DC88V-DC286V Dc Distribution Panel 32 Branches Detection And ±1% Accuracy Power Monitoring Module ZHCL-3

The ZHCL-3 2.0 developed by Shijiazhuang Tonghe Electronic Technology Co., Ltd. adopts a modular design philosophy to accommodate diverse power system applications. It integrates multiple data acquisition units to ensure rapid and stable voltage/current detection, while dual protocols enable flexible combination of the host unit with underlying modules.

This powerful device features: 2 control busbar current channels, 2 battery current detection channels, 2 battery temperature detection channels, 8 digital output control channels, and 32 digital input status detection channels. Core measurement accuracy reaches ±1% (voltage/current), with temperature detection error of ±3°C, ensuring rapid and stable data acquisition.

Equipped with dual RS485 interfaces for convenient wiring, it supports wide voltage supply from 88~286VDC with power consumption ≤10W. Crucially, this module operates in environments from -10°C to 40°C, withstands 95% humidity and altitudes up to 4000m. Suitable for non-corrosive, non-conductive dust industrial settings, it is widely deployed in substations, industrial control systems, and data centers, delivering precise monitoring and reliable control solutions for power systems.
