Sensing Solutions

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.

For typical applications of the CurrentWatch™ EPRM Series, see listing below.

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

Typical Applications

• Motor Control Centers — Motor status monitoring for pumps and conveyors, and can be used with panel meters for inexpensive indication of motor current status
• Automation and Data Logging — Loop-powered units help conserve data logger batteries and 0 – 10V/4 – 20 mA outputs are ideal for remote monitoring and alarm functions and are compatible with most automation systems and PLCs
• VFD Controlled Loads — Monitoring VFD output indicates how the motor and attached load are operating

Approvals

• UL Listed (Pending)
• C-UL Listed (Pending)
