FPM 100


The FPM100 Digital Multifunction Meter is our latest offer for the low-cost digital power/energy metering market. Housed in a standard DIN form factor measuring 96x96x88mm, it is perfectly suited for industrial, commercial and utility applications. The FPM100 features quality construction, multifunction true RMS measurements and a large, backlit, 7-segmant LCD. Compliance with the IEC 62053-22 Class 0.5S Standard, it is a cost effective replacement for analog instrumentation that is capable of displaying 3-phase measurements at once. It optionally provides four Digital Inputs for status monitoring, two Relay Outputs for control and alarm applications. The standard RS-485 port and Modbus RTU protocol support makes the FPM100 a smart metering component of an intelligent, multifunction monitoring solution for any Energy Management System.
