NORD Drive Systems has extended its SK 200E family of decentralised drive solutions with a new size 4 inverter with a rated power output from 11 to 22 kW.
The self-cooling inverters are available for motor-mounting or with a wall mounting kit, and the IP55 housing provides protection from dust and water jets. Models feature sensor-less current vector control, an integrated brake chopper, a control module for an electromagnetic brake, and the safety function ‘Safe Torque Off’.
User programming and operation of this distributed inverter range is with a choice of control boxes or via the free-of-charge NORDCON software. Common applications can be quickly selected via DIP switches.
An analog input allows for variable speed adjustment of an SK 200E pump drive, and if a pressure or flow sensor is connected to the second analog input, the SK 200E can actively and autonomously control process values.
During partial load operation, an integrated energy saving function kicks in to ensure environmental friendliness. Power electronics integrated in the motor or mounted nearby can effect considerable savings by eliminating long shielded motor cables, output filters and chokes.
