Ang GEYA GRV8-1UVR mao ang single-phase undervoltage relay nga specifically designed para sa industrial ug commercial applications. Ginabuhat niini ang proteksyon sa inductive loads sama sa air conditioning systems ug motors gikan sa damage resulta sa sudden low voltage fluctuations. Gigamit niini ang advanced True RMS measurement technology, nagmonitor niini sa supply voltage sa real time ug maong disconnects ang load kon ang voltage mobaba sa preset threshold, effective sa prevention sa equipment damage ug production interruptions.
