Q:s the UPS power supply only in the battery when the power outage or the mains voltage is below the input range?

This statement is not precise enough. When the mains input is normal, the UPS will be powered by the mains supply to the load, this time the UPS is an AC mains regulator, and it also charge the battery to the machine; when the electricity interruption (accident power failure) , The UPS immediately to the battery DC power, through the inverter zero switching method to continue to supply 220V AC load, so that the load to maintain normal work and protect the load soft, the hardware is not damaged. UPS is the abbreviation of "Uninterruptible Power System", which can ensure that the computer system will continue to work for a period of time after the power outage so that the user can save the file so that the user will not cause the power outage Affect work or loss of data.

Q:A few days before the thunder, my computer power and network card hack, and the amplifier connected to the regulator, nothing. Do not know if there is a voltage regulator UPS function? In the thunder, voltage, current suddenly too large, will not automatically regulator?

Now the general UPS has a regulator Sand's TG series did not, there are other cheap machines without General price has, 175V to 275V Better is 145V to 300V

Q:What is the difference between the inverter and the UPS?

The inverter is a single inverter function, and the UPS is a charge-discharge filter rectified uninterruptible power supply, far worse.

Q:The load is a 150 (standby) ~ 350 (full load) of the desktop plus a 40W monitor, but would like to power after a long period of time, normal use (do not play the game, is to browse the web) the best over 1 hour, 2 hours better, I should probably choose what kind of UPS, which brand will be better? There is power when there is no noise, electricity and charging time must be quiet. The The White asked the great gods. The The Thank you.

General UPS configuration to the following formula: UPS power supply (VA) × delay time (hours) ÷ UPS power supply DC = required battery safety hours (AH) To Hills C3KS delay 2 hours as an example we have to calculate the following: Note: Mountain C3KS start DC: 96V 400 volts x 2 hours ÷ 96V = 8AH The result is the need for 8AH battery to meet the 2 hours of power supply, (because C3KS start DC is 96V- (UPS in the factory when the standard DC voltage) General battery mostly 12V DC, 96V (UPS start DC voltage) ÷ 12V (battery DC voltage) = 8 So, (with 8 10 batteries as a group) battery on the line.

Q:Server what ups power lines

Server, then it is recommended to buy online, power outage conversion time of 0 seconds. Home is generally a backup UPS, in the moment of power failure conversion time than the line slightly longer, and sometimes lead to restart, brand Well, APC, Sandton, Hills.

Q:15KVA UPS power supply with a large line switch

15KVA is generally three into a single and three into three out 80% of the following load can choose 63A / 3P open It is recommended to use 128A / 3P open on full load Open the choice of more commonly used Schneider, ABB's. In accordance with the requirements of the use of UPS input is not allowed to open with leakage protection, the output can be brought.

Q:Because the power failure, the company's financial department to buy two Hills 500i UPS Do you need to turn off the UPS after work? The Thank you Also after the power outage, the computer and other equipment is turned off, need to shut down the UPS?

UPS does not need to be closed every day. UPS uninterruptible power supply works as follows: AC-DC conversion: the grid to the AC power by the autotransformer step-down, full-wave rectifier, filter into a DC voltage, the inverter circuit. DC-AC inverter circuit: the use of high-power IGBT module full-bridge inverter circuit, with a large power margin, the output dynamic range of the output impedance is particularly small, with fast response characteristics. Due to the use of high-frequency modulation current limiting technology, and fast short-circuit protection technology, so that the inverter regardless of the supply voltage transient or load impact or short circuit, can be safe and reliable work.

Q:I would like to ask: UPS power supply life how long?

Allen's UPS power supply can generally be used for 5 to 10 years, depending on the UPS power supply storage environment is different, may be able to use longer.

Q:Such as the title, the best recommended a few more choice, thank you!

At present, UPS brand too much. The It is recommended to use the mountain of the bar. The To look for the trademark of Hill. about the price. 2000W load converted into VA words. The You can use 3KVA UPS. The Host price of about 2500 or so. Backup time takes 10 hours. Requires 16 100AH batteries. Each section about 950 yuan (Panasonic battery), plus 16 battery cabinet. Need about 1,000 yuan. About 18700. There are also a lot of cheap brand. The specific price to the computer city asked or find the UPS business bar

Q:UPS uninterruptible power supply is generally used in what place?

The specific backup time depends on the capacity of the battery pack and the power of the electrical equipment.
