What's the difference between maximum power and rated power? Rated power refers to the maximum power that the equipment can achieve under the condition of continuous operation and ensuring the specified indicators. Rated power represents the actual capacity of the equipment. The maximum power is the power that can be achieved in a short time under the premise of meeting the basic functions, regardless of whether other quality indicators of the equipment can be achieved. Generally, the ratio of maximum power to rated power is 1.5-2, which depends on the wealth left by the design and the type of equipment.
Question 7: What is the difference between rated power and peak power? When the music is played with pictures, the sound fluctuates, and sometimes it rings lightly. If a signal with constant loudness is sent to the speaker and gradually increases, the maximum power that the speaker can bear for a long time without being damaged is "rated power";
The concert rang for a while, and then it was light. If the sound is particularly loud at this moment, which greatly exceeds the "rated power", but the speaker is not damaged because of a very short time, then the maximum power that the instantaneous speaker can bear is called "peak power".
Question 8: What do you mean by rated power? Rated power: electric power at specified voltage.
The normal residential electricity consumption is changed to 220 V. Represents 220 volts of electric power. If the electric power of electrical appliances is 1kw, it will consume one degree of electricity in one hour.
Question 9: What does the rated power of 200W mean? Power supply can be divided into rated power, maximum power and peak power.
Rated power: The ambient temperature is between -5~50 degrees, the input voltage is between 180V~264V, and the power supply can output stably for a long time.
Maximum power: At room temperature, the input voltage is between 200 V and 240 V, and the power output of the power supply can be stable for a long time. Generally, the maximum power is about 15% higher than rated power. For example, the rated power of Xingu Nuclear Power is 325PQ W, and the maximum power is 287W, which is close to 300 W.
Peak power: the maximum power that the power supply can achieve in a very short time, and the time can only be maintained between a few seconds and 30 seconds. The peak power is related to the use environment and conditions. It is not a definite value, but it can be very large, which is very easy to mislead users. For example, Xingu Nuclear Power 325PQ has a rated power of 250W and a peak power of 350W.
Obviously, only rated power and maximum power have practical significance.
Question 10: What does the rated power of the speaker mean? Rated power is the work done by current per hour. As we say at home, one degree of electricity is 1000W of work per hour. It's not scary to say that the bigger the better, the more power it consumes.
