APM-MAX-M21-NU-4B

APM-MAX-M21-NU-4B is an APM MAX M21 negative LCD advanced panel meter. Designed for 0-600V DC/AC applications, the APM-MAX-M21 multi-function panel meter is configurable as an ammeter, voltmeter, frequency meter, or power monitor (measuring Watts, VA, and Power Factor). Its unique display merges the clarity of analogue with the precision of digital and features a 25% larger screen than standard APMs, a 60-segment bar graph, a large 4-digit readout, a starburst area for messages and alerts, and a full-colour RGB backlight for real-time alerts. The M21 is customizable to the application requirements, with programable scaling, range, annunciators, backlight and colour settings, dual alarm set-points, two digital outputs, one of which can be used as a 4-20mA analogue output, and communication via MODBUS® TCP/IP and RTU, all in an IP65-protected design. The negative display with colour-changing figures on a black background is for dark environments.
