Alex,
It’s a Taian t-vwerter N2 203 M 2.2 kw but it’s quite old, you see ABB and other ones coming up on E-Bay regularly.
The thing itself is great fun it has about 120 different parameters some of which have dozens of options, it can also be used on closed loop control if you want.
-It can generate a 3 phase output from 0.1 to 400 HZ
- Adjustable accelerate and decelerate times, I have this set at 2 seconds which is quick enough and means that you don’t exceed the mains fuse rating when you switch on.
-It can be controlled in dozens of ways for example will not restart after a power failure until you press the reset button. An important safety feature.
-You can set upper and lower frequency limits and program it to skip certain frequencies if for example you had a vibration at some particular speed.
-The efficiency is very high, even at full load it doesn’t get warm, so all the input power is going to the outputs and not generating heat.
-You can set the output voltage
-It can work with motors with between 2 and 8 poles
The list goes on and on but obviously you won’t need most of the features. When I bought mine I spent about a week in the workshop just playing with the thing.
I can only say I’m totally satisfied with these things.
By the way I’m am industrial process controls engineer and you would be amazed how many of these things are used to drive pumps, fans, compressors and other things in industry these days. This has mushroomed over the last 10 years and is responsible for getting the price down to the DIY level.
Cheers Don.
