  • T-VER-8044-100

    The Veris AC Kilowatt Transducer incorporates three split-core AC current sensors and three voltage leads and outputs a signal proportional to kilowatts of power (demand). Accepting an input primary voltage of 480 Volts AC rms, this transducer requires a FlexSmart Analog Module. Because these sensors tie directly into the line, they should be used only by qualified personnel. NOTE: Not recommended for use with variable frequency drives.

    Requires analog port selection during U30 system configuration and use of a S-FS-CVIA when using the H22-001 data logger. When using a U12 data logger, this sensor requires a 4-20mA input cable (CABLE-4-20mA) and external power provided by an AC adapter (AC-SENS-1).
