Review on π Norstar DAVR-3000: 3000W Step UP/Down Voltage Transformer & Regulator Stabilizer by Norlan Pippinmd
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 impressed with how well this works. It keeps the power at a stable level of 110V. I'm sure it would do the same for 220V.
- This unit has a new generation CPU built in which ensures the consistency and stability of the AVR unit
- Could have chosen a newer model
