The HT Italia HT4004 is a 10/100A AC/DC transducer in a rigid clamp form factor. It measures current from 0.1 A to 100 A AC/DC and converts the measured current into a proportional low-level voltage output, with a maximum output signal of 1 V AC/DC delivered into a minimum external load of 10 kΩ. The output follows a fixed scaling ratio so the host instrument reads current as a clean voltage signal.

A clamp-style current transducer lets a user measure current without breaking the circuit, by closing the jaws around a conductor and sensing the field it produces. The HT4004 outputs a scaled voltage suitable for feeding a measuring instrument, and its accuracy is characterized for both DC and AC current as well as for AC power measurement at stated power-factor conditions.

ValueTronics supports the HT4004 from our own 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, where we stock and hold our inventory rather than sourcing to order.
