Low power (under-voltage) will damage any refrigeration appliance’s compressor and High Power (Over voltage) will damage any electrical or electronic equipment. The AVS30 is the most complete power protection device combining over-voltage, under-voltage, power-back surges and spikes/surge protection. Additionally, there is a delay when power returns to normal. This will ensure that the appliance is not switched on-off repeatedly during fluctuations nor it is subjected to a massive surge normally experienced when power returns after power cuts. Also accommodating a start up / inrush current of 110Amps. Voltage protectors are used when voltage current surges beyond rated value. These units quickly cut power to avoid damage or even fire within your refrigerators, air conditioners, heaters, coolers, freezers, etc. 

Voltage protectors feature: bright LED lighting, easy installation, single output, and cutoffs of under voltage .
