Low power (under-voltage) will certainly damage any refrigeration applianceâs compressor. The Mk Tv and fridge guard protect your appliance by disconnecting the power when it goes below an unacceptable level. Additionally, there is a delay when power returns to normal this reduces the chances of fridge and TV being damaged due to excess power flow. 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.
