Sprint Electric has increased its range of digital DC drives up to 2,250 Amps (980kW). All models ranging from 650 to 2250 Amps are offered with two options: Either top entry or bottom entry three phase supply input, and as high voltage (690V ac) or standard voltage (480V ac) models. Available as two quadrant or regenerative four quadrant types, these digital DC drives are ideal for controlling DC motors used in heavy industry applications such as metal working, steel mills, mining, or the cement, rubber and plastics industries.The optional top entry or bottom entry three phase supply input make it easier to install the high power DC drives by giving engineers a choice. For retrofit installations the two options make it easier to use the application's existing cabling; engineers can save time and money by using whichever supply input option is more suitable for their cabling arrangements, instead of adding more expensive copper cable. In new designs, the engineer has the choice of wiring options, which can save money and space when designing new control panels.All models are also offered with a high voltage supply option of 690V ac supplies for use with 750V dc armature motors. Compared to the standard voltage this provides an increase in shaft power, up to 1,500kW for the 2,250A model. That is 50 percent more power delivered without an increased cable size.Centre winding macros, spindle orientation and a fully controllable field allow the user to control dc motors in a wide range of applications. The PLX is fully configurable by the user and comes equipped, as standard, with a comprehensive suite of application blocks. A configuration checker quickly detects any conflicts in the configurations generated by the user. And the extensive range of motor protection features improve productivity by reducing downtime. A four button keypad and large alpha-numeric display make it easy to quickly navigate through an extensive range of software functions. The PLX has a number of fieldbus communications options, including: Profibus, DeviceNet, CC-Link, EtherNet/IP, Modbus and CANopen.Increase in accuracy and productivity, and lower energy consumption make dc drives from Sprint Electric ideal for retrofits when a more effective, modern drive system is required. Sprint Electric offers a full range of PLX digital dc drives from 12A up to 2,250A, with all models available from stock. Whether in retrofits or original equipment, dc Drives from Sprint Electric are being used in many different applications including metal processing, the pulp and paper industry, rubber and plastic processing, lifting equipment, food processing, leisure industries and many more.
