Advantages
  • Less voltage impact on front-end equipment;
    - Input TDHI is less than 3% and input power factor reaches 0.99.
    - The system has a delay function once the power is switched on, so that causing less voltage impact on front-end equipment such as generator and etc. in order to reduce machine overloading.
  • Multiple charging modes for battery protection;
    - Two-stage battery allows charging protection.
    - Auto temperature compensation to ensure longer battery lifespan.
    - Optional battery capacity expansion for extra charging demands.
    - Auto battery aging test for safety assurance.
    - Cycle charging strategy is able to maintain your battery condition to prolong the lifespan.
    - The system test-charges the battery in case the battery voltage is inconsistent after replacing.
  • The inverter capacity is enlarged to ensure long-term operation in 115% work load (power factor 0.8);
  • No matter the back-end load belongs to 0.9 inductive load or 0.9 capacitive load, the active (real) power will not decrease;
  • Overall efficiency is larger than 95%;
  • DSP (digital signal processor) ensures signal static/dynamic features for micro-processing during system operation;
  • Multiple intelligent communication methods realize remote management.

Why Do We Need UPS?

Electricity interruptions can produce serious complications if vital systems go down even if it is only momentarily. For example, a power outage in a data center full of servers hosting services like email systems, can result in huge economic losses as it can bring businesses to a standstill. According to research, UPS systems save billions of dollars in lost data and productivity caused by electricity interruptions.
