Multi-channel Power and Energy Meter
Fitting for both new and retrofit projects, SATEC’s Branch Feeder Monitor™, is a multi-circuit power meter, monitoring up to 12 three-phase power circuits or 36 single-phase, or any combination. The BFM136 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.
The BFM136 is a highly reliable piece of equipment featuring a rugged design for a long life of uninterrupted service.
