Intelligent Data Acquisition & Control Unit for DC Systems
The ZLCL Branch Measurement Module is a core monitoring unit developed by Shijiazhuang Tonghe Electronics Co., Ltd. specifically for HVDC (High Voltage Direct Current) systems and DC Power Panels.
Adopting a modular design philosophy and powered by high-speed processing chips, this module provides comprehensive real-time monitoring of voltage, current, switch status, and battery temperature within DC systems. It uploads data to the main monitoring host via RS-485 or CAN bus, making it an ideal choice for constructing intelligent DC power distribution systems.
