Autoset-VFD Current Switch
Key Points
Self-calibrating for proof of flow
0.5-135A range
N.O. 30VAC/DC output
Optional command relay
UL/ULC, CE listed
RoHOS compliant
Applications
Detecting belt loss, coupling shear, and mechanical failure on variable frequency drives and constant volume fans and pumps.
The AutoSetâ„¢ VFD self-calibrates to detect proof of flow on both variable frequency driven and constant volume motors on fans or pumps. The C-2350VFD automatically set the proper threshold, eliminating false alarms associated with varying frequencies. Detects motor undercurrent conditions such as belt loss, coupling shear, and mechanical failure on fans and pumps while reducing installation time. New super low 0.5A turn-on--totally self powered!

Self calibration for proof of flow on fans and pumps
Works without costly 'training' of sensor - our sensors are just plain smarter!
No need to open hot starter enclosures - save on labor as well as improve safety
Only VFD sensor line capable of functioning on VFDs to 0.5A
Sensor is always properly adjusted—no call backs
Push-button and LED interface:
Slow blink = normal operation
Fast blink = alarm
Fast learn mode (optional): Press/hold button 1 second, LED makes 2 fast blinks.
Go/No mode (optional) : Press/hold button 5 seconds, LED makes 3 fast blinks.
Split-core with optional command relay
Easy installation and provides stop/start/status in unitary device—saves component and installation space/cost
Maintenance-free—no call backs
Superior to differential pressure sensors
Industry leading 7 year warranty
