The input, output, power supply and shell of the reactive power transducer are isolated from each other, which can prevent high-voltage signals from harming equipment and personnel. The compressive strength of the reactive power sensor is AC2Kvrms/min, and the insulation resistance is greater than 100 MΩ at DC 500V. It uses a 35mm standard rail or is fixed on a cabinet. The reactive power transducer has good quality and is easy to install.

Tips: Active Power Transducers vs. Reactive Power Transducers

Measurement Purpose: Active power transducers measure active power (W/kW) that performs actual work. Reactive power transducers measure reactive power (VAR/kVAR) that affects power quality but does no useful work.
Application Focus: Choose active power transducers for energy monitoring, efficiency analysis, and load management. Use reactive power sensing for power factor correction and reactive power compensation.
Load Type: Active power dominates in resistive loads (heaters, incandescent lamps). Reactive power is present in inductive/capacitive loads (motors, transformers, fluorescent lamps).
Power Factor Impact: The higher the active power, the higher the efficiency. Excessive reactive power results in lower power factor, resulting in wasted energy and higher costs.

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.
