• Three Phase AMP–Hertz Meter : KM-12-A is a meter for measuring
current and frequency, displaying values of all three phases R, S, T
simultaneously.
• Measurement range:
- Current 0.05–10 A (direct connection).
- Current up to 9999 A (when used with CT).
Can be used with Current Transformer (CT) up to 10,000/5 A.
Frequency measurement range: 45–65 Hz
True RMS measurement for high accuracy
Supports communication with a computer via RS-485
Modbus RTU Protocol.
Equipped with LED indicators for operating status and electrical units.
Peak Hold function to display the maximum value in the system.
Display: 7-Segment, 0.56 inch, 4 digits, 3 rows.
KM-12-V has 4 display pages: it displays Phase Voltage, Line Voltage, and Frequency (Hz) measured simultaneously for all three phases at the current moment, as well as Peak Volt Avg. The Peak Volt value is calculated as an average over a 15-minute period. Pressing the up arrow button displays the present voltage values, while pressing the down arrow button displays the Peak Volt Avg. On the Peak Volt display page, the Peak LED will blink during display. The meter can also transmit data via RS-485 Modbus RTU Protocol for logging and recording on a computer.
