Three phase line reactor

AC line reactors are added to the input of the drive and placed in series with the incoming line. They help to mitigate harmonics and because they are between the line and the drive, they are able to act as a buffer for surges and other transients. The intended purpose of a line reactor is not to offer high levels of surge protection and, if greater protection is desired, a dedicated protective device is a much better solution.

Passive Filter

FN 3416 (50 Hz) models of the ECOsine product family represent the very compact “economy line” with a THID performance of ≤10 % (with Ldc). They are ideal for non-linear three-phase equipment with B6 rectifier front-end that do not require the industry leading <5 % THID performance provided by Schaffner ECOsine.

Enclosed High Power Filter

Schaffner ECOsine filter cabinets (Filters for diode rectifiers) can be applied to virtually any kind of power electronics with front-end six-pulse rectifiers, where harmonic current distortion needs to be reduced to defined limits. The compact filter cabinets can be easily commissioned and quickly installed into extisting designs without requiring an in-depth system analysis or highly trained specialists.

High Power Filter

Schaffner ECOsine filter cabinets (Filters for diode rectifiers) can be applied to virtually any kind of power electronics with front-end six-pulse rectifiers, where harmonic current distortion needs to be reduced to defined limits. The high power filter modules are particularly suitable when no room for packaged filters is available. The Schaffner solution can conveniently be incorporated into cabinets, which allow the filter components to be wired along with the overall electrical wiring job and to be cooled by jointly utilizing the overall cooling concept.

Selectable AC transducer

TAS-321DG is a micro-controller based AC transducer with 1 analogue output for measurement of bi-directional current. The sign for current direction is based on the measured power direction. Furthermore, the transducer can be used for measurement of active power or reactive power on a 3-phase network where only 2 phases are available for the measurement. TAS-321DG can be delivered pre-configured or it can be delivered un-configured for customer configuration through the PC interface.

AC voltage single function transducer

The voltage transducers type TAV-311DG or TAV-321DG are transducers for measurement of a sinusoidal AC voltage converted into a DC current or DC voltage signal proportional to the measured value on a single phase or 3-phase network. PLCs, PCs, microprocessor control, indicators, alarm units etc. can be operated by the output signal.

Multi-transducer

The MTR-3 is intended for measuring and monitoring single-phase or three-phase electrical power network. The MTR-3 measures RMS value by means of fast sampling of voltage and current signals, which makes the instrument suitable for acquisition of transient events. A built-in microcontroller calculates measurements (voltage, current, frequency, energy, power, power factor, THD phase angles, etc.) from the measured signals.
