What is UPS?
◆ What is UPS?
- UPS : Uninterruptible Power System (or Supply)
- When the power supply (source) was shut off, UPS provide the
back-up power for memory and support the operating power in
short term
◆ Why does UPS need?
- High-tech semiconductor equipment can be damaged or make
errors by Instant Voltage Drop, Momentary Power Failure &
Harmonic Distortion etc.
- The stability of power source for high-precision device or equipment
such as office automation, facility automation. telecommunication
system etc. is essential.

UPS System
- 1/3
◆ Case #1: Applying only EDLC without Battery
- Function : Short-term Back-up power for momnetray power failure (within seconds)
- Application :
* High-precision Equipment
=> To prevent errors caused by unstable power source (AC110V or AC220V)
* High-precision Medical Equipment, High-tech Semiconductor Equipment
=> To support the power source for data back-up and prevent instant voltage drop when
power failure within seconds.
- Operation :
* EDLC Provides DC Power directly to application (DC Power Source) or to inverter (AC
Power Source) when power failure.

◆ Case #2: Applying only Battery withour EDLC
- Function : Long-term Back-up power of main power source when power failure
- Application :
* General Industrial Equipment (Long-term main power source Needed)
=> To support main power source
=> The application doesn’t need rapid response time for power back-up.
- Operation :
* Battery provides DC Power to inverter when power failure.

◆ Case #3: Applying EDLC & Battery
- Function : Short-term Back-up power for momnetray power failure (within seconds) & Long-term
Back-up power of main power source when power failure (Hybrid Function)
- Operation :
* Momentary power failure -> EDLC provides DC power with high speed response time to inverter.
* Continued power failure -> Battery provides DC power to Inverter for long time.
