MECC ALTE DER1 AUTOMATIC DIGITAL VOLTAGE REGULATOR

MECC ALTE DER1 AUTOMATIC DIGITAL VOLTAGE REGULATOR

Regulator Mecc Alte DER1 fully digital voltage-controlled for synchronous alternators, prepared for stand-alone operation and calibration.

Born as an evolution of the Mecc Alte DSR, it has expanded its functions by adding three-phase/single-phase sensing with automatic setting, greater flexibility and greater flexibility. in remote input from parallel controllers, soft start routines and a voltage accuracy of 0.5% in static conditions.

The connectors for the connections to and from the electric generator and the communication module are located on the DER1 regulator. The unit is of supervision can be be made up of a personal computer, another “synoptic” device, or both; it does not have the real-time function, but allows the programming and display of all the functional parameters of the DER1.

Since it is designed to control many types of generator, the regulator must be suitably configured to obtain the best performance; the settings are mostly stored in an integrated non-volatile memory (EEPROM).
