  • What is the difference between the 8/20us waveform and the 10/350us waveform in surge protective devices (SPD)

    What is the difference between the 8/20us waveform and the 10/350us waveform in surge protective devices (SPD)

    Oct , 08 2023
    The surge protector has an important parameter, 8/20us or 10/350us, which many people are unaware of. The main function of the surge protector is to respond to lightning strikes, including direct and induced lightning. The forms of direct lightning and inductive lightning have different energies, and their current waveforms are similar to 10/350us (direct lightning) and 8/20us (inductive lightning...

    What is single phase ups?

    Nov , 17 2023
    Single phase UPS has a single input and output source to the electrical equipment. With just one sinewave voltage, it only requires two wires to complete the circuit, one conductor and one neutral. Single phase UPS uninterruptible power supplies typically cover requirements up to 30 kVA. They are for servers, telecoms or computer systems, and network switches. Also they are along with any device t...

  • What is the ups power factor?

    What is the ups power factor?

    Nov , 17 2023
    Power factor (pf) is the difference between actual energy consumed and the apparent powerin an AC circuit. It will calculate as a decimal or percentage between 0-1 pf and 0-100% i.e. 0.9 pF = 90%. UPS input power factor The UPS input power factor is the ratio of UPS input active power to input power. UPS is not only a part of power supply, but also a load on the utility power source. It means the ...
