D-Vo – Marelli Digital AVR
Marelli Digital AVR, Model D-Vo (10024470)
$8,265.00 SGD
The Marelli Digital Regulation System included in D-Vo series are microprocessor-based electronic devices for the set-up and monitoring of the excitation system of Marelli generators with frame size ranging between 400 and 900. The configuration of the system and control parameters makes the D-Vo series regulators flexible and suitable for a wide range of applications. These regulators are completely resin-bonded and isolated to keep operating reliability even in difficult working conditions (high levels of humidity, dust, salty atmosphere) and in presence of vibrations.
D-Vo can be used in the following operating modes:
- AVR mode: D-Vo regulates the generator voltage.
- FCR mode: D-Vo regulates the generator exciter stator current.
- PF mode: D-Vo regulates the power factor.
- VAR mode: D-Vo regulates the reactive power.
