Good friends recently acquired a voltage regulator of the brand forza model FVR-1211USB, my doubt arises at the moment when the led boost that makes a sound inside the regulator like a relay is turned on and apparently the voltage rises and then the voltage goes off Frequently up and down connect my fan to the outlet and I can see how the voltage suddenly increases but it is not constant, I would like to know if that is normal in the regulator or is having problems? I bought the protector to avoid damage to my TV and other electronic devices and these changes make me doubt should I change it? will it be damaged? I appreciate your response!
