Difference between surge protector and adjustable voltage protector

Date:2025-01-10   Click:488  

Surge protector and an adjustable voltage protector are both designed to protect electrical devices, but they work in different ways and serve distinct purposes:

Surge Protector:


Purpose: 


Surge protector protects devices from sudden, high-voltage spikes or surges (e.g., lightning strikes, power grid fluctuations, or switching on and off of heavy machinery).

How surge protector works: 


It uses components like varistors or gas discharge tubes to absorb or divert the excess voltage to the ground, preventing it from reaching your devices.


Surge protector key Feature: 


Surge protectors don't regulate or adjust voltage levels. They only respond to spikes that exceed a certain threshold, often measured in joules (energy absorption capacity).


Common Use: 


Power strips with surge protection, whole-house surge protectors, etc.



Adjustable Voltage Protector:

Purpose: 

Adjustable voltage protector protects devices from over-voltage (when the voltage is too high) and under-voltage (when the voltage drops too low).


How it works: 

It monitors the incoming voltage and adjusts it if necessary. If the voltage exceeds or falls below preset levels, the device either cuts off the power supply or activates a protection mechanism to prevent damage.


Key Feature: 

Adjustable voltage protectors allow you to set the minimum and maximum voltage levels, providing more control over voltage stability.


Common Use: 

Devices sensitive to voltage fluctuations, such as appliances, industrial equipment, and electronics that need consistent voltage.


Summary of Key Differences Adjustable voltage protector VS Surge Protector:

Surge Protector: Only deals with sudden voltage spikes.

Adjustable Voltage Protector: Deals with both high and low voltage levels, and can be adjusted for specific thresholds.
