1. Power cut protection---When flashy power cut change batteries direct current source into alternating current to continue by UPS instantly power supply.

2. Voltage of on any account is protected---Built-in manostat of the UPS when exorbitant or voltage of one town report is too low (AVR) will do proper adjustment,

Make the voltage of town report maintains in spendable limits, if too low or voltage is too excellent,pass but scope of application, UPS continues changeover of batteries direct current source into alternating current power supply, in order to protect user facilities.

3. Undee and lack fidelity processing---Be defeated by distribution circuitry to convey to be carried to the client as a result of electric power by, the use of all sorts of machine equipment, what often cause weaveform of town report voltage is lack fidelity, because weaveform is lack fidelity, generation harmonic violates facility and can make temperature of power system transformer elevatory, general requirement breaks sincere <5% , general UPS design breaks sincere <3% .

4. Frequency is stable---Cent of frequency of one town report is 50Hz/60Hz two kinds, alleged frequency is the cycle with each fluctuant second, 50Hz is every second 50 weeks second, the frequency of Taiwan town report is 60Hz, the mainland is 50Hz. What the abrupt change that uses n is carried to cause rotate speed when the dynamo runs by the client is fluctuant the drift of electric power frequency that will make changeover comes out is errant, the electric power that UPS changes can offer stable frequency.

5. Voltage is stable---Voltage of one town report suffers electric power easily to carry the influence of circuit character, from change the user tension with electric closer place makes an appointment with 130~120V higher, from change the user voltage with electric further place is inferior make an appointment with 100~90V, too tall or voltage is too low can make user facilities shrinks life, serious when equipment of meeting burn down, use online UPS can provide steady voltage power source, voltage is fluctuant be less than 2V, can lengthen equipment life and protective equipment. Land please: ? of pole of uncut jade of Mian Lai white browses more information

6. Restrain horizontal model noise---Generation of noise of one horizontal model is between live wire and neuter line.

7. Restrain in all modular noise---Generation of altogether model noise is in live wire / between neuter line and ground wire.

8. Dash forward wave protection---General UPS can be added outfit dash forward wave absorb implement or point discharge design is absorbed dash forward wave, in order to protect user facilities.

9. Instantaneous answers protection---Tension can be created sometimes when town report suffers interference bulgy or cave in or instant are pressed fall use online UPS can offer stable voltage, make voltage does not change 2V, can lengthen equipment life and protective equipment.
