Five fully-controlled two-quadrant

Range:

• Output powers from10 to 115KW, 400V.
• Output current: up to 250A.

Features:

• Compact controllers with isolated heat sink.
• High response thanks to six-pulse three-phase bridge and leakage current adaptation.
• 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.
• Mains connection independent of the phase sequence.
• 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
• Current limitation from 0 to Max output current.
• Ambient Temperature: 0- 45°C.

Inputs and Outputs:

• 1 start/stop digital input.
• 1 speed reference analogue input 0-10V.
• 1 additional speed analogue input from -10 to +10V.
• 1 torque controller analogue input from 0 to -10V
• 1 tacho feedback input 10-180V.
• 1 analogue output corresponding to the output speed.
• 1 analogue output corresponding to the actual armature current.

Option board can be retrofitted:

• Set-value integrator 2003
• Winding calculator 1071
