DC Drives And Motor Control

Sprint PL/X Drives

The Sprint PL and PLX series DC Drive is a fully digital DC drive system providing 5kW – 980kW output power. Available in 2Q (single direction) and 4Q (fully regenerative) variants, the range comprises 5 compact chassis sizes with models rated from 12A to 2250A output current. The Sprint PL or Sprint PLX boasts an extremely versatile operating input voltage range of 12V – 500VAC as standard. Options are available for 600V and 690VAC input.

The Sprint PL/X boasts the best power density from any comparable DC Drive on the market. All models include a 40-character alphanumeric backlit display that makes it easier to quickly navigate through an extensive range of software functions.

Sprint SL/X Drives

The Sprint SL and SLX range provides 2Q / 4Q operation across 11 models from 5kW – 145kW output power.

The 4Q models improve your energy efficiency by regenerating energy into the mains supply whilst under braking. The energy invested in accelerating the load mass is recovered when braking. No dissipation of energy in wasteful braking resistors. With fully isolated control electronics and a wealth of I/O, the Sprint SL/X is easy for you to integrate with other drives and equipment. The SL/X has a built-in field weakener for extended speed range to allow you greater control of high motor speed applications.

Sprint SLE Drives

The Sprint SLE Series comprises a range of analogue 2Q / 4Q DC Drives delivering output current up to 330A to control motors up to 145kW.

For users who prefer or require analogue control loops, the SLE Series provides an economical, compact and reliable control platform. The Sprint SLE drive has been specifically designed at a cost and size to benefit OEMs without any compromise in specification, reliability or performance.

Its compact footprint (250mm x 204mm) enables additional savings and ensures easy integration within new designs or trouble-free installation when retrofitting

Sprint PL/XD Drives

The Sprint PLXD is designed to be used with external thyristor stacks usually of high power. The unit comes with all the features of the PLX range and the same menu driven system. The Sprint PLXD can cope with armature voltages up to 1000 VDC and can be calibrated to suit the users CT's with the facility to be set to 30,000 Amps using the correct current transformer ratios and resistor burden values.

The field as standard can drive up to 50 Amps and is taken from the EL1, EL2, EL3 supply located at the top of the unit. The final correct field current or voltage for the DC motor is determined by the menu calibration settings.

This is a compact unit that makes it easy to install next to the main thyristor stack thus helping to keep cable runs to a minimum.
