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.
