Classification of Santak UPS power supply
1.. According to the main structure of the circuit.
(1) backup Santak UPS power supply. The working process: when the power supply is abnormal, the reserve UPS switches to the state supplied by the battery through the switch, and the inverter enters the working state. At this time, the output waveform is AC sine wave or square wave. It
(2) online Santak UPS power. The double variant mode is usually adopted. When the power supply is normal, the on-line UPS inputs AC voltage and charges the battery continuously. At the same time, AC/DC converts AC voltage into DC voltage. By pulse width modulation technology, the inverter converts DC voltage into AC sinusoidal voltage to supply the load, thus playing the role of stepless voltage stabilization. When the electricity is interrupted, the reserve battery starts to work, and the stored energy is converted into AC sine wave or square wave to supply the load through the inverter. Whether in the normal or interrupt period of power supply, the inverter is always in working state, which fundamentally eliminates the impact of voltage fluctuation and interference from the grid on the load, and realizes load non-interference, voltage stabilization, frequency stabilization and zero conversion time. It
(3) dual inverter voltage compensation online Santak UPS power supply. When the power supply is normal, the two inverters only adjust and compensate the difference between input voltage and output voltage. The maximum power of the inverter is only 20% of the output power, so the power intensity is small and the power margin is large, which enhances the output capacity and overload capacity of the UPS. The output active power can be equal to the calibration value without restricting the load current peak coefficient and load power factor. To talk about
(4) online interactive Santak UPS power. The inverter of online interactive UPS is always in working state with bidirectional function. When the power supply is normal, the inverter is in the reverse state and charges the battery group; when the power supply is abnormal, the inverter turns into the inverter state and converts the DC voltage of the battery group to the AC sine wave output. The online interactive UPS conversion time is shorter than the backup UPS, and the protection function is strong. To talk about
2. classification by reserve time.
(1) standard Santak UPS power supply. A UPS equipped with a built-in battery pack is called a standard machine. Due to the limitation of volume and weight, it is only limited to medium and small power. To talk about
(2) UPS, which needs external battery pack, is called long acting machine. Its capacity ranges from 100 volt amperes to tens of kilo volt amperes. To talk about
3. classification by input / output mode.
According to input/output mode, it can be divided into single-phase input/single-phase output UPS, three-phase input/single-phase output UPS and three-phase input/three-phase output UPS. It
Single-phase input/single-phase output mode is adopted in _low-power UPS, and three-phase input/three-phase output mode is used in medium and high-power UPS. When the three phase power supply is used, the power distribution and load distribution are relatively easy. Each phase carries part of the load current. To talk about
4. classification according to output waveform.
UPS can be divided into sine wave and square wave. The UPS with square wave output is not suitable for inductive load, because the inductive load will cause the square wave to produce transient sharp wave, destroying UPS and load equipment. The output waveform of most backup UPS is square wave. To talk about
5. classification by output capacity.
__can be divided into micro UPS (less than or equal to 1kV A); small UPS (greater than 1kV A, less than or equal to 5kV A); medium UPS (greater than 5kV A, less than or equal to 30kV A) and large UPS (greater than 30kV A, less than or equal to 100kV A).
