1. Different meanings
A switching power supply, also known as a switching power supply, or switching converter, is a high-frequency electric energy conversion device is a kind of power supply. Its function is to convert a level of voltage into the voltage or current required by the user through different forms of architecture. The input of the switching power supply is mostly AC power (such as commercial power) or DC power, and the output is mostly equipment that requires DC power, such as personal computers, and the switching power supply converts the voltage and current between the two.
Portable UPS energy storage power supply, designed for outdoor emergency, with lightweight, high capacity, and high power. There are batteries, DC power circuits, and control circuits inside. When the mains power supply is interrupted, the control circuit of the UPS will detect and immediately start the DC power circuit to input 220V AC power so that the electrical appliances connected to the UPS will work For a period of time in order to avoid losses due to mains interruption. Switching power supply is to convert 220V alternating current into the required direct current. It can have multiple sets of direct current input, mainly rectification filter circuits and control circuits inside. Because of its high efficiency, small size, and complete maintenance, it is widely used in electronic equipment.
2, the principle is different
There are two types of modern switching power supplies: one is a direct current switching power supply (DC-DC), and the other is an alternating current switching power supply (AC-DC). The output of the switching power supply is generally DC, and the function focuses on the conversion of the power supply.
Portable UPS power input and output are AC-AC (including AC-DC, DC-DC, and DC-AC inside). The function focuses on maintaining the stability of the output power supply and, at the same time, ensuring that the power supply can continue to be uninterrupted when the input is abnormal.
3. Different uses
Switching power supply products are widely used in industrial automation control, special equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, Electrical equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, liquid crystal displays, LED lamps, communication equipment, audio-visual products, security monitoring, LED light strips, computer cases, digital products, and instruments, etc.
Portable UPS energy storage power supply scope: telecommunication network installation and maintenance optimization; military information company; geographic surveying and mapping team; absentee oil exploration team; architectural design survey; water conservancy and water affairs inspection; advertising media outdoor shooting; forestry It can also be used as a direct current or alternating current power source for agricultural and wild resources investigation, etc. It can be used for lighting and other loads, with a compact structure, easy to carry, and reliable use. It should be used in emergency rescue, emergency power supply, backup power supply, and other usage scenarios.
2. Characteristics of outdoor portable energy storage power source
