MEDIUM VOLTAGE APPLICATIONS

Configuration with step-down step-up transformers MV APPLICATIONS Standard LV inverters 2

Main features: STEP-DOWN STEP-UP Frequency converter for motors - 30...3.000 kW, 1 kV ÷ 15 kV via step up trafo - square torque applications Maximum losses at full load - Inverter: 60 kW - Filter: 6 kW Fundamental wave content of output voltage: 95% THD < 12% Reduced level of harmonics on the AC mains 3

MV drive and MV motors for water industry 4

12-pulse supply MV/LV Power Supply Line 12-phase transformer with Power Supply Unit Modules Power Supply Line MV/LV Power Supply Line 12-phase transformer with 30°- phase shifted outputs This kind of connection and installation allows reducing the harmonic currents that are generated on the power supply line. Capacitors have longer life because the ripple applied goes from 300Hz to 50Hz of the mains power supply at 600Hz. 5

Configuration with MV Soft-Starter MV APPLICATIONS No transformers needed 6
