The HKD KWS-AC300 LCD Power Meter is a multifunction AC digital measurement module designed for accurate, real-time monitoring of electrical systems. It integrates voltage, current, power, energy, frequency, time, and temperature measurement into a single compact unit, making it an ideal solution for electrical panels, workshops, laboratories, solar systems, generators, and industrial or DIY power monitoring projects.
This unit operates on AC 50-300V systems and supports current measurement up to 100A using the included closed-type current transformer (CT), allowing for safe, non-invasive current sensing without breaking the main power line. The high-contrast LCD digital display provides clear and readable real-time values for all measured parameters.
Designed specifically for 220V AC electrical systems, the KWS-AC300 is well-suited for both single-phase residential and commercial applications. It enables users to monitor active power consumption (W), total energy usage (kWh), frequency (Hz), and operating temperature, helping improve energy efficiency, detect overload conditions, and maintain system safety.
With its compact form factor, easy wiring integration, and multi-parameter display, the KWS-AC300 is perfect for distribution boards, inverters, UPS systems, power tools, test benches, EV charging setups, and energy management systems.
