DC and slip ring drives
DC and slip ring drives from a number of manufacturers are available from Westin Drives. We can supply a wide range of single phase and two and four quadrant analogue and digital DC products for controlling DC motors up to 2250 Amps.
Products include 0.55kW to 980kW single and three-phase DC drives and 2Q and 4Q DC motor controllers in analogue or digital models. They are available with DIN Rail mounting, panel mounting or in metal enclosures. We stock a complete range of auxiliary equipment including fuses, holders, line reactors and filters. |
Slip ring drives
We supply Slip Ring Drives from 75 - 800 kW for integration into your existing systems or for new applications. The JL/X range of slip ring motor drives from Sprint Electric is a derivation of the PL/X Digital DC drive product range. It shares the same software and hardware platforms and delivers the same precise digital control functionality enjoyed by users of the established range of DC Drives.
The main difference between the PL/X and JL/X range is that the thyristor stack configuration has been designed to provide a firing angle controlled three-phase output (U, V, W) suitable for controlling slip ring motors in either two or four-Quadrant modes. All the fieldbus options and configuration software packages used with the PL/X are also available for the JL/X range.
The JL/X range covers output currents from 100 to 1680 Amps and is available in three frame sizes with standard supply voltage inputs up to 480VAC. (Frame two, four and five). Frame four and five also have the option of being supplied as HV units that are able to accept AC supply voltages up to 690 VAC for higher voltage applications.
All models have the high current three-phase supply terminals in standard top entry, with the motor connections at the bottom of the unit. A complete range of auxiliary equipment is available including fuses, holders, line reactors and filters.
