Ang GEYA GRV8-1UVR ay isang single-phase undervoltage relay na espesyal na disenyo para sa industriyal at komersyal na aplikasyon. Ito ay naka-udyok upang maprotektahan ang mga inductive loads, tulad ng air conditioning systems at motors, mula sa pinsala dahil sa biglaang pagbabago ng mababang voltaje. Gamit ang advanced True RMS measurement technology, ang device na ito ay patuloy na nagmomonitor ng supply voltage sa real time at agad na nagdidisconnect ng load kapag ang voltaje ay bumaba sa isang preset threshold, na nagpapahintulot ng mabuting pagsasanggalang laban sa pinsala ng equipment at production interruptions.
