■ Use unique modular design of switching power supply to keep redundant backup.

■ With extra-wide input voltage range and strong applicability of powernetwork, it can be used in the relatively bad

surroundings.

■ The charging module is electricity-swappable, fast and easy for online maintenance.

■ The charging module adoptsthe latest international soft-switching technology, as to achieve hightransformation

efficiency and little electromagnetic interference.

■ With low differential automatic current technologyof hardware, the standard value of output current imbalance

between modules is 3%.

■ Its open interface design is applied with powerful communication function, which conveniently connects to RTU

device of substation or DCS of computer monitoring system.
