Automatic Voltage Regulator (AVR) Product Range for Zimbabwe

An automatic voltage regulator (AVR) is a device that regulates electrical voltage automatically, thus, it takes a fluctuating voltage level and turn it into a constant voltage level. Our household AVRs can be used to protect you expensive refrigerators, computers, televisions from blowing when your power supply fluctuates. We also supply heavy duty AVRs for businesses and industrial companies looking to protect any expensive equipment from voltage fluctuations.

Listed Below are our Single Phase automatic voltage regulator (AVR) products and our three phase automatic voltage regulator (AVR) products. Simply look at the descriptions next to each product for our recommendation on what to use each model listed below for as well as in depth technical specifications for each of our models.
