Drives for DC motors, applications with electromagnets and other DC loads
– Two-quadrant DCREG2
– Four-quadrant DCREG4
The DCREG devices are fully digital control AC/DC converters supplying DC motors armature circuit and field circuit to obtain speed control or torque control, featuring 4-quadrant operation for DCREG4, or 2-quadrant operation for DCREG2.
Te DCREG, the thyristor converter by Santerno, may be used to power supply high inductive loads, such as electromagnets. The application issues due to this type of load have been fixed by a control algorithm specifically developed for DCREG4 converters
