Trumeter APM-PWR-APO- APM 3-Phase Power Meter Modbus RTU 100-277V AC PSU

The APM Power Meter is a versatile energy meter for single, split, or 3-phase networks, supporting inputs from 0-600V AC (L-L), 10-300V AC (L-N), and up to 10,000 kA via CT. It measures voltage, current, power (W, VAr, VA), frequency, power factor, THD, max load %, and total energy (kWh/kVAh).

Its unique display ensures clear visibility with a large readout, bar graph, and color-changing backlight for instant feedback. Fully customizable via free APM software, it allows scale and range adjustments, 10 alarms, color settings, messaging, and programmable CT/PT ratios.

Equipped with two digital (open collector) outputs, one analog (4-20mA) output, and Modbus RTU support, the APM Power Meter delivers real-time monitoring and control of electrical performance.
