The ODX-3000 series inverters from Premium provide a three-phase sinusoidal voltage output waveform that is suitable for motors and does not cause the same stress on motor windings that square wave output inverters can create, according to the company.
The output frequency can be selected to be either 50 or 60 Hz via a DIP switch, making it suitable for use with either 50 or 60 Hz motors. The inverter also has a soft start function where during start-up the output voltage rises linearly from zero to nominal voltage, which helps reduce voltage dips on the network as well as producing less mechanical shock to the motor and equipment coupled to it.
The inverter gives the user the ability to monitor the status of the input and output voltages via two separate solid-state relays and with the ability to both set and monitor parameters via RS232.
Railway and industrial versions are available. The railway version has been designed to the standards specified in EN50155.
