Senva is redefining Branch Circuit Monitoring with a next generation technology that simplifies installation and connectivity while providing instant access to data in a user friendly format. The versatile Core Module TM system is a single monitoring solution with peripherals optimized for Branch Circuit and Multi-Circuit Monitoring applications designed to reduce the cost and complexity associated with legacy multi-circuit monitors.

  • Ideal for baseline consumption in premises (e.g., store-to-store comparisons for chains)
  • Activity-based costing in commercial and industrial facilities
  • More informative than an amperage measurement only
  • Great for solid core, split core CTs, and analog for data center
