  • The way the thyristor rectifies

    The way the thyristor rectifies

    Aug , 07 2024
    A Thyristor rectifier is a power electronic device that is widely used in the conversion process from alternating current to direct current. It achieves a unidirectional flow of current by controlling the turn-on and cut-off of the thyristor, which converts alternating current into direct current. Thyristor rectifiers are characterized by high efficiency, reliability and fast response. How thyrist...

  • How to extend the power supply time of uninterruptible power supply (UPS)

    How to extend the power supply time of uninterruptible power supply (UPS)

    Aug , 03 2024
    There are two ways to extend the duration of an uninterruptible power supply： 1. Increase battery capacity. According to the length of time required to increase the number of batteries, but this method will cause a relative increase in battery charging time, but also increase the number of corresponding maintenance equipment, increase product size, resulting in an increase in the overall cost of U...

  • Wiring Method of Transformer

    Wiring Method of Transformer

    Jul , 26 2024
    1.Wiring Method Of Transformer： There are two types of common transformer windings, namely "triangle wiring" and "star wiring"; In the connection group of the transformer, "D" is represented by a triangle, "Yn" is a star with a neutral wire, Y is a star, and n is a neutral wire.  The combination of the two windings of the transformer forms four types of wiring groups: "Y,y,"D,y", "Y,d" and "D...

  • Working principle of inverter

    Working principle of inverter

    Jul , 26 2024
    Input interface section: There are three signals in the input section: 12V DC input VIN, working enable voltage ENB, and panel current control signal DIM. VIN is provided by the Adapter, and ENB voltage is provided by the MCU on the motherboard, with a value of 0 or 3V. When ENB=0, the inverter does not work, while when ENB=3V, the inverter is in normal working condition; The DIM voltage is provid...

  • Voltage drop calculation formula

    Voltage drop calculation formula

    Jul , 19 2024
    Voltage drop is a common issue in circuits. To calculate the decrease in voltage, we can use the following formula: Vout=Virn * (R2/(R1+R2)). This formula is based on the principle of resistance voltage division, where Vin represents the input voltage, Vout represents the output voltage, R1 represents the resistance value of the upper resistor, and R2 represents the resistance value of the lower r...

    The role of voltage transmitters

    Jul , 19 2024
    A voltage transmitter is a device used to convert an analog electrical signal generated by a sensor into a standard voltage or current signal output. It is widely used in the field of industrial automation and process control, and is also used to measure and monitor environmental parameters such as temperature, pressure, liquid level, etc. 1. What is a voltage transmitter Voltage Transmitter, abbr...

  • What is the meaning of float charging for intelligent three‐stage charger in battery charger?

    What is the meaning of float charging for intelligent three‐stage charger in battery charger?

    Jul , 12 2024
    Float charging: Keep constant voltage charging, the charging current continues to decrease, and the battery is charged with maintenance type. When the charging current decreases to the set value or the charging time reaches the set value, the red light of sufficiency will be on, and the time will be about 2H, charging 10% of the power. Ordinary chargers are old‐fashioned chargers, charging, whethe...

  • What are the meanings of deep discharge and excessive discharge of UPS batteries

    What are the meanings of deep discharge and excessive discharge of UPS batteries

    Jul , 11 2024
    Deep discharge generally refers to the discharge of approximately 80% of  the rated capacity of a battery. After a period of use, there will inevitably be some active substances sinking in the power UPS power battery. If the active  substances are not activated in a timely manner, it will inevitably have some  impact on the capacity of the battery. Therefore, it is best to cond...

    Explanation of terms related to UPS power supply

    Jul , 06 2024
    Transient Recovery Time: The time it takes for the output voltage to return to the specified range when there is a sudden change in load (0‐100%, 100%‐0), usually on the order of seconds (ms). Filter: a device used to eliminate noise, the input or output filtered to obtain a pure contention of the alternating current. Shielding: The use of physical principles, used to isolate the electromagnetic r...
