5.FAQ:
1.What is uninterrupted power supply
An uninterruptible power supply, also uninterruptible power source, UPS, is an electrical apparatus that provides emergency power to a load when the input power source, typically mains power, fails. A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries, super capacitors, or flywheels.
2.What is the difference between high frequency ups machine and low frequency ups machine ?
Item | High frequency ups machine | Low frequency ups machine |
Input PF | 0.99 | 0.7 |
Efficiency | 85-90% | 75-85% |
Power density | Higher | Lower |
Power device capacity | Less | More |
Weight | Light | Heavy |
Dimension | Compact | Bigger |
Price | Lower | Higher |
Overload ability | Normal | Better |
Anti input sugar capacity | Normal | Better |
Output anti-crush , short circuit capacity | Normal | Better |
N-G voltage | Bad | Better |
Output component | More | Less |
Damage extent of device when it's fail | Higher | Lower |
Stability | Normal | Better |
Compatibility with generator | Bad | Better |
3. How to choose between standard model UPS and long time model UPS?
Standard Model ups machine | Long-run Model ups machine |
Standard model UPS power means within batteries inside UPS, the backup time would be only few minutes at full load | Long-run model UPS power means with external batteries, the backup time would be different according to the battery capacity |
If the backup time at full load is longer, long time model would be your choice , if the backup time at full load is shorter, standard model UPS would be enough | |
4.Does the ups machine work in my country?
YES, we provide different socket and plug according to different country, also will produce the ups voltage and frequency based on your special need.
