>Features
◇It has the characteristics of small size, simple structure, wall-mounted installation, and does not occupy space.
◇Adopt the unique modular design of switching power supply, redundant hot backup.
◇Ultra-wide voltage input range, strong applicability to the power grid, can be used in places with relatively harsh environment.
◇The charging module can be plugged and unplugged with electricity, and it can be maintained online, which is convenient and fast.
◇The charging module adopts foreign new soft switch technology, which has high conversion efficiency and low electromagnetic interference.
◇Hardware low-difference current sharing technology, the typical value of output current unbalance between modules is ±3%.
◇The charging module has passed CE safety regulations and electromagnetic compatibility certification, which is reliable and safe.
◇Open interface design, with powerful communication function, it is convenient to connect with the substation RTU device or the power plant computer monitoring system DCS.
◇Automatic battery management and protection, real-time automatic monitoring of battery working status and various parameters, with the use of battery inspection instrument, more convenient to monitor the fault status of the battery pack and its individual batteries.
◇Built-in insulation monitoring relay, external insulation relay or insulation monitor can also be installed, flexible.
◇Convenient and real-time monitoring of DC bus insulation status.
Note: Signal boxes can be added according to user needs to realize the alarm function of accident signal or warning signal.
Two AC inputs can be selected (one of which can be selected PT100VAC power supply), and PT power supply automatically limits the output power.
