How to calculate the required ups load capacity?

Oct , 19 2023

Measured in “watts”, UPS load capacity is an important factor to consider when choosing a UPS (uninterruptible power supply). It determines how many electronic devices the UPS system can support. This post will tell you how to choose the right UPS with required UPS load capacity in the following four steps. Clarify UPS Measurement Units UPS systems are rated either in kilowatts (kW) or in kilo-vol...

Inverter energy storage system on the role

Oct , 27 2023

First, the basic principle of inverter Inverter is a device that converts direct current to alternating current, its main principle is to use the switching characteristics of semiconductor devices (such as field effect tubes or thyristors, etc.) to control the power supply voltage and current through rapid switching, so as to achieve the conversion of direct current to the corresponding frequency ...

What are the characteristics of industrial UPS power supply

Oct , 28 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...

Method for providing the service life of valve-controlled closed lead acid Battery (VRLA)?

Nov , 03 2023

1 Temperature affects battery life: thermal runaway causes temperature rise: Valve-controlled closed lead-acid battery (VRLA) charging when the internal gas recombination itself is an exothermal reaction, so that the battery temperature rises, floating charge flow increases, the gas evolution increases, and the battery temperature rises higher, the battery itself is a "poor liquid", tightly assemb...

The working principle and control method of IGBT voltage modification method

Nov , 03 2023

Unlike the resistance method, the voltage method involves changing the driving voltage during the control phase to control voltage and current overshoot. There are approximately two methods to change the driving voltage. One is to achieve the change by dividing the driving voltage through a resistor, and the other is to change the output signal in the control chip (DSPFPGA), and then convert it in...

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?

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 ...
