ASC Series Current Operated Switches are precision calibrated at the factory per customers’ specifications and guaranteed within 1% accuracy. Because the switch is factory calibrated eliminating the need to turn the potentiometer to the correct position in the field, installation time is substantially reduced resulting in a significant cost savings. The ASC combines a current transformer, signal conditioner and limit alarm into a single package for use in status monitoring or proof of operation applications and is perfect for OEM applications where the need for a limit alarm is required. Available in a solid-core or a split-core case to maximize ease of installation.
 

Current Sensing Switch Applications

Electronic Proof of Flow Current operated switches eliminate the need for multiple pipe or duct penetrations and are more reliable than electromechanical pressure or flow switches. Conveyors Detects jams and overloads. Interlocks multiple conveyor sections. Lighting Circuits Easier to install and more accurate than photocells. Electrical Heaters Faster response than temperature sensors.

Factory-set trip points are ideal when there are several loads, all using the same motor to drive the fan blades. Air Handling Fan Protection × Factory-set trip points are ideal when there are several loads, all using the same motor to drive the fan blades.
