MD880 High Performance MultiDrive MD880 — INOVANCE

MD880MD880 Series High Performance Engineering Converter (Single Drive MD880-01S / Multi Drive MD880-20/30/40/50)

MD880 High Performance MultiDrive INOVANCE

Engineering drive platform for heavy-duty applications in two topologies: MD880-01S single drive 5.5–450 kW and a common-DC-bus multidrive of 3.7–5,600 kW with basic 6/12-pulse, regenerative or active front-end rectifier (THDi < 5 %). Voltage classes 380–415 V and 525–690 V, light-duty 110 % and heavy-duty 150 % overload for 1 min in 5. FVC with ±0.01 % accuracy and 1:1000 range, torque response ≤ 5 ms, starting torque 200 % at 0 Hz. HCU controller with plug-in SD card and three slots (encoders, I/O, fieldbuses), black box for 50 faults, parallel operation of up to 10 modules.
