This KWS‑DC200‑100A is a multifunctional DC power monitor equipped with a 100A external shunt for high‑current measurement. It accurately measures DC voltage 0‑200V, 0‑100A current, power, energy, ampere‑hour, timing and temperature on a vivid color LCD screen for real‑time data reading. Designed with power‑off memory function, it preserves accumulated data after power cut‑off and supports manual data reset for different testing cycles. Featuring external shunt structure, heat generated by heavy current is isolated from the meter body to improve stability and service life. Widely applied in solar power systems, battery banks, RV and DIY DC projects for energy consumption tracking. Simple panel‑mount installation and dual power supply modes bring flexible onsite deployment.
