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. * Fully configurable digital power meter for single, split, and 3-phase networks * Measures Active (W), Reactive (VAr), and Apparent (VA) power * Large backlit LCD with dynamic colour changes (green, red, white) for instant alerts * Remote monitoring via Trumeter Cloud when paired with the IoT Gateway * Two independent opto-isolated digital outputs and one 4-20mA analogue output * Standard Modbus® RTU communication for seamless integration * User-programmable scaling, CT/PT ratios, and custom alarm messages * Starburst display area for messages and critical alerts * 10 programmable alarm setpoints for real-time monitoring https://elecena.pl/product/28981116/trumeter-apm-pwr-apo-apm-3-phase-power-meter-modbus-rtu-100-277v-ac-psu 2025-06-20 https://elecena.pl/product/28981116/trumeter-apm-pwr-apo-apm-3-phase-power-meter-modbus-rtu-100-277v-ac-psu 2026-03-30 https://elecena.pl/product/28981116/trumeter-apm-pwr-apo-apm-3-phase-power-meter-modbus-rtu-100-277v-ac-psu 2026-06-29 https://elecena.pl/product/28981116/trumeter-apm-pwr-apo-apm-3-phase-power-meter-modbus-rtu-100-277v-ac-psu 2026-07-22
