Overview

The Trumeter APM-MAX-M21-PU-4R is a versatile, panel-mount meter designed for high voltage applications. It functions as an all-in-one unit configurable to measure amps, voltage, frequency, or power (Watts, VA, VAr, and Power Factor). This model features a positive, backlit LCD display with a programmable RGB backlight capable of 256 colors for clear status indication and user alerts. The APM-MAX-M21-PU-4R includes two independent digital outputs and one analog output, switchable between 4-20mA or 0-20mA, for integration with PLCs, beacons, or sounders. Power is supplied via a universal 100-240 VAC PSU. Communication is handled through Modbus RTU over RS485. The meter offers 1% accuracy for voltage, amperage, and frequency measurements. It supports single-phase (2-wire, 3-wire split-phase) and three-phase (3-wire, 4-wire) network configurations. The APM-MAX-M21-PU-4R has a 102mm x 102mm panel mount size and a depth of less than 75mm. Advanced features include front panel navigation buttons and a USB port for custom user settings via free software. This meter is ideal for modernizing equipment and enhancing operational visibility in industrial settings.
