Mk Electric TV Guard + Free HP 1.5M HDMI Cable

Low power (under-voltage) will certainly damage any appliances . The TV 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.

Automated functionalityThe TV 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.
Dial ControlsThe MK volt guard allows you to control how sensitive the guard is to voltage problems. Using the control dial you can set the desired level of protection and specifications.
