The devices of the DCREG series, manufactured in Italy by Enertronica Santerno, are AC/DC converters implementing fully digital control system. The DCREG converters fit:▪ the armature and field supply of direct current motors to enable the speed or torque control.The DCREG4 operates in four quadrants, while the DCREG2 operates in two quadrants.▪ The DCREG devices can be used to supply and regulate voltage for very inductive loads, such aselectromagnets.HIGHLIGHTS▪ Product ratings ranging from 10A to 4500A (2.4 kW ~ 3200kW)▪ Wide range of supply voltage levels, from 200VAC to 690VAC, 3ph, 50-60Hz▪ DCREG2: Unidirectional, regenerative, 2-quadrant▪ DCREG4: Bidirectional, regenerative, 4-quadrant▪ Easy commissioning thanks to:o Self-calibration of current and speedo Self-calibration of fieldo Insensitivity to phase sequence▪ Overload up to 150% In for 60s▪ Field regulator, economy and field boost functionality▪ Predictive control, increases the dynamic response of the motor▪ Feedback from tacho generator, from encoder and armature▪ Automatic switching of the armature feedback in the event of breakdown oftachometer/encoder (safer operation)▪ Integrated control for magnet feeding applications▪ Control of step current limit or hyperbolic current limit▪ High accuracy level of ± 0.1% of rated speed following:o Load variations up to 100% of the rated torque.o Root mean square variations of the supply voltage of +10/-15% (or higher, depending oneach case) with respect to the rated value.o Temperature variations of ±10°C.▪ Integrated multimeter▪ Speed multiramps, “S” ramps, double speed loop regulator, JOG Control, 7 programmablespeed levels▪ RS485 serial communication interface (optional)▪ Degree of protection: IP00 (IP20 with optional protections)▪ In compliance with EMC EN61800-3/IEC1800-3 second environment (industrial environment)with no auxiliary filters.▪ Global standard compliance: CE, UL (up to DCREGX.350 model ), EAC▪ Thorough manufacture with first class materials, fully Made in Italy
