What is a multi-output LED switching power supply?
The multi-output switching power supply means that the general input AC power is rectified and filtered and converted into DC power and then converted into high-frequency AC power to be supplied to the transformer for transformation, so that one or more sets of voltages are generated. The main...Read more -
How do you decide to use a surge protector and why do you choose it？
1. Basis of judgment: basically all electrical equipment should be lightning protection, and electrical appliances with pure power access (such as home lighting, air conditioning, refrigerator, etc.) are relatively less likely to be damaged by lightning, while those with power and signal acce...Read more -
The principle of switching power supply.
Switching power supplies are based on high-frequency switching technology to convert unstable and cluttered alternating current (AC) into a low direct current (DC) voltage required by other devices. In fact, the switching power supply can be said to be an auxiliary cardiovascular device for o...Read more -
How to choose the correct switching power supply
1. Choose the appropriate input voltage range.Take AC input as an example, the commonly used input voltage specifications are 110V, 220V, so there are corresponding 110V, 220V AC switching, as well as the general input voltage (AC: 85V-264V) three specifications.The input voltage specificatio...Read more -
How much do you know about pure sine wave inverters？
Inverter OUTPUT function: after opening the “IVT SWITCH” of the front panel, the inverter will convert the direct current energy of the battery into pure sinusoidal alternating current, which is OUTPUT by the “AC OUTPUT” of the back panel. Automatic voltage stabili...Read more -
About PFC regulated switching power supply
Among PFC switching power supplies, the switching power supply regulated power supply is a very important part. The switching power supply function in the PFC is not much different from the ordinary switching power supply, but there is a difference in power supply. Ordinary switching power su...Read more -
Classification of PFC functions
As far as we know, there are currently two types of PFC, one is passive PFC (also called passive PFC), and the other is called active power supply (also called active PFC). Passive PFC is generally divided into “inductance compensation type” and “valley-filling circuit ...Read more -
The function and principle of waterproof switching power supply
Waterproof switching power supplies are increasingly used in public lighting applications. In specific applications, this type of new waterproof switching power supplies not only have the advantages of constant current power drivers and cold light lighting fixtures, but also have a very hig...Read more -
The DC switching power supply
The function of the DC switching power supply is to convert the original ecological power supply (coarse power) with poor power quality, such as battery power, into a high-quality direct current (fine power) that meets the requirements of the equipment. The core of the DC switching power supp...Read more -
Flyback transformer switching power supply
Flyback transformer switching power supply means that when the primary coil of the transformer is excited by the DC pulse voltage, the secondary coil of the transformer does not provide power output to the load, but only after the excitation voltage of the primary coil of the transformer is ...Read more -
Application of AC-DC Switching Power Supply Chip in Switching Power Supply
Switching power supply is the use of electronic switch components such as transistors, field effect tube, silicon controlled rectifier thyratron, etc., through the control circuit, the electronic switch devices constantly “on” and “off”, make electronic switching devic...Read more -
Classification, composition and working principle of solar photovoltaic system
Solar photovoltaic systems are mainly divided into off-grid photovoltaic power generation systems and grid-connected photovoltaic power generation systems. 1. The off-grid photovoltaic power generation system is mainly composed of solar cell components, controllers, and batteries. If you wan...Read more
