MDU
The MDU works with the monitoring interface unit to manage batteries, communicate with the UPS and network management system (NMS), and provide man-machine interaction interfaces, communications ports, and permission management for local and remote operations.
The MDU allows you to view the battery voltage, current, state of charge (SOC), state of health (SOH), and temperature reported by the BCU, and save data and alarm information locally.
The ports of the MDU are located on the side and rear of the display panel.
