Sprint SL DC Drives
Sprint Electric SL Series - 2 Quadrant Non-Regenerative Analogue DC Thyristor Drive for 200 to 480v Supply Typical Motor output for motor speed and torque control.
The Sprint SL 2 Quadrant and models are compact, reliable and efficient DC motor controllers. With fully isolated control electronics and a wealth of I/O, the Sprint SL are easy for you to integrate with other drives and equipment. To allow you greater control of high motor speed applications, the SL also has a built-in field weakener for extended speed range.
Details & Features
Why use a Sprint PL Series Inverter?
The Sprint SL drive series have multiple outstanding features including: Multiple inputs and outputs, ultra stable potentiometer reference for optimum long term speed and torque stability
Simple but Powerful
Sprint SL Series drives come with torque control input for basic winding or tension control, overspeed limiting, numerous alarms for enhanced drive, motor protection and configurable field bridge for easy motor field voltage matching.
Configurable & Intelligent
The motor and drive are protected by a stall timer which automatically removes power after 30 seconds if the required speed cannot be achieved. The drives will provide up to 150% of the preset maximum current for up to 30 seconds allowing high short term torques during acceleration or other changes in load. lndependant control of either the current or speed loops by external inputs allows torque or speed control applications with overspeed or overcurrent protection. The demand signal may be derived from a potentiometer, 0-1 0V signal or 4-20mA loop. The speed feedback signal may be selected to be the ARMATURE VOLTAGE or a shaft mounted TACHOMETER.
The 4Q models improve your energy efficiency by regenerating energy into the mains supply whilst under braking. The energy invested 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 SL is easy for you to integrate with other drives and equipment. The SL has a built-in field weakener for extended speed range to allow you greater control of high motor speed applications.
Other features include: 2 and 4 Quadrant versions available. Available from 5KW to 145KW, extra 50% peak torque for rapid acceleration or shock loads. Zero reference interlock facility ideal for extruder applications, numerous alarms for enhanced drive and motor protection. Torque control input for basic winding or tension control, with overspeed limiting, and output signals for easy display of motor speed and load.
