The POWER-Analyzer LK601 was specially designed for use in electrical drive test benches. It helps to simplify development, analysis and EOL-Testing. Intuitive, precise and future-proof!
With the POWER-Analyzer LK601 up to 6 electrical phases (U+I) can be recorded and analyzed simultaneously at high precision. With an off-the-shelf equipped CAN interface our power meter can also record torque, speed, temperature and other important process parameters. Using the intuitive and customizable POWERStudio-Software, all settings can be setup on the computer and user-defined parameters / views can be created.
Key component of our measuring device is an UX-friendly PC-Software. All settings can here be made, measurements can be started, analyzed and monitored. The simple way of saving settings and data enables reliable reiterations of measurement sequences.
The analog and digital technology (of the sensing modules) record current and voltage with the highest accuracy. Thanks to the high bandwidth and sampling resolution, high-frequency components can also be precisely analyzed. Short signal latency guarantees the best synchronicity. Specially at high reactive power.
Designed for modularity right from the beginning, the LK601 power meter is future-proof in terms of expandability and flexibility. Modifications to the hardware and / or software can be used to react quickly and easily to changed requirements. Always stay up-to-date!
Current power analyzers are often based on oscilloscopes and offer only a few innovations in terms of handling, flexibility and expandability. Many devices just provide usual input terminals and simple ways of displaying measured data.
Those devices, which are mostly designed for compactness, are equipped with small displays and complex user interfaces through which almost all settings and analysis steps must be carried out. If software required for more detailed investigations is offered, it is often bulky and inflexible to use. Moreover the recorded data first has to be manually exported from the power analyzer and imported into an other data manipulation software.
If synchronous recordings of physical measured values such as temperature and vibration are required, the use of an additional expensive data logger may also be necessary.
Innovative ideas often arise from a personal need. If available products do not cover the own applications, requirements and framework conditions, you have to tackle it yourself. That's what we did!
Originally developed for our own test benches, the LK601 power meter now also offers other customers decisive advantages. We focused on a fluid and simple handling, customer and application-oriented flexibility and future-proof expandability. Deliberately we avoided using unnecessarily costly modules and additional, confusing, device-internal input and visualization elements.
The result is the MATUSCHEK electrical POWER-Analyzer LK601, which delivers high-precision, repetitious measurement results, is easy to use and has powerful analysis tools. Our 30 years of experience as a supplier in the field of high-quality measurement technology for the automotive and electrical industry helped us to develop a high quality product.
Drive systems with electric motors can be constructed from a large number of components which need to be tested. Front and / or rear drive, wheel hub motors, inverters, gearboxes, cooling systems, battery modules and other modules. The possibility of expanding and adapting the corresponding test system is therefore essential.
The flexible configurable basic device of the POWER-Analyzer enables extensive expansion options for your test equipment via different expansion cards and an integrated CAN interface. Whether for electrical, mechanical, thermal or other measured variables, a power analyzer that can do more!

With an electric power meter, the electrical energy or power of electrical consumers such as motors can be measured. The performance is given in watts. The measured values collected in the device can be transferred and evaluated to the PC if desired.
In general it needs to be distinguished between DC (Direct Current) and AC (Alternating Current) measurements. While first mentioned may also be well recorded by many standard devices, an AC measurement has higher requirements for the measuring system. Here, the exact detection of the signal frequency and phase position of current and voltage signal is essential.
The active power P is the part which converts into another energy form (mechanically, thermally or chemical). It is thus the crucial measured variable for efficiency determination and energy balance. DC power is always pure active power.
While a DC power is always the active power P, with an AC system, the possible phase shift of current and voltage leads to a so-called reactive power Q. The reactive power does not lead to a power or drain, but is retained to the energy system. Nevertheless, this power amount must be provided, which must be considered when designing a drive system. The resulting apparent power S is then defined as follows:
If the system is excited by sinusoidal means, results for the active and reactive power::
Both for the determination of the signal frequency and when measuring systems with a small power factor , the use of a precision power analyzer such as, for example, the POWER-Analyzer LK601 is indignant.
