Post Subject: Hello again !Posted by Petrasescu_Lucian on: 10/18/2009

As I've said a couple of months ago, I got my APS 700i regenerator a few days ago... I didn't "audio-test" it so far but there will be plenty of time for that later. I've fired it up to see if it's workong properly and everything looks good so far.
There are some notes I would like to point out for those out there that are interested:

1. The unit puts out on "Line Normal" mode perfect voltage readings: Live->Neutral = 230V; Live->Earth=230V and Neutral->Earth=0V (I live in Europe)

2. In the "Battery Backup" mode the voltages are slightly different: Live->Neutral = 234V; Live->Earth = 122V and Neutral->Earth=112V

3. The two fans in the unit are transistor controlled and are quite hearable in my entire room. They are not intrusive but somewhat distractive.

4. The unit runs quite cold for the most part of time

5. When the unit is in "Battery Backup" mode the only noise that comes from the unit is from the 2 fans. If I manually stop them there is absolutely no noise coming from circuitry inside

6. When the unit is in "Line Normal" the unit puts out quite an annoying buzz in the entire room even with no load that is significantly more distractive than the fans.

7. The LCD display is erroneous for most of the information displayed so all my measurements were done with a quality digital multimeter.

I'll do some oscilloscope measurements when I have the time and will post back.
