is expanding its range of digital DC drives
up to 2250A (980kW/1320HP). All models ranging from 650-2250A are offered with two options - 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 suitable for controlling DC motors used in heavy industrial applications such as metal working, steel mills, mining or in the cement, rubber and plastics industries.
The optional top-entry or bottom-entry three-phase supply input makes 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 for use with 750V DC armature motors. Compared to the standard voltage this provides an increase in shaft power, up to 1500kW/2000HP for the 2250A model. That is 50 per cent more power delivered without an increased cable size.
Centre winding macros, spindle orientation and a fully controllable field enable users to control DC motors in a wide range of applications. The PLX is fully user-configurable 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 improves productivity by reducing downtime. A four-button keypad and large alphanumeric display make it easy to 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. Sprint Electric
offers a full range of PLX digital DC drives from 12-2250A, with all models available from stock. Whether for retrofitting or to use on 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.
