DEIF AGC-4 Mk ll Automatic Generator Set Controller

Product Description

DEIF AGC-4 Mk II is a new-generation multifunctional automatic genset controller, delivering an integrated solution for measurement, control, protection, synchronisation and power management. It can work standalone for Automatic Mains Failure (AMF) operation, or network with multiple gensets to build grid-parallel or island power management systems. It features Close-Before-Excitation, enabling backup power delivery within 6 seconds. N+X redundancy and dual redundant CAN bus are supported. It is compatible with hybrid microgrids including PV and battery energy storage, compliant with major global grid codes. It serves as the core controller for mission-critical power systems and works with DEIF TDU107 touchscreen HMI.
