Product Description

Model 1070 AC Current (RMS) Transducer provides an isolated 4-20mAdc output proportional to the True AC RMS input current. The transducers are operated in a two wire loop power configuration, with an input current range from 2Aac to 250Aac and an overload of 500Aac.

The 1070 Series delivers high performance accuracy over a temperature range from -40°C to +85°C and measures input current with a frequency range from 20 to 2KHz, with Crest Factors up to 4. The transducers operate with a supply voltage from +12 to +32Vdc and produce a 4-20mA output into a load resistance from 0 to 300 Ohms.  The transducer’s molded construction with the internal components encapsulated withstands, without performance or mechanical degradation, applications with shock, vibration and humidity requirements. In addition, the 1070 Series is ideal for applications where the input waveforms are phase angle fired, chopped or distorted.

The 1070 AC Current Transducers are light weight, non-intrusive and are available with a barrier, connector or d-sub connector interface, with the connector and d-sub connector options available with mating connectors.
