MEDIUMVOLTAGEAPPLICATIONS

MV APPLICATIONS

Configuration withstep-downstep-uptransformers• Standard LV inverters

STEP-DOWN STEP-UP

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

MV drive and MV motors for water industry

12-pulse supply

Power Supply Unit Modules

Power Supply Line

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.

MV APPLICATIONS

Configuration withMV Soft-Starter• No transformers needed
