How a UPS Works

An explanation of how Uninterruptible Power supplies operate with animated block diagrams. Explains the differences between Transient Voltage and Surge Suppressors (TVSS), Automatic Voltage Regulators (AVR), Standby UPS's, Line-interactive UPS's and Online (Dual Conversion) UPS's. This video also provides a summary of the features of the most common types.

I came here to learn about UPS systems and had to watch the video a few times because of my lack of understanding in this type of technology. I was interested in reading the questions to get more understanding; however, I seem to be the only person that could hear-and I am hearing impaired. I appreciate the time this man (who is likely a husband, father, and grandfather that deserves respect) has taken to give us this information. It is worth focusing on the information--For those of you that have complaints about the audio, consider donating your money to hire a voice to redo this video. It is a shame that too many people feel that they must be entertained while becoming educated.

Your voice as other wrote is awfuly recorded, but overall very informational and exactly what i was looking for, thank you!

A simplified explanation and more than THANKS

I work for UPS and this is not how we work

[nishchiram]

Amazing visual presentation, Sir can you please tell me wat software u have used? it will be very helpful

[nsylbn]

Thanks a lot man i really was searching a lot for these video for my final project

[boyetlugay]

its an interesting topic but the voicing is hard to hear, pls speak louder and clearer. ty

Came here to better myself for power, ended up falling asleep at work

I have a question. Is all UPS compatible for all electronic device? I have an UPS but hesitate to use it for my guitar amp. hope for your reply, thanks!

This video contradicts infromation from other videos in how and when the battery is utilised during online operation. Infromation from elsewhere suggests that load is always directly powered by the battery with microcontroller regulating when battery is charged, disconnected and discharged. However, this video suggests that the load is always powered directly by the conditioning circuitry with the battery only kicking in on mains failure. Grateful if someone could pleas clarify which of the two scenarios is correct. I have a Riello Sentinel Pro and need to know if my UPS, during online operation, feeds load from battery always or whether it is fed from conditionaing circuitry, therefore when mains is available, battery is never utilised. Thanks.

Hi thanks for this video. A few days ago I had an unused UPS which I turned it into an Inverter. The project was successfully and it works fine. But I have a problem. The mentioned Inverter automatically turns off after exactly five minutes.There is a way to keep such inverter on for a long period of time? Any help please from your end. Thanks in advance.

"PLEASE HELP" I have an "Eaton 5E1100iusb" line interactive ups 660w. I am trying to save on power consumption and was wondering if the ups load is relative to the power consumption it uses from the wall outlet. EG: If the ups is powering a 400w pc is it's power consumption from the wall lower that when it's powering a 600w pc??? Thanx for the help

Thanks for this tutoriel . Please can you show us all circuits in réal ups electronic board .

Can you please tell me if a battery backup (with surge protection) can be used to CHARGE a small laptop (Microsoft Surface 5)?

[IqbalHamid]

Also, I am sure the surge/spike prortection is supposed to be upstream (ie: at oppositte end, at the start) and not downstream as shown. It makes not senes for it to be there.

Does inverter work during normal operation, or it stars working only after 'blackout' ? My question is - is on output normal sine current on normal work and than inverter current on alarm, or inverter always powers output .

sir do you know differenec between UPS and constant voltage transformer..plz send it

I have a Everest seriesUPS system with stabilizer, 800 VA. I only have two things plugged into it my PS4 system and a Panasonic 50" screen TV. I plugged the UPS into the socket around a day before to charge. Now when I plug everything in it will run for a time then beep at me and shut off. It seems like the TV and PS4 are running completely off the battery system and not from the house power supply. Could anyone tell me why this is?

I undestood nothing. You need to clear your voice and speak clearly.
