ADJUSTABLE SWITCHES
ACS2, ACSX2, ASCS2 & ASCSX2 Series
The Adjustable Current Switches are designed for use in any AC current monitoring application
in which you are looking to monitor a particular piece of equipment for equipment failure,
preventative maintenance, status, and electrical load status. The current switches should be
installed on the line side of the power to the electrical equipment. The current switches are
available in both solid and split-core versions which also includes a Patented 35 mm Din Rail
mounting foot for easy installation in panel mount applications. The solid-core versions are a
great choice for new installations or OEM applications in which cost sensitivity, lower trip points
and environmental issues may be of concern. The split-core version of the current switches work
great in retrot applications and for use on service technicians vehicles since one part will work
in most applications and can be easily installed without disconnecting any wires. The adjustable
current switches can be used to determine the run time of your equipment as well as basic load trending applications where you want to know when
how long your piece of equipment runs when logging the contact closures on your building management system or PLC.
Applications: Overload Conditions, Underload Conditions, Normal Operating Conditions, Broken Belts, Belt Slippage, Locked Rotors, Equipment
Failure, Fans, Pumps, Compressors, Motors, Ovens, Industrial Equipment, Lighting Status and Usage, Electrical Load Status, Local Alarms (Strobes
and Audible Alarms), Preventative Maintenance Scheduling
