The CS-AC series products are self-powered, operate over a wide frequency range, and contain a universal solid-state output that will trip when a field adjustable setpoint is exceeded.The CS-AC series are designed to withstand harsh industrial environments. They can be mounted in virtually any position and either panel mounted using the built-in mounting bracket or hung directly on the wires and secured with a wire tie. The split core case design makes installation in new or existing applications very quick and easy since the product can be snapped shut around the wire to be measured.The built-in current transformer physically isolates the high current from the limit alarm circuitry making this product much safer to use than other products or methods.Configuration and installation are simple. The switch is powered by the induction from the line being monitored. The AC current is measured by the built-in current transformer, eliminating the need for both power and input wiring. Once installed around the wire to be measured, only two wire connections are necessary for the solid state output.The CS-AC-1 includes a"normally closed" solid state output. Both models include a status LED that flashes slowly if the setpoint has not been exceeded (nonalarm condition) and flashes rapidly if the setpoint has been exceeded (alarm condition).
