European SSD full digital DC governor
Continental SSD full digital DC governor 590C/591C
590C digital DC converter, sub-590C, 591C series, 590C for 4Q controller, 591C for 2Q controller. 4Q DC controller, which is a four-quadrant DC controller, can be used for regenerative braking in function; 2Q DC controller is a two-quadrant DC controller with no regenerative braking function
The governor uses a three-phase power supply of 110V to 500V to provide DC output voltage and current for armature and excitation. It is suitable for control of various shunt, overexcitation and permanent magnet DC motors.
3 phase, 45Hz-65Hz, 110V-480V+10%, 660V single phase, 45Hz- 658Hz, 110V-220V+10%
Cooling method: natural cooling, built-in fan cooling, separate fan cooling
The power circuit is completely isolated, greatly improving operational safety and simplifying wiring between the system's internal controls. Control function: 16-bit microprocessor realizes full digital control, advanced PI (proportional-integral) adjustment, adaptive current loop to achieve good dynamic performance, current loop has self-tuning function. Adjustable PI speed loop with integral separation. Speed control: armature voltage feedback (with IR compensation); encoder feedback and analog tachogenerator. Speed range: feedback with tachogenerator, the speed ratio is 100:1. Steady-state accuracy: encoder feedback with speed setpoint (serial line or P3) is 0.01%; analog speed feedback is 0.1%; armature voltage feedback is 2%; can be achieved with QUADRALOCMKII digital controller Fully accurate (0.0% error). Parameters: All parameters are adjusted by software through the serial port or the buttons on the panel and the LCD display. Diagnostics: Fully computerized, latched fault, automatic display. Digital LCD monitor monitoring. All diagnostic information is available via RS422/RS485 . LED circuit status display.
