Low power (under-voltage) will certainly damage any refrigeration applianceâs compressor. The Mk Tv and 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 reduce 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.
