These field-adjustable current switches combine a current transducer, a signal conditioner, and a limit alarm in a single, self-powered package. The device is available in ac or dc sensing types, in split-core or solid-core configurations, and with a variety of output options. The company says its current switches monitor loads from 1 amp to 250 amps and provide field-adjustable setpoints and reliable, solid-state outputs. According to the manufacturer, current switches are ideal for obtaining electronic proof of flow on fans and pumps, for controlling conveyors, or for real-time monitoring of heater and lamp status.
