Delta Electronics C-2000 series variable speed drives

The Delta Electronics C-2000 series variable speed drives provide a high-performance solution to three-phase motor speed control.

The C-2000 uses field-oriented control to fulfil the demands of high starting torque, accurate speed and torque control. The drive can be operated in open or closed loop vector mode and speed, torque or position control mode. In closed loop torque control mode the product can provide up to 150% torque at zero speed for crane and lifting applications.

Available in power ratings from 0.75 to 355 kW, features include speed/torque/position control mode, dual rating design (CT or VT), four-quadrant torque control, built-in PLC, built-in brake unit, built DC reactor and a range of extension cars for I/O, encoder feedback and fieldbus modules. 

Models up to 30 kW (37 kW VT) include a built-in EMI filter to meet CE and C-tick EMC standards. A large LCD display and keypad allows for easy programming and clear information display with graphics capability. The removable keypad can also be installed with the use of an optional adapter in the door of the cabinet to provide an iP56 control and display unit.

Fieldbus modules include Profibus, Devicenet, Modbus TCP and Ethernet/iP with CANopen and Modbus already built in. A dedicated variable torque  version for fan/pump drives, the product includes additional features specifically suited to HVAC applications, such as the built-in BACNet, ‘fire mode’ and multipump operation.

The mechanical design provides good heat dissipation and coated circuit boards for use in harsh environments.
