Product Overview
Description

SDE330-C100 micro DIN rail 3 phase power analyzer is designed special for renovation project of energy management (EMS). It has 3 external split core CTs (5~600A) or 3 Rogowski coils (200~6000A), so we don't need to dismantle bus to install it. By its DIN rail installation, it is very suitable to be used with breakers, contactors.
Besides electrical energies, it can measure all the parameters on the electrical networks, such as currents, voltages, active powers, reactive powers, apparent powers, frequency, power factors and 4 quadrant energies. It is designed as just 2 modules, so it can be installed in any so small space or to use it as multi channel 3 phase analyzer. Every SDE330-C100 has a RS485 interface to transfer its measuring data to other master devices, such as PLC, data center computers.
SDE330-C100 has good cost performance, as an intelligent unit and a digital electrical data collection unit, it has been widely used in many intelligent systems.
