Automatic Induction Protection: Protect your electrical devices by interrupting the current flow from voltage spikes, instant surge, voltage fluctuation, brownout, and voltages that are too high or too low. (The printed text and instructions of this surge protector are in Spanish. )
Delay Function: If the device encounters (electric power) voltage fluctuations, it will protect the appliance by providing the output until the voltage stabilizes. The "DELAY" indicator will turn on to inform its user. The appliance will be delayed for 3 mins to confirm that the voltage is stable so that it can be re-established.
Working Principle: As there is an interruption in the current flow, the voltage surge protector gives an interval of 3 minutes to allow the voltage to stabilize. Additionally, the voltage surge protector provides protection against voltage spikes that can damage electrical equipment.
Adjustable Voltage: The minimum voltage capacity of the protector is adjustable. It can be adjusted from 170V to 265V according to your needs. (Adjustable position is at the back. )
Applicable Equipment: The voltage (surge) protector suits Air Conditioners, Freezers, Ice Makers, Washing Machines, or any Large Appliances
