  • The structure and related advantages of the thyristor rectifier of the charger

    The structure and related advantages of the thyristor rectifier of the charger

    Mar , 28 2022
    Silicon controlled rectifier is a power control appliance based on thyristor (power electronic power device) and with intelligent digital control circuit as the core. It has many advantages such as high efficiency, no mechanical noise and wear, fast response speed, small size and light weight. The characteristics of the silicon controlled rectifier: it is "triggered". However, if a reverse voltage...

    Power Regulation Solution

    Mar , 28 2022
    Due to the influence of various factors such as power supply facilities and regional conditions, the voltage fluctuation of the AC power supply grid in some countries is still relatively large. Specially in some remote and rural areas of countries with unstable urban networks. The main conditions of AC power grid voltage fluctuation are as follows: (1) The voltage fluctuates high and low, and cann...

    Battery charging tutorial-Part 1

    Apr , 18 2022
    Current battery charging technology relies on microprocessors (computer chips) to recharge; using 3 stages (or 2 or 4 stages) regulated charging. These are the "smart chargers", and quality units generally are not found in discount stores. The three stages or steps in lead/acid battery charging are bulk, absorption, and float. Qualification or equalization is sometimes considered another stage. A ...

    UPS For Lift Application

    May , 30 2022
    Have you ever considered how you would evacuate people from a multistory building in case of power failure? Do you have responsibility for people coming and going from public buildings? If you do, you need to consider how you’re going to handle evacuation in the event of an extended power failure and are not equipped with a standby generator. It doesn’t need to be a dramatic situation just an exte...

  • What types of monitoring and recording devices are suited for high rate charging?

    What types of monitoring and recording devices are suited for high rate charging?

    Jun , 20 2022
    The higher the charging rate, the more critical it is to monitor the charging process to prevent permanent capacity loss. In efforts to preserve battery life, Fast and Opportunity charging incorporates a method of monitoring battery electrolyte temperature and/or internal resistance and adjusting charging current as necessary. Although these monitoring devices can have a very positive impact on ba...

    Effect of input capacitors between UPS and Generator

    Jul , 18 2022
    Input capacitors used for filtering purpose cause pure apparent power to flow between the supply and the UPS. Such power is referred to as leading or capacitive power. Gensets can manage limited amount of pure leading power, as it interferes with the excitation circuit in the AC generator, leading to voltage oscillations and genset’s shutdown. Safe operating area charts show the allowed gensets’ l...

    What are the soft costs of datacenter?

    Jul , 22 2022
    Data centers can’t afford to go dark. That’s why reliable critical power systems arecentral to their operation. Selecting and maintaining these systems comes at a price, but astronger understanding of “hard” and “soft” costs -- and what can be done to mitigate thelatter -- can protect the bottom line. Hard and soft costs vary from one operation to the next. In general, hard costs refer to the expe...

    How to lower the soft cost of Data center

    Aug , 01 2022
    Outages are a major fear for data centers. And for a good reason. Unfortunately, many companies still roll the dice by purchasing critical power systems,assigning someone internally to keep tabs on the equipment, and simply hoping the system comes through when it needs to. (Spoiler: it often doesn’t.) Scarce resources, a lack of skilled personnel, and increased edge computing (and the scattered fa...
