More Standard FeaturesMeans better control of Centrifugal Pump applicationsThe global leader in products, technologies, and services for water andwastewater treatment, Siemens delivers the family of Strantrol IMPACTVariable Frequency Drives, designed specifically for centrifugal pumpsystems and applications. Using the latest IGBT technology, the VariableFrequency Drives are PWM drives loaded with features for variabletorque applications such as speed control on fans and pumps. Sincedrives are preconfigured with the correct parameters, startup, andcommissioning is faster, resulting in more cost-effective installations.Standard features that out powerthe competition• Built-in SWT P1 and JCI N2 (Metasys®)building automation system protocols foreasy network integration• Optional LON®, Modbus® and BACnet®(available 2006) interfaces• Unique low harmonics design minimizingthe need for external filtering• Built-in PID for fast accurate pressurecontrol• Pump controller staging/cascadingfor constant pressure, constant flowapplications• Multi-level program access• Loss of prime detection with or withoutan external sensor• Essential service mode for criticalapplications requiring continuous,uninterrupted operation• Accepts a wide variety of digital and analogI/O types, including direct Ni1000 sensorlevel inputs• One common interface throughout allpower ranges• Advanced Operator Panel (AOP) foruploading/downloading of parameters• Full form C relay contacts for digitaloutputsTotal Harmonic Distortion ReductionComparisonIn tests between a typical 6 pulse PWMdrive with and without line reactorsand DC link chokes versus the VFD,the Siemens IMPACT Motor Controllerdemonstrated superior harmonicperformance. In typical centrifugalpump applications, the VFD canreduce harmonics by up to 25%more than other VFDs, even with linereactors and DC link chokes.IMPACT MCLower harmonic design eliminatesproblemsThe generation of harmonic currents onthe AC line created by Variable FrequencyDrives can lead to problems and increasedinstallation costs. In addition, building designspecifications often require compliance withIEEE 519 standard which limits the amountof harmonic current and voltage distortionallowed on the power system. Other productssolve the problem by adding more equipment,more complexity and more cost.

The Siemens VFDs use a unique low harmonicdesign that eliminates the need for DC linkchokes and line reactors. In addition, Harmonee®software calculates the harmonicdistortions produced by the drive on your electricalsystem and compares them to IEEE standardsto ensure compliance. The result is reducedexpenses and the ability to use a smallerdrive. That adds up to dollars and sense.Complete offering, backed by SiemensSiemens offers the most complete line ofVariable Frequency Drives from a single source–UL/NEMA Type 1, 12, 3R, electronic bypassand conventional bypass options.
