What kind of domestic regulators more safety?

Domestic regulators and industry regulators are differentiated, for example Gechy Electric domestic regulators with additional high-voltage protection function, primarily to elimination by the regulator resulting in damage to the appliance and cause eliminating fire.

Sent to the appliance's voltage above 250V, it will pretty dangerous, internal components will overheat or burn, which may eventually cause home fires, electrical leakage. In both cases, the regulator output high voltage, one is the mains voltage is too high exceed of stability range; thg other is the regulator itself fails, sometimes neither control voltage, but also the voltage increases. If the regulator without high voltage protection, it will add to household appliances.

Without the protection of high-voltage regulator is not acceptable!

Gechy Electric regulator set computer delays, accurate and reliable elimination of internal injury resulting from delay to fridge/freezer. Like fridge or freezers this type of compressor appliances, in the middle of two power outage time, if less than 3 minutes, the compressor starts will be very difficult & easy thermal injury, over time which causes the damage. So if regulators delay time less than 3 minutes, refrigerators, freezers will bring "internal injury."
