Branch Feeder Monitor
Fitting for both new and retrofit projects, SATEC’s Branch Feeder Monitor™,
is a multi-circuit power meter, monitoring up to 18 three-phase power circuits
or 54 single-phase, or any combination. The BFM-II utilizes High Accuracy
Current Sensors (HACS) and is ideal for a wide range of applications,
from monitoring medium-voltage substations through commercial multi-tenant billing
in shopping-centers or office buildings.
t is designed for DIN-rail mounting, equipped with built-in communication ports and
anti-tamper enclosures. Modular expansion allows installation of additional I/O modules
and power supply.
