Low power (under-voltage) will certainly damage any refrigeration appliance’s compressor. The Amaze Fridge Guard protects your appliance by disconnecting the power when it goes below unacceptable level. 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 is it subjected to a massive surge normally experienced when power returns after power cuts. Order it online from VICMER STORE and have it delivered to you wherever you may be. The Fridge guard will disconnect the power to your appliance if the mains voltage drops below or above a pre-set limit. It will also will re-connect automatically only after the supply has returned to acceptable limits after a 3 minute wait time.
