Based on a new "C-Light 4 Quadrant" technology, the variable speed drive POWERDRIVE FX offers an ultra compact regenerative solution. Thanks to a new generation of controls, POWERDRIVE FX provides a performant sensorless Permanent Magnet motor mode.

POWERDRIVE FX

Safe Torque Off inputs: disable drive by 2 separate channel logic (SIL3 - PLe)Security mode: protections disabled to force the drive to run (smoke extraction, fire mode)Diagnostic

- Timestamping of last 10 trips - Memorization of events preceding a trip

Integrated safety functions ..........

Dynamic braking: naturally regenerative rectifier (patented)No braking resistorBetter efficiency than a common structurePOWERDRIVE FX THDI better than IEC 61000-3-12 standard and independant of the loadSize reduction of components on the power supply side (transformer, disconnect switch, cables…) due to an improved form factorNo overvoltage on motor terminals due to stabilized DC bus Less losses: low value line reactor, film technology capacitors...
