Product Details :

Part No.:
M40FA640A/A

Descriptions:
Marelli Automatic Voltage Regulator (AVR) Mark I for MJB 250 / 315 / 355 / 400 / 450

The voltage regulator type "MARK I", is suitable for Synchronous Generators of MARELLIGenrators 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.

Technical Data:

Regulation Accuracy: +/- 0.5% steady state conditions, for Voltage and PF
Voltage Drift: +/- 0.5 % of voltage change, for 50 oC T amb change
Respond Time: 1 cycle
Operating Temperature: -30 oC ÷ +70 oC
Exciter Field Resistance: 3.5 ohm (min) ÷ 20 ohm (max)
