VFD Inverter 380V 4KW,3 Phase 380V 12A Variable Frequency Drive Converter,Variable Frequency Converter,for Motor Speed Controller PWM V/F Control

It looks like it works as required with my ATC 1.8KW 24K RPM spindle and importantly the external braking resistor terminals are functional. Without an external resistor the minimal deceleration time from max RPM I was able to achieve was about 9s. With an external 100Ohm braking resistor the minimal deceleration time got down to ~3s. It probably could go down even more but 3s is good enough for me. The temperature of the braking resistor with a heat sink attached jumps during deceleration to over 80C confirming the braking resistor is working.

Good product good price easy to program for different motors

We fitted this 22 days after receiving it - it worked immediately and one week later it stopped working It is outside its automatic return period

It does work.. However there are massive sparks whenever you connect it to power as seen in the pic, any fuse under 10A would blow. On top of that after you unplug it, the socket itself holds power and would electrocute you if touched. I know the manual schematic shows a double switch, but still. I now have to invest into a soft start of some sort too otherwise it will destroy it’s plug and house socket. There is no internal power button to turn off the electronics(display, fans etc) there is only start stop for the motor, hence, you can’t leave it plugged in. Fans are really noisy but probably okay for a garage.

Product purchased and delivered on time but Fitted and does not work, save yourselves the hastle the price is too good to be true.Straight out the box Fault codes and smell of burning with no motor connected.Electricians fees to pay now on top of more time and money wasted.Never again

the item turned out to be better than in the description not by 1.5 kw, but by 4.0 kw
