General information about the voltage regulator Mecc Alte DER1 AVR
Mecc Alte DER1 TTTT is a generator voltage regulator, designed to work independently and calibrated to maximize efficiency.
The regulator is designed to control many different types of generators so it must be properly configured for best performance. When the voltage regulator is turned on for the first time, there is a default setting configuration, which meets the characteristics and requirements of different installation conditions.
The DER1 is most popular Mecc Alte generator parts, available in 2 versions:
- DER1 can be used for Mecc Alte generators from 3 to 38: ECP3, ECP28, ECP32, ECP34, ECO38.
- DER1 is used to optimize and popularize Mecc Alte generators from 40 to 46: ECO40, ECO43, ECO46.
The two versions differ mainly in the default parameters of the regulator
