Being part of Efacec portfolio for Digital Substation solutions, the MCU 500 is a state-of-the-art IED for near-process applications and integration of smart power
equipment in process bus architectures, including both stand-alone merging unit (SAMU) function for current and voltage signals acquisition and circuit breaker
and switch controller functions (BIED) for interfacing switching devices.
The MCU 500 enables several communication network architectures, including zero-time recovery protocols and accurate time synchronization from several
sources and it is suitable for distinct applications, covering Transmission, Sub-Transmission and Distribution substations, supported on multiple product options
that enable fit-for-purpose and cost-effective solutions.
Object orientation and state-of-the-art toolset, combined with pre-configured application templates, allow straightforward engineering throughout the system
life-cycle without compromising user requirements. Designed with IEC 61850 and other open standards in mind the MCU 500 is future-proof and can also be
seamlessly integrated in multivendor distributed systems.
