AVR Marelli M40FA640A/A Automatic Voltage Regulator
Our Advantage:
APPLICATION
The Marelli AVR M40FA640A is suitable for Synchronous Generators of
MARELLI MOTORI make, MJB series, size range 160-500 frames. This
regulator is proper to operate on machines rated from 10 up to 2000
kVA. The regulator is fully insulated in order to maintain high
reliability also with severe ambient conditions (high level of
humidity, dust, salt atmosphere), and in case of
high vibrations level. The regulator is proper both for single and
3-phase operation.
REGULATION ACCURACY: ±0.5% steady state conditions, for rated Voltage and PF
VOLTAGE DRIFT: ±0.5% of voltage change for 50°C T amb change
RESPONSE TIME: 1 cycle (20ms-16.6ms)
OPERATING TEMPERATURE: -30°C ÷ +70°C
EXCITER FIELD RESISTANCE: 3.5Ω (min) ÷ 20Ω (max)
