AC Current Switches are used on non-critical pumps to detect over- and under-current conditions. Available in N.O. or N.C. designs with optional time delays built in. Setpoint Range: 1-150 Amps Output: Isolated Solid State Power Supply: None Self Powered Response Time: <120 ms Frequency: 6-100 Hz Isolation Voltage: 1,270 VAC Environmental: -40° to 133° F (-40° to 55° C), Typical Agency Approval: UL 508 (USA & Canada)*, CE DC Designs Available * Most Models	AC Current Switches Click here for more information. Over-current & Under-current Protection, Time Delay		AC Transducers Click here for more information. Current Monitoring, Load Measurement	AC Transducers are ideal for monitoring and recording the characteristics of pump motors. Analog outputs include 4-20 mA, 0-5 or 0-10 VDC for easy interface. Input Range: 0-2000 Amp Output: 4-20 mA (True RMS Option), 0-5 or 0-10 VDC Response Time: < 300 ms, Typical Frequency: 10 to 400 Hz Accuracy: < 1.0% FS Environmental: 58° to 149° F (-50° to 65° C) Typical Agency Approval: UL 508 (USA & Canada)*, CE DC Designs Available * Most Models
