KWS-AC300 100A Digital AC Power and Energy Meter

Understand how your AC system is performing from one clear display. The KWS-AC300 is an AC power meter that tracks voltage, current, watts, energy, operating time, and temperature. Made for technicians and electrical projects, this digital wattmeter supports AC 50–300V and up to 100A with an external current transformer. Power-loss memory preserves accumulated energy and timing data.

Key Features

• Monitors voltage, current, power, kWh, time, and temperature.
• Measures AC 50–300V across a 45–65Hz supply range.
• 100A model uses an external CT for current sensing.
• LED screen keeps readings easy to view.
• Resettable energy and timing values support repeat testing.

Why Choose Our KWS-AC300 Meter

Separate meters add wiring and use more panel space. This energy consumption meter combines six readings in one compact panel unit. CT-based current measurement also avoids routing the full load through the display module.

Perfect For

Ideal for distribution panels, workshops, equipment cabinets, appliance testing, generators, and electrical projects.
