Eurotherm has announced EPower power controllers with a single driver module to support up to four power modules. The result is the ability to support seven different load configurations. Initially the power modules come in four sizes - 100, 160, 250 and 400 A. Further flexibility is provided by a series of options that allow additional modules to be plugged into dedicated slots for extra I/O or digital communications.0
Connectivity with PLC, SCADA or DCS systems is said to be straightforward with support for common industrial protocols such as Profibus, DeviceNet, Modbus TCP/IP and Modbus-RTU. Software flexibility is based on five major attributes: the devices come preconfigured for “out-of-the-box” use via the order code; firing mode, current and voltage adjustments are also said to be straightforward; configurable I/O; Input mode; and Alarm setting. Predictive Load Management (PLM), one of the controllers’ key features, provides power demand optimization, no phase angle disturbance and a reduction of total harmonic distortion.
