Suitable for systems up to 38AH / 220V, or 65AH / 110V:
Charging Modules: Accommodates up to 3 units of WD220D03-3A (or WD110D05-5A) natural cooling digital intelligent modules.
Voltage Reduction Unit: Features automatic silicon stack voltage reduction function, controlled by CPU intelligent control. Maximum current: 2.0A; surge current: 30A / 0.5s. Output voltage of the silicon stack is adjustable. For 110V systems, maximum current: 3.0A.
Monitor: Equipped with LCD display, Chinese character menu, and keypad operation. Capable of system parameter setting, system operating parameter display, system fault indication, and system calibration.
Battery Auto-Management: The monitor has automatic battery management function, capable of monitoring battery voltage, control bus voltage, control bus current, battery charge/discharge current, and module status.
Battery Inspection Unit: The monitor can be connected to a battery inspection unit (DCXJ-19) to perform voltage detection on 18 battery cells.
Communication Interface: Provides RS232/RS485 communication interface, with two communication protocols available: CDT and MODBUS, enabling connection to the power plant automation system.
Input Power: Provides one single-phase AC input and one PT100 input. When powered by PT, the system automatically limits output power with output current limiting at 2.0A; for 110V systems, output current limiting at 3.0A.
Protection Functions: Includes bus insulation monitoring, bus ground fault alarm, battery circuit breaker trip alarm, and other functions.
Module Hot-Swappable: Modules are hot-swappable.
Cable Entry/Exit: Bottom entry and bottom exit (cable outlet hole size: 4 × Φ30 mm).
