it is a small, good looking vfd. i was amazed that there has gone some love into this product. it came with a booklet with a lot of info. it came quickly. will test it later
The VFD looks and feels made professionaly, and is well documentated. Works fine but i had a problem with the digital inputs. (were high all the time, even without connection 28VDC, so i can't use it with an external panel.) AliExpress returned the money very fast after i uploaded the evidence. But it seems that the seller has no idea what he is talking about. I would buy an SAKO inverter again, but not from this seller.
