The DER1 is an AVR (Automatic Voltage Regulator) used on Meccalte AC alternators. It has different pots such as “VOLT” for voltage adjustments, “STAB” for stability adjustments, “HZ” for underfrequency threshold calibration and “AMP” for excitation overcurrent threshold calibration. The DER1 is set with factory settings and it needs adjusting in order to meet your diesel generator specification.
