Split-core Current Sensors from Eaton Corporation

The CurrentWatch EPRM Series from Eaton’s electrical business is a family of DIN-rail compatible, split-core current sensors. Product features include a large aperture, switch-selectable inputs and outputs and isolation between primary and secondary circuits. A patented technology eliminates the use of a magnetic core and protects the sensor against saturation and damage, which can occur from continuous exposure to high currents. Models available up to 400A and with 0 – 5/0 – 10V DC or 4 – 20 mA outputs as standard.

Product Features

True RMS Output Models Available — True RMS technology is accurate on distorted waveforms like VFD or SCR outputs

Switch-Selectable Input and Output Ranges — Field selectable input accommodates multiple AC current ranges, while voltage output models offer choice of 0 – 5V DC or 0 – 10V DC analog outputs

Application Versatility — Supports input ranges of up to 400A and standard 50/60 Hz or distorted (VFD, SCR) loads

Agency Approvals and Patented Technology — CE Approved and UL 508 Pending with a patented technology that eliminates problems inherent with magnetic technology such as core saturation
