The active and reactive combined transducer is an integrated measurement device that can monitor the active and reactive power in the power system at the same time and provide comprehensive power parameter data. The active and reactive combined transducer can reduce the installation space and wiring complexity, and reduce the cost of multi-sensor deployment. The active and reactive combined transducer is calculated based on the voltage and current signals at the same time to avoid errors caused by time differences.

Wiring

Tips: Advantages of active and reactive combined power transducer

Save space and cost: Measure active and reactive power simultaneously with a single device, reducing the need to install multiple independent transducers, hardware costs and wiring complexity. Suitable for scenarios with limited space (such as distribution cabinets, and compact equipment).
High data synchronization: Calculate active and reactive power based on voltage and current signals at the same time point, avoiding data asynchrony caused by the sampling time difference of split sensors.
Easy maintenance: Only a single device needs to be calibrated, reducing the workload of calibrating split transducers one by one. The centralized design facilitates monitoring and diagnosis, reducing maintenance difficulty.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
