Automatic Induction Protection: Safeguard your electrical devices by cutting off the current flow during voltage spikes, instant surges, voltage fluctuations, brownouts, and voltage that is excessively high or low. (The printed text and instructions on this surge protector are in Spanish. )
Delay Function: When the device detects electric power voltage fluctuations, it shields the appliance by maintaining the output until the voltage stabilizes. The "DELAY" indicator lights up to notify the user. The appliance is held off for 3 minutes to verify that the voltage is steady before power is restored.
Working Principle: As the current flow is interrupted, the voltage surge protector provides a 3-minute interval to allow the voltage to settle. Additionally, it offers defense against voltage spikes that could harm electrical equipment.
Adjustable Voltage: The minimum voltage threshold of the protector is adjustable. It can be set from 90V to 140V based on your requirements. (The adjustment point is located at the back. )
Applicable Equipment: This voltage surge protector is suited for air conditioners, freezers, ice makers, washing machines, or any large appliances
