Product Data Sheet Characteristics EPower™ Controller Power Controller 1-2-3-4 phases Power Controller Document number: The EPower™ Advanced SCR Power Controller is a modular multi-channel SCR power controller unit. The EPower current ratings cover ranges from 50 Amps up to 630 Amps (compact variants) and from 800 Amps to 4000 Amps (MC EPower with HPower variants). The voltage rating can go up to a maximum of 690 volts depending on current variants. Its single-driver module can support up to four independent control loops. The driver module offers a wide choice of options boards with the support of 7 Fieldbus protocols over Ethernet and serial industrial communications, flexible I/O, and Predictive Load Management (PLM). Eurotherm iTools PC-based configuration software is used for commissioning and advanced programming, this is available free of charge from the Eurotherm website.
