The new output filters from Schaffner, the model FN 510 series, reduce voltage slew rate (dV/dt) from inverter drives for variable speed motors.
High voltage slew rates can cause overstressing of long motor drive cables and cause insulation breakdowns in motor windings.
The Schaffner model FN 510 output filters are suitable for servo drives, closed loop vector drives and robotic applications and generally for both long and short drive cable setups.
The Schaffner model FN 510 output filters have low output impedance and are therefore ideally suited to fast and accurate dynamic changes typical of servo operations.
There are eight models in the series ranging in ratings from 1.5 to 30 kilowatt (4 to 66 ampere).
The Schaffner Model FN 510 output filters are characterised by low losses and are also protected against overload by a fan and internal temperature monitoring. The housing (IP20) and touch-safe terminals provide good equipment safety.
The Schaffner model FN 510 output filters are available from Westek Electronics .
