Product Description

AVR DER DER1 Automatic Voltage Regulator for Generator Alternator Genset Volt Regulation

The DER AVR is a voltage regulator for synchronous alternators, designed for stand alone working and calibration; to maximize performances, the regulator should be intended as part of a system made up of at least three components: the AVR DER1 Voltage Regulator (control unit), a communications module (USB2DxR, for example) and a supervision unit, as illustrated in figure 6.

DER Series AVR have Two versions of the DER 1 and DER 1/A available; DER1 AVR is optimised for Series 3 to 38 alternators, DER1/A AVR is optimised for series 40, 43 and 46 alternators; the two versions differ primarily in the default parameters. NOTE: the parameter that defines the output voltage (with the VOLT trimmer disabled) is set on 0 (so that the adjustment takes place on the minimum voltage).
