KWS-AC300 Digital AC Voltmeter Ammeter Power Energy Meter 50–300V 0–100A LED Wattmeter with Reset Function

Take full control over your household, generator, or industrial electrical monitoring with the KWS-AC300 Digital AC Power & Energy Meter. Designed for real-time electrical diagnostics, this multi-functional panel meter accurately measures AC voltage (50–300V), current amperage (0–100A), active power (wattage), cumulative energy consumption (kWh), operating timing, and internal temperature simultaneously. Equipped with a high-definition full-color LED display, it offers wide viewing angles and crisp visibility in low-light environments. Featuring a built-in electric energy reset function, internal memory power-off protection, and a split/close-type current transformer (CT) for safe non-contact measurement, the KWS-AC300 is an essential diagnostic tool for distribution boxes, solar inverter outputs, generator setups, and workshop machinery.

Key Features

• 6-in-1 Multi-Parameter Monitoring: Simultaneously displays AC Voltage (V), Current (A), Active Power (W), Cumulative Electricity (kWh), Run Time, and Temperature (°C).

• Safe Non-Contact Current Transformer (CT): Measures high AC currents up to 100 Amps safely without requiring direct contact with live high-voltage wiring.

• Energy Reset & Memory Backup: Features a dedicated button to reset accumulated kWh consumption for specific tests while retaining total data during unexpected power cuts.

• Vivid Color LED Panel Display: High-definition multi-color display screen provides wide-angle readability day or night.

• Flush-Mount Panel Installation: Compact snap-in frame housing mounts easily into electrical cabinets, breaker panels, solar power boxes, and DIY generator setups.

Why Choose Our KWS-AC300 AC Power Meter

Traditional analog meters are difficult to calibrate, take up excessive space, and only show a single variable like voltage or amperage. Standard digital meters lack energy accumulation reset functions and temperature tracking, leaving you blind to thermal stress in electrical boxes or specific appliance power consumption over time. The KWS-AC300 combines 6-in-1 multi-metric LED tracking, safe 100A CT sensor isolation, one-touch kWh resetting, and durable snap-in panel installation—giving your solar inverter setup, generator panel, and home electrical monitoring an instant professional upgrade.

Perfect For

• Monitoring electrical output on solar inverters, gas generators, off-grid power systems, and main electrical breaker panels

• Tracking real-time electricity usage and cumulative kWh consumption for workshops, air conditioners, heaters, and EV chargers
