    Lithium battery capacity loss cause analysis

    Jun , 21 2023
    Lithium-ion batteries are the fastest-developing secondary batteries after cadmium-nickel and nickel-hydrogen batteries. Its high-energy properties make its future look bright. However, lithium-ion batteries are not perfect, and their biggest problem is the stability of their charge-discharge cycle. This paper summarizes and analyzes the possible causes of capacity attenuation of Li-ion batteries,...

    What is a Rack UPS

    Jul , 03 2023
    IT Racks Have Unique Power Requirements A rack uninterruptible power supply (UPS) system is designed for use within standard 19-inch IT racks or rack-based enclosures. Rack-based UPS systems must be designed to provide maximum power in compact packages with built-in batteries. A rack UPS generally uses from 1U to 12U of vertical rack space. Most rack UPS systems employ either online (double conver...

    Industrial UPS with Ride-through Protection

    Jul , 28 2023
    Introduction Electrical utilities use reclosers on medium voltage supply to isolate faults caused by events such as lightning strikes, tree branches across lines, or animals making contact with live wires. The result of a recloser operation is a momentary power outage, lasting for up to a few seconds. These outages can cause an unplanned production stoppage which can be very costly. When momentary...

    The Role of AC Capacitors in High Speed Circuits

    Aug , 18 2023
    1、Introduction For low-frequency circuits, resistors and capacitors can be analyzed as ideal devices. However, in high-frequency circuits, these two devices will not be "ideal". Today, our main discussion is about the issue of AC capacitors, which are commonly known as AC coupling capacitors. Their main function is to filter out the DC component of the signal, which is symmetrical about the X-axis...

    What are the characteristics of industrial UPS power supply

    Aug , 29 2023
    Industrial UPS power supplies need to focus on the ability to operate in high-temperature environments. The design of components must adapt to the operational requirements of the industrial environment, adapt to high temperature and humidity, and also be able to cope with the corrosion of corrosive gases on the system. Under various operating conditions and continuous full load operation, industri...

    Why only online UPS topology provides mission critical load protection

    Sep , 09 2023
    Why does only online UPS topology provides mission critical load protection? Modern, static UPS systems are broadly classified into three design architectures: on-line, off-line and line interactive. This post describes and compares the three types and explains why – for truly critical loads – online ups topology is the only acceptable approach. Facility executives today face increased demands for...
