This 472 E1 (Lenze) drive is at your disposal to replace your defective equipment and has a guarantee adapted to your needs.
The 470 series of controllers comprises three single quadrant controllers with output powers from 1.3 kW to 7 kW. The most important features include:
• Compact controllers with isolated heatsink
• Operation with tacho or armature voltage feedback with "I x R compensation"
• Isolation of control electronics and power stage when tacho feedback is used
• Self-synchronization of the phase shifter for 50 ... 60-Hz mains
• High interference margin due to integrated synchronizing filter
• Burst-gate thyristor control in the power stage
• Reliable operation also for mains voltage fluctuations and short-term mains failures due to static and dynamic voltage monitoring
• Display of the operating states using LEDs
• Free connections for set-value delay, actual value differential component, speed reset time
• Option board can be retrofitted:
− Set-value integrator 2003
− Winding calculator 1071
• Compliance with the CE directives for the erection of a CE conform drive system
The controllers of the types 47x are electrical equipment for the installation into control cabinets of electrical systems or machinery.
• The controllers of the types 47x are designed as components for the control of speed-variable drives with separately-excited DC motors or for the assembly with other components to form a machine or system.
