## Overview

The Norstar DAVR-3000 is a robust 3000-watt step-up and step-down voltage transformer with an automatic voltage regulator designed for single-phase 50Hz applications. Featuring a digital display for precise voltage monitoring, dual circuit breakers for enhanced safety, and a next-generation CPU for stable voltage output, it’s ideal for safeguarding sensitive electronics and refrigeration appliances from power fluctuations.

## Description

3000 Watt Max Load Capacity. Great for use with electronics and refrigeration appliances. Norstar DAVR-3000 110/120 to 220/240 or 220/240 to 110/120 Step UP and Down Voltage transformer and Automatic Voltage Regulator . …Single Phase. Input/Output frequency 50Hz. - Digital display meters are more accurate stable and easy to read the voltage status at a glance. - this unit comes with individual circuit breakers for both input and output voltage along with dual switches which ensures double protection. - This unit has a built-in new generation CPU which ensures consistency and stability to the AVR unit.

Review: This thing is amazing - I was blowing out circuit boars on my AC unit (Split System) and it was due to overvoltage. My 120V power from the pole would go up to 140V periodically and blow the board. After 4 replacement boards I found this unit that has solved all my overvoltage issues. I plugged the AC into this and have not had an issue since June 11th 2021. We are in NC and this unit works hard to keep our Laboratory cool. Without this unit I would have already blown another circuit board. I'm very impressed as to how well it works. It keeps the power at a steady 110V. I'm sure that it would do the same for 220V.
Review: Terrible product and false advertisement - First of all, this transformer will not give you 50hz as stated in the description. If you have a 230v device that requires 50hz frequency this thing will not work but it states it does. See my video. It also does not dispaly accurate voltage, always stays at 220v. Secondary, the unit came damaged, see my picture. It looks like everyone gets this this item banged up. Maybe they throw them off the roof to test durability.
