  • The characteristics and application points of multi-output switching power supply

    The characteristics and application points of multi-output switching power supply

    Features of multi-output switching power supply     1. Generally, only one output voltage is regulated, and the other voltages are unregulated.     2. The voltage of the unregulated output will change with the load of its own way (load adjustment rate), and will also be affected by the size of ot...

  • What is a multi-output LED switching power supply?

    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...

  • How do you decide to use a surge protector and why do you choose it?

    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...

  • The principle of switching power supply.

    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...

  • How to choose the correct switching power supply

    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...
