Three Transducers In One Housing Measure Three Currents

The HTT series of PCB-mounted current transducers let users measure three currents with a single unit. The five transducers, which measure maximum currents ranging from 25 to 150 ARMS, allow three-phase currents to be monitored independently by a unit occupying a mounting area of only 16.8 cm2 and with a height of only 29 mm. The transducers have three 12- by 10-mm apertures for the primary conductors and are securely mounted by four metallic pins, which are soldered to the PCB. Secondary connections for power supply, 0 V, and the three voltage outputs are also made to the pc-board by pins. The five models use the same housing and cover nominal current measurements of 3 by 25, 50, 75, 100, or 150 ARMS, working with a bipolar power supply of ±12 to ±15 V. The use of open-loop Hall-effect technology allows measurement of dc, ac, or pulse currents and provides galvanic isolation between the primary and output circuits, withstanding a test isolation voltage of 2.5 kV rms/50 Hz/1 min. The transducers conform to the EN 50178 standard and are CE marked according to European Directive 2004/108/EEC. LEM USA INC., Milwaukee, WI. (800) 236-5366.
