Reactive power compensator 20 kVAr, 400 V, 3-phase, 4-wire wall-mounted, with a 4.3-inch screen and WiFi module, with a glued back cover.

The modular reactive power compensator SVG KE-SVG4-20/0.4B with a power rating of 20 kVAr is designed for dynamic compensation of inductive and capacitive reactive power in three-phase low-voltage networks of 400 V. The device, utilizing IGBT transistor technology and an advanced DSP processor, responds to changes in the power factor in less than 10 ms, allowing for the maintenance of the set cosφ and the elimination of penalties for reactive power consumption.

The KE-SVG4-20/0.4B compensator is equipped with a 4.3 inch color LCD display with a touch interface, a WiFi module enabling remote monitoring via a browser, and an RS485 interface. The device operates in a 3P4W (4-wire) network, and it is possible to connect up to 8 modules in parallel. The bonded rear cover (B) ensures the enclosure's tightness when mounted on the wall. The manufacturer's warranty is 24 months, extendable to 48 months.
