Overview Technical Data

Servodrive for  DC motors.

Colibrì® is a compact bidirectional 4-quadrant analog servo drive designe for the control of DC motors with permante magnets up to 3.5Nm.

Managed by an input for speed or torque reference of the differential type +/- 10V, it is equipped with regulation for the acceleration and deceleration ramps. 

Colibrì® (CB) is available in two different variants to power motors with voltages between 20 and 110V d.c. and with 4 current sizes from 1A up to 10A nominal.

Two feedbacks are available, from Armature or from Tachometer Dynamo.
