FEATURES
* Double conversion online design, output zero transfer time;
* Adopt DSP digital control, excellent performance indicators, make the control system more steady and reliable;
* Adopt Active Power Factor Correction (PFC) technology, the input power factor is close to 1, which greatly reduced the
pollution to the grid;
* Ultra-wide input voltage range;
* Input frequency range is 40~70Hz, ensure stable operation when connected to various fuel generators;
* With LCD+LED real-time display, users can intuitively understand the UPS operating status;
* With self-diagnosis function, it can detect hidden faults of UPS in time;
* N+1 parallel redundant design, can realize 3 parallel connections, greatly improved system reliability;
* With AC input over, under voltage protection, output overload protection, short circuit protection, temperature protection,
battery under voltage warning protection and battery overcharge protection;
* The whole machine efficiency is up to 90%. Reduce the power loss of the UPS and save the user’s cost;
* In the absence of city power, the battery can be cold-started directly;
* Input neutral line detection function to avoid reverse connection of UPS mains input neutral line and live line;
* When the utility power is interrupted, the UPS will discharge in battery mode; when the utility power recover, UPS will turn on
and charge the battery automatically, to achieve unattended operation;
* Standard RS232 communication interface enables UPS and computer to realize multi-function and multi-purpose monitoring and
management operations through computer window, and can install SNMP card (optional) to realize UPS remote monitoring function.
