Product Description

Model 1055 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 300Aac,  an overload of 500Aac and the transducers withstand, without performance degradation or damage, overload transients 10 times the applicable current range for 250m-seconds.

The 1055 Series delivers high performance accuracy over a temperature range from -40°C to +85°C and measures input current with a frequency range from 50 to 60Hz.  The transducers are low powered (30mA typical @ overload), operate with a supply voltage from +5 to +35Vdc and produce a 4-20mA output into a load resistance from 0 to 1400 Ohms.

The 1055 AC Current (RMS) Transducers are light weight, non-intrusive, come standard with a barrier interface and are UL and CSA Recognized.
