      The Principle and Application Range of Shanterups Power Supply

      Backup power supply, also known as Off-Line UPS, is only a "backup" UPS. Direct power supply to power equipment also charges batteries (Normal Mode). Once the quality of power supply is unstable or power failure, the circuit of city power will be automatically cut off, and the direct current of batteries will be converted to AC hand-on power supply (Battery Mode) until the city power is restored. Normally, "UPS will only intervene in power supply when power is cut off in the city", but the AC power converted from DC is square wave, which is limited to supply capacitive loads, such as computers and monitors.



      Online Shante UPS power supply system: Its single output power is from 0.7 to 1500 kVA. For this type of machine, when users adopt the multi-machine "redundancy" configuration scheme, 6-9 Shante UPS power supply with the same power output and the same model can be directly combined to form a large Shante UPS power supply system of 7000-8000 kVA. For on-line output Shante UPS power supply, the AC power supply provided to users is a high quality sinusoidal power supply. Interactive Shante UPS power supply: Its single output power is about 0.7-20 kVA. For this Shante UPS power supply, when the municipal power supply is in the range of about 150-264V, it provides users with a general municipal power supply which is regulated by a ferroresonance regulator or by a transformer tap (which means that the factors such as frequency fluctuation from the general municipal power grid, high waveform distortion caused by "harmonic pollution" and series connection from the power grid still exist, which is actually practical. Actual AC power supply for households. For this kind of Shante UPS power supply, only when the voltage of municipal power supply is lower than 150V or higher than 264V, it is possible to provide users with real "Shante UPS power supply inverter high quality sinusoidal wave" power supply. Therefore, some manufacturers often call it "quasi-online Shante UPS power supply" or "three-port Shante UPS power supply". When the city power supply is normal, the converter of Shante UPS power supply, which has two functions of inverter and charger, assumes the function of battery charger.



      Delta converter type Shante UPS power supply: its single output power is from 10 to 480 kVA. For this kind of Shante UPS power supply, when the local voltage changes within (+15%), the power supply it provides to users is an AC regulated power supply formed by the superposition of more than 85% of the common municipal power supply and the inverters generated by Delta inverters. When the local voltage exceeds (+15%), the main inverters of Shante UPS power supply provide users with real "high quality sinusoidal power supply of Shante UPS power supply inverters" under the condition of battery discharge.



      Backup (Offline) sine wave output Shante UPS power supply: its single output power from 0.25 to 2 kVA. For this kind of Shante UPS power supply, when the voltage of Shante UPS power supply is in the range of 170-264V, it provides users with the general municipal power supply which has been regulated by transformer taps. Only when the voltage of Shante UPS power supply is lower than 170V or higher than 264V, can it provide users with real "Shante UPS power supply inverter" of high quality sinusoidal power supply. Backup Square Wave Output Shante UPS Power Supply: Its single output power is from 0.25 to 1 kVA. For this kind of Shante UPS power supply, when the local voltage is about 165-270V, it provides users with the general municipal power supply which has been processed by tap voltage regulation of transformer. When the voltage of municipal power supply is lower than 165V or higher than 270V, it provides 50 Hz square wave power supply with stable output characteristic to users. For backup square-wave output Shante UPS power supply, when the power supply of municipal power supply is abnormal, because the AC power supply it provides to users is square-wave power supply, not sinusoidal power supply, under these conditions, users are not allowed to use inductance load (e.g. fans, fluorescent lamps, etc.). Otherwise, either the inverters of Shante UPS power supply itself are burnt down, or the load of users is damaged.



      According to the technical performance of experts, the order should be: online Shante UPS power supply, Delta converter Shante UPS power supply, quasi-online Shante UPS power supply, backup sine wave output Shante UPS power supply, backup square wave output Shante UPS power supply. In terms of price, the order is just the opposite. According to the market sales in recent years, the backup sine wave
