I am looking for Fans for Axpert.

Maybe someone here knows where one can buy these?

I have already bought 2 similar 4 wire fans from RS Components at their astronomical pricing, but to no avail.

Eagerly awaiting any pointers of where to get, or maybe someone has one or so Axpert beyond economical repair that could assist?

Thanks in advance

Riaan

Hi Riaan,

Did the RS Components fans not work?

Do you have a part nr?

Morning @francois Nope, of the 2, one does not work spin or anything, the second one by swopping the 2 control wires, can get is to either not start up, or to spin at full speed.

I will look for the part number on the 1st fan, the second fan was:

781-5089  Sanyo Denki San Ace 9GA Series Axial Fan, 92 x 92 x 25mm, 116m³/h, 3.36W, 12 V dc

I find that the fans used in a PC desktop case work the best (Not for the Axpert, but in general). If you have a 12VDC supply to power them, they are cheap, easy to get and pretty reliable. 
The larger the fan the less noise they make, so if a 120mm will work go for those. You can get them from R100+ at your local computer shop.

Thanks for that @louisjvdw, Agreed, but on the axperts those do not do the job.

The 4 wire has an additional PWM pin and a sense wire vs the standard 2 wire single speed fan.

So the inverter see a fan failure even though the fan might be spinning OK.

The Axpert 3kW for example has the 3 wire, so basically only additional  PWM for speed control.

Following up on the fans. Some of the CPU cooler fans on the pc's has either 3/4 wire to control the fan.

 

Wired like this.

Or you can check out this post if that makes more sense.

Contact @Chris Louw He has 2 x Axperts that he is stripping for spares.

I'm getting 01 Fan Warning on my 3kva 24V MKS Plus. The one fan has been replaced by the previous owner. Both are spinning when the inverter starts up. Can anyone tell me which is the original one and where I can source a copy to replace the other one with in order to get rid of the warning?

The SUNON is the wrong fan . Seems they made the hole larger to fit it . The right fan is only 60x60 . The ADDA fan only have 3 wires not 4 like the 5kW . The 2nd photo is a fan from a later version .

Thanks @Chris Louw. Any idea where I can buy the ADDA fan from or how to jippo the Sunon so the warning disappears? I see Mouser has it but I'd have to import it.

Sorry can't help . Courier cost at Mouser R600 for 250 gram . If we beg maybe a electronic expert can disable the alarm .

If you're looking for a 60mm PWM 4-pin fan then this looks like it should work? https://za.rs-online.com/web/p/axial-fans/1919374
