Bernini Design - Model BeK3 - AMF Controller for Standby Generators
The BeK3 AMF controller is a sophisticated device designed for managing standby generators, particularly in Automatic Mains Failure (AMF) scenarios. It facilitates the seamless transition of electrical loads between the utility power and a backup generator. The controller monitors key electrical parameters and automatically initiates generator start-up when deviations occur. Its robust construction includes a zinc double-coated steel enclosure, providing superior durability and electromagnetic interference protection. The BeK3 AMF controller features advanced functionalities such as a comprehensive 128x64 graphic display for real-time performance monitoring, CANbus integration for engines with ECU support, and Modbus RTU compatibility via RS485 for extensive networking capabilities. With a wide operating temperature range and high ingress protection, it's engineered for demanding environments. The controller also supports a dual generator setup, ensuring reliable power supply during extended utility outages. Additionally, remote monitoring solutions via GSM and TCP/IP are available for enhanced system oversight.The BeK3 AMF controller governs all functions of a standby generator. It automatically manages the connection assignment of the LOAD to MAINS or GENERATOR. The BeK3 AMF controller is the core of AMF panels manufactured by Bernini Design.
It is an Automatic Mains Failure relay. It compares the electrical parameters of the MAINS (that is the Utility Power) with a set of internal settings. When one or more parameters are out of range, the relay triggers the Mains Failure Flag. This could be used to perform miscellaneous functions: disconnect the load and start the engine for example. AMF controllers manufactured from 1980 integrate into one single-board AMF relay and generator controller. The most popular example of it was the AMT910 which soon became Be21
The 128X64 graphic display, operating in a temperature range between -15°C and +50°C, indicates parameters, alarms, and miscellaneous functions. The AMF controller measurements include Vac, Aac, Vdc, kVA, kVar, kW, Energy, Pdf, Hz, hour count, R.p.m., Oil Pressure, Engine Temperature, Battery Vdc (Engine), and Fuel Level. The BeK3 complies with NFPA-110 / NFPA-99 specifications.
