Specifications
Mounting Style DIN Rail

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 to commercial multi-tenant billing in shopping centers or office buildings. DIN-rail mounting, built-in communication ports, anti-tamper enclosures. Modular expansion allows additional I/O modules and power supply. Cost-effective: saves on installation costs and space Multi-circuit: Modular options – up to 18 three-phase or 54 single-phase loads Dual Input Voltage: 2 parallel measurements for two independent 3-phase power sources (VIM optional) Revenue Meter:
