I was searching for a cheap UPS which can handle my computer system, I have searched Electroncis Market Saddar Karachi and found most of low quality poor performance UPS that can operate a computer costs around 7 to 12 thousand (4+4 UPS).
After viewing market situation I have decided to make a UPS by my own with following objectives
1. UPS will be cheap in cost.
2. Can Operate a Computer efficiently without restarting it.
3. There must be something different as compare to other available UPS in market.
4. Provide long backup so it can run on a small battery and can give longer backup.
5. Must be smaller in size and easy to handle.
With having all above mentioned objectives I have purchased a 4+4 Transformer from Adam Electronics (Co-Operative Market Saddar Karachi) along with MOSFET Transistors circuit and a IC based circuit which is specially designed for computers.
Total Cost of Project.
Body : 350/=
Body Parts and Cables /Connectors etc.. : 350/=
4+4 Copper WindedPower Transformer: 2400/=
MOSFET based circuit with heat skins : 550/=
IC Based Circuit Specially Designed for Computers 650/=
——————-
Total Cost of Complete UPS : 4300/=
Now lets compare my UPS with other available UPS in market.
Other UPS: Displays a old analog volt meter.
My: Displays Nokia style battery charging display along with Nokia Style battery bar meter.
Other: 4+4 UPS are bulky , larger in size with poor quality winded transformer and non IC Based circuits that restarts computers.
My: Packed in most small available box in market, having power rating of 1000VA, equipped with IC based circuit that wont restarts your computer.
Other: Uses BJT power transistors for power output and Diodes for charging.
My: Based on advanced MOSFET transistors so no need of conventional BJT transistors and diodes that reduces the size of my UPS.
Other: Cost of UPS that can run a computer without restarting it starts from 7000 and can get an average UPS nearly 12000
My: As I have made it by myself thatswhy cost is reduced I have made complete UPS for Computer under 4500/= (Actual cost is 4300/=)
Other: Due to poor power transformer it utilizes high battery current during operation. Total loss over a fully charged battery is 4.8 to 6 Ampares
My: Due to 100% pure copper transformer winded with proper core it minimizes the losses (Total loss over full battery is 3A)
Other: UPS damages if load exceeds
My: Automatic load sensor, with automatic short circuit protection, UPS switches off automatically in case of short circuit and battery overload. It also beeps and LED flashes when overload / short circuit occurs.
This UPS can operate following at-once easily on a 100A Battery for upto 2.5 to 3 hours easily:
1. One CPU.
2. One LCD Screen.
3. One Ceiling Fan.
4. Two Energy Savers.
5. One Scanner
6. One Printer
7. One TV Device
8. Mini Speakers

Its Superb!! Great Work
Interesting… I also want to purchase this type of UPS. I cant understand that you altered UPS or purchased. very economical..
I have purchased individual parts and circuits, and built it by myself, I have altered circuit for short circuit protection and configure it to work as per my needs.
I want to buy a UPS for my
- Desktop Computer 500 watt
- 1 LCD watt ?
- 2 Energy Saver of 25 watt
- 1 fan of 80 watt
so i can use my desktop computer with lcd with fan and 2 energy savers.
a complete 1 room solution !
please quote the price !
Please provide the circuit with components list and their values.
can i produce it as a product, what will be the cost of production etc, will you help me.

Assalam u alaikum
IS UPS ki Current Value Kya ha
Parts ke price almost same hai just transformer ke price up/down hote rehte hai.
Thanks and best regards
Faraz Ahmed.
Can you please share some video of it. It will be very helpful in understanding and making this ups.
Sir, I want to purchase this type of UPS. I have One Pentium IV computer with HP laser printer and monitor. IF power failure how long it function.
well..the kits you have shown are available in Lahore Hall Road. 500Rs for (4+4) module and 500Rs for the circuit with charging protection etc Microprocessor based ..all features included.
That saves the time of buying every equipment separately and connecting them over Board.
Transformer’s and Box’s are also available
cost varies and depends on the quality of transformer you are purchasing.
You just need to connect them.. Happy Life
Great job faraz.
I will be glad if you can send me step by step guide for connecting Transformer with Mosfet based circuit and IC Circuit Card.
Thanks in advance.

Nice job however it would be much nicer if you can assemble kits yourself and provide a schematic diagram. I have still have to see a Pakistani website providing an advance DIY UPS project with all bells and whistles and it must be a Modified Square Wave not ordinry cheap square wave. If you notice you will find that the chip type in ready made kit is specifically erased and that’s the part I hate most. Europe is going ahead as it is sharing and blooming what ever they can. What do u say?
