MECC ALTE DER2 AUTOMATIC DIGITAL VOLTAGE REGULATOR

Regulator Mecc Alte DER2 fully digital voltage-controlled for synchronous alternators, prepared for stand-alone operation and calibration.

MECC ALTE DER2 natively includes USB port for monitoring and control from computer and HDR module.

High Dynamic Response allows faster reduction of excitation current than conventional controllers and consequently lower transient overvoltage as a result of load shedding.

The supervisory unit may consist of a personal computer, another "synoptic" device, or both; it does not have the real-time control function, but allows programming and display of all MECC ALTE DER2 functional parameters, via the USB port mounted on the board.
