Amazing thing

I have burnt out the circuit boards of my AC unit (split system) which is due to overvoltage happened. My off the shelf 120V power supply would regularly go up to 140V and blow up the board. After replacing 4 circuit boards I found this device which solved all my over voltage problems. I connected AC to it and as of June 11, 2021 I have had no problems. We're in North Carolina and this device is working hard to keep our lab cool. Without this block I would have torn down another board. I'm very

Pros
  • This unit has a new generation CPU built in which ensures the consistency and stability of the AVR unit
Cons
  • Could have chosen a newer model

. Norstar-3000 is in its 3rd month and so good so far. Bought this DAVR for a 110v pair

I used my Norstar-3000 already in the third month and so far so good. I bought this DAVR for a pair of 110v 200w per channel amps and a couple of sound processors in my 2 channel home theater system and it barely gets warm. I just found out today that it is designed to run continuously without overheating so now I don't have to worry about forgetting to turn it off before leaving the house. The numbers on the top screen keep changing, say from 237 to 245 volts, while the screen below keeps…

Pros
  • Norstar DAVR-3000 110/120 to 220/240 or 220/240 to 110/120 Step-up and step-down voltage transformer and automatic voltage regulator
Cons
  • Available in white only

Buyer Warning. After 2 months I now have 4 very large paperweights.

*I originally bought 2 "Norstar DAVR-3000 3000W, 110/120 to 220/240 or 220/240 to 110/120, step down and step up voltage converter and automatic voltage regulator in October" " received (2020).) . - BOTH TRANSFORMERS WERE DAMAGED -- I have reported that I believe the items were already damaged prior to shipping to me!.?.?!. -- Both had significant damage to the bottom of the blocks but the boxes showed no noticeable damage!.?.?!.* As of yesterday 31st December 2020 I have received both…

Pros
  • Digital display gauges are more accurate, more stable and easy to read at a glance.
Cons
  • Not the best
