EMS-Series

Modbus Energy Management System

Features and Benefits

Overview

An EMS-Series is an extremely versatile Universal Input Energy power meter with a wide range of current measurement inputs. It can handle voltage-transduced currents, direct voltages, and Rogowski sensors with voltage output up to 333 mV. This instrument offers multiple insertion modes, including single-phase and three-phase 3/4-wire types, and is fully compatible with a range of communication protocols, including ModBUS RTU, ModBUS TCP-IP, and Peer-To-Peer.
