Senva C-2350VFD : Self-Calibrating Split-Core VFD Current Switch, 0.5–135A, Made in USA, 7-Year Warranty
The Senva C-2350VFD AutoSet™ Current Switch is a self-powered, split-core sensor designed for precise monitoring of variable frequency drives (VFDs) and constant volume motor loads. It automatically calibrates to detect flow on fans and pumps, minimizing false alarms and reducing installation time. This sensor helps identify motor issues like belt loss, coupling shear, or mechanical failure. Operates from as low as 0.5A with a solid-state, normally open output (1.0A @ 30VAC/DC).
Common Applications
- Monitoring proof of flow in VFD or constant-speed fan and pump motors
- Detecting motor undercurrent conditions like belt loss and mechanical failure
- Ideal for BAS, HVAC, and energy management systems
