General specifications
Electric device
The electric device is a heavy-duty converter designed especially for electric or hybrid drive trains for
mobile work machines, buses or marine vessels. Depending on the options selected, it can act as a motor
inverter (+MC option), active front end (+AFE option) or it can create a microgrid (+UG option).
The advantages and features of the electric device:
•
Extremely compact structure, weight only 14 kg.
•
Robust design withstanding high levels of mechanical vibrations and shocks.
•
High protection class IP67 ensuring operation in extreme conditions.
•
Wide ambient operating temperature range from -40°C...+85°C.
•
Liquid cooling.
•
Wide allowed coolant temperature range.
•
Multiple mounting possibilities.
•
Designed especially for highly cyclical loads typical in heavy mobile work machines.
•
Controls both induction and permanent magnet motors with or without sensor.
•
Speed and torque reference motor control.
•
Generator control mode for DC-link voltage control.
•
Flexible control interface –CAN, resolver, analog, digital inputs/outputs.
•
PowerUSER PC-program for commissioning available.
•
Various communication protocols, for example CANopen, SAE J-1939.
•
High performance vector control.
•
Wide selection of protective safety functions.
These electric devices are designed for variety of applications:
•
Converting alternating current (AC) from electrical generator to direct current (+MC option) for
energy storage
•
Active Front End for connecting to AC grid with regenerative power and low harmonic. (+AFE option)
•
Creating standalone microgrid (+UG option)
Note that +AFE and +UG options require an external LCL-filter unit or a transformer and LC-filter
combination.
