  1. MEDIUM VOLTAGE APPLICATIONS

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

  3. STEP-DOWN STEP-UP Main features: 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

  4. MV drive and MV motors for water industry

  5. Power Supply Unit Modules Power Supply Line 12-pulse supply 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.

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

  7. ASAMV Main features: - Power supply from 2300Vac to 15000Vac, rated current from 200 to 600A - 3 types of motor starting (Constant Current, Current Ramp, Torque Control) - Stopping (Soft Stop, Pump control profi les, Auto Stop) - Allowed overload to 600% of the nominal current - CABINET MODEL IP54 protection degree Class A EMC - Operating temperature from 0 to +50°C (option from -20 to +50°C) - Protection: Under/ Overvoltage, Supply Frequency, Phase Sequence, Shorted SCR, Motor Overload (Thermal Model), Instantaneous Overcurrent, Undercurrent, Current Imbalance, Excess Start Time, Power Circuit, Auxiliary Trip
