Designed for a wide range of power monitoring applications, the APM-MAX combines the instant visual representation
of an analog meter with the speed and accuracy of a digital meter for instant recognition and precision measurement.
The large 81.5mm x 66mm display features a two-line display, programmable scale, alarm set-points and colorchanging, full color RGB backlight for instant alerts.
APM-MAX-M21: for high voltage applications; configurable as an ammeter, volt meter, frequency meter or power monitor (Watts, VA & Power Factor).
APM-MAX-M23: for low voltage applications; configurable as a process meter or to be used in conjunction with a shunt.
Both models feature digital and analog outputs and serial MODBUS® RTU as standard (ethernet MODBUS® also available) for communication
with other components in a system as well as an IP65 rating and our industry leading three-year warranty.
