4) Perfect Protection
Perfectly system protection functions: It has AC over-voltage, under-voltage, output over-voltage, under-voltage, output overload, short circuit protection, inverter, rectifier over-temperature protection, voltage under-voltage warning, battery over charging protection and other protections in one to ensure the system to operate stably and reliably.

5) Powerful Redundant Parallel Connection Function
Durable and reliable design of industrial-type modular structure, combined with full digital DSP control technology core system, make this product not only can be used for N +1 / N + X redundancy and the ability of enlarge the capacity, but also permit different power and different times of the UPS could be in parallel. It greatly reduced the user’s pre-and post-purchasing costs, and increased capacity costs, but also expanded upper spaces of increasing capacity.

6) Powerful communication system
The standard equipped with RS232 interface, dry contact relays, emergency switching device EPO input interface.

7) Low-power dissipation but high-efficiency
To achieve more than 98% of ultra-high efficiency under ECO economic model, which can effectively bring down the amount of electricity, and effective in accordance with the requirements of energy-saving target of the country.

8) Prediction warning system
LCD panel automatic detection function and timely warning in advance, with the boot self-diagnosis function. It could avoid the hidden danger in time due to UPS’ failure, which caused risks. Also it could automatically alarm by setting the battery discharge to standby time is less than a set value.

9) Humanized panel display
Humanized panel settings, the users can set system parameters, date, output voltage, battery capacity, alarm function, light-load shutdown, system boot time, MODEM settings, such as orders, also it can be up to 120 abnormal failure information for users to query.

10) Super-strong environment adaptability
This product has superior environmental adaptability, wide AC input range, greatly reduces the frequency of battery using, and effectively extends the battery life.

11) Powerful Overload Ability
Using the pure-online double conversion technology, with the output isolation transformers, static bypass, and maintenance bypass.
Inverter Overload Ability reached 110% / 125% / 150% overloading time can last for 300min/10min/1min.
Bypass Overload Ability reached 150% / 170% / 250% overloading time can last for 60min/10min/1min.
