About the LA471171U540
The LA471171U540 is an Input Module (CS Module) from the AC890PX series of High Power Drives. The module and series were both manufactured by Parker and SSD Drives.
The LA471171U540 is a 3-phase input rectifier module that supplies DC power to the three CD Modules of the drive. This unit contains a half controlled diode/thyristor bridge.
The CS Modules have three protective features that are important to highlight. These units are protected against:
- Overvoltage
- Overtemperature
- Overcurrent
These protections are local, meaning they only cover the specific unit, and not the rest of the drive's modules.
