Description
The MFM376 SELEC Multifunction Meter is an advanced LED meter designed for versatility in measuring electrical parameters across various systems. It is compatible with 1-phase 2-wire, 3-phase 3-wire, and 3-phase 4-wire configurations. This meter offers precise voltage measurement capabilities, ranging from 11 to 300V (L-N) and 19 to 519V (L-L), with an impressive accuracy of ±0.5% for voltage and current. Additionally, it boasts a frequency accuracy of 0.1% and power factor accuracy of 0.01%, making it a reliable choice for energy monitoring. The MFM376 can effectively measure both active and reactive power, as well as apparent energy with a Class 1 accuracy rating. Features such as maximum/minimum power demand measurement, energy import/export tracking, and %THD measurement up to 31 levels enhance its functionality. The meter also includes RS485 communication capabilities via MODBUS RTU (MFM376-C-CE) and is CE-certified, ensuring compliance with European standards.
