VFD & Constant Volume

AutoSet™ Current Switch

Self-calibrating for proof of flow NEW!
0.5-135A range
N.O. 30VAC/DC output
Optional command relay

Energy Monitor
DESCRIPTION APPLICATIONS E474343
The AutoSet™ VFD self-calibrates to detect proof of flow on both variable ▪ Detecting belt loss, coupling shear, and
frequency driven and constant volume motors on fans or pumps. The mechanical failure on variable frequency
C-2350VFD automatically set the proper threshold, eliminating false drives and constant volume fans and
alarms associated with varying frequencies. Detects motor undercurrent pumps
conditions such as belt loss, coupling shear, and mechanical failure on
fans and pumps while reducing installation time.
