    The difference between the first, second, and third levels of distribution boxes

    Jun , 22 2024
    What do the primary, secondary, and tertiary boxes of a distribution box mean? This is a relative issue. Let's make a hypothesis: a newly built residential area introduces a 10kV incoming line and builds a distribution room. The outgoing line from the low-voltage end of the transformer is 0.4kV to the distribution cabinet (primary distribution cabinet), then the outgoing line is led to the distrib...

    Differences in communication serial ports

    Jun , 22 2024
    RS-232 and RS-485 are two common serial communication standards, with the following main differences between them: Different transmission methods: RS-232 adopts a single end transmission method, and its data signal is relative to the signal ground, usually used for point-to-point communication; RS-485 adopts differential transmission mode, allowing multiple transceivers to be connected on the bus,...

    What is an active power filter Active Power Filter (APF) is a new type of power electronic device used to dynamically suppress harmonics and compensate reactive power, which can compensate for harmonics and reactive power changes in magnitude and frequency. The reason why the active filter is called active, as the name suggests, the device needs to provide a power supply (to compensate for the har...

    What are the characteristics of industrial UPS power supplies

    Jun , 14 2024
    Industrial UPS power supply needs to focus on the design of the ability to operate in high-temperature environments. Component design must be adapted to the operating requirements of industrial environments, high temperature and high humidity, but also to cope with corrosive gases on the corrosion of the system. Operating continuously at full load under a variety of operating conditions, industria...

    Methods for reducing ripple voltage

    Jun , 06 2024
    Brief introduction Ripple voltage is a voltage fluctuation in the output of a DC power supply, referring to the AC component of the output voltage. Excessive ripple voltage can have an impact on the normal operation of electronic devices, so reducing ripple voltage is an important issue that needs to be addressed in the power supply design process. This article will introduce some commonly used me...

    1. At the beginning of the bullying load is small, and expansion may occur at a later stage. There must be a redundant design that does not allow the load to be turned off during expansion. 2、It can be used in conjunction with the original generator as a power source or distribution for faulty configurations to ensure the smooth operation of power supply. 3, When a UPS failure, the faulty UPS batt...

    Indispensable components of using UPS uninterruptible power supply

    May , 25 2024
    A UPS uninterruptible power supply is a system device that connects a battery to a mainframe and converts DC power to city power through the modular circuitry of the mainframe inverter. High-efficiency double-conversion UPS with multiple modes of operation purifies power over the rated voltage and frequency range of IT equipment and industrial equipment. In choosing a modular system design, the UP...
