The output power of a power supply is UI.
The total power of a power supply is EI.The output power of a power supply is UI.The power of a power supply is categorized into: rated power, maximum power, peak power. Rated power: ambient temperature between -5~50 degrees, input voltage between 180V~264V, power supply can be a long time stable output power.
Maximum power: at room temperature, the input voltage is between 200V~240V, the power supply can be a long time stable output power, the maximum power is generally larger than the rated power about 15%. Peak power: power supply in a very short period of time can reach the maximum power, time can only be maintained between a few seconds to 30 seconds.
Introduction of power supply
Power supply is a device that converts other forms of energy into electrical energy. A generator converts mechanical energy into electrical energy, and a dry cell battery converts chemical energy into electrical energy. Generator, the battery itself is not charged, its two poles have positive and negative charges, respectively, from the positive and negative charges to generate voltage.
Load in the conductor would have been, to produce current only need to add voltage can be, when the battery poles connected to the conductor in order to produce current and the positive and negative charges released, when the charge is dissipated, but also when the charge is exhausted current (voltage) eliminated.
Power supply use: power supply products are widely used in industrial automation control, scientific research equipment, industrial control equipment, computers and computers, communication equipment, power equipment, instruments, medical equipment, semiconductor refrigeration and heating and other fields.
