Analogue Voltage Regulators
Marelli Motori analogue regulation systems are suitable for low and medium voltage machines. The
regulators are fully insulated in order to mantain high reliability also with severe ambient conditions (high
level of humidity, dust, salt atmosphere) and in case of high vibration level. The AVRs can work both for
single and three phase operations.
Marelli Motori digital regulation systems provide functional and reliable solutions for the excitation control
of synchronous generators.These highly integrated and robust AVRs are fully configurable and guarantee
easy commissioning, monitoring and maintenance by user-friendly proprietary HMI (human-machine interface)
A wide range of built-in control functions, protections and operating modes make Marelli Motori digital
AVRs flexible and suitable for a wide range of applications, including marine, hydro and cogeneration. Our
automatic voltage regulator, MEC 100 is DNV type approved.
