high reliability
Using digital control technology and perfect protection circuit, the stability is good
The power device adopts the imported IGBT module design, and has strong overload and shock resistance ability
Using double conversion technology and static electronic bypass technology, zero switching time is realized
Extremely wide input voltage, frequency range, reduce the battery discharge opportunity, extend the service life of the battery
Adopt the advanced automatic switching constant current constant voltage charging technology and float technology, to maximize battery activation
With a super cold start function, in the absence of electricity, the cold start can be carried out with full load to meet the emergency needs of users
Output accurate phase synchronization with the power grid to improve the reliability of the static electronic bypass

High Compatibility
Wide range of input and frequency range of power supply reduces the requirement of UPS for input power, and can be compatible with any form of power, including industrial power generation, wind power generation and other applications

Humanization
Friendly man-machine interface design, the use of Chinese LCD LCD display, UPS running state at a glance, so that the man-machine communication zero distance
LCD show the content: machine type, input and output voltage, frequency, load capacity, battery capacity, temperature inside the machine, working condition, working mode and fault state, etc.
The maintenance is simple: the internal use of modular design, the structure is concise, fluent, clear

High environmental protection
The whole machine adopts advanced anti electromagnetic interference technology, conforms to international standards, has good electromagnetic compatibility, and reduces or even eliminates the electromagnetic interference to the equipment to the maximum extent
