    Looks like it is able to be configured.

    Looks like VC has covered it.
    I have been systematically placing the Powtrans inside protective cabinets although noise is not why I do this.

    Except for one of the Huanyangs I don't notice the noise but agree the SPL from multiple VFD fans can be irritating.

    Here is some hard data on SPLS
    The SPL measurements provided for each VFD is for 1m from the VFD at head height above the floor.
    Shed background (nothing running) was 45dBA

    The 1HP VFD on the shed ventilator does not have a fan so it was the same as shed background.


    The Huanyangs produced the following SPLs
    2HP on the WW lathe 55 dBA
    2HP inside a 10" pedestal grinder cabinet (includes a 100mm 250V fan), 54 dBA
    2HP on the grinding station (includes a 250V relay that hum a fair bit) 61 dBA.
    4HP on Belt Sander; 58 dBA,
    4HP on BandSaw 56 dBA
    4HP on DC, 59 dBA

    Powtran
    Test Bed 3HP 9130 52 dBA (not inside a cabinet)
    2HP PI160 and 0.5HP PI130 inside Hercus Mill cabinet includes a 92 mm 240V vent fan, 48dBA

    2HP SAJ VFD inside protective cabinet on DP, 47 dBA includes a 100mm 12V ball bearing fan

    When all VFDs are on and I'm standing at my main bench, 59 dBA
    The HYs tend to be noisier although maybe even less so because they are all bar one inside cabinets.

    Powtran contacted me yesterday to say that as from July 1 their cost to use PayPal for small number VFD purchases will increase by ~US$35 per transaction which obviously puts a large hit on the purchaser of 1 or 2 VFDs.

    The reasons are complicated and I can try and explain it if anyone wants to know, but what I wonder is if it has something to do with deteriorating US/China relations.

    The remaining option is to use Western Union (WU) Transfer. This will be a few $ more expensive than the current PayPal arrangement for the purchase of a single small VFD, about the same if you purchase 2 small VFDs, and cheaper if you purchase more than 2 small VFDs.

    I have explored the WU payment portal and it is a bit more complicated than using PayPal, unlike PayPal it does not guarantee the the receiver will receive a specific amount.

    There is also the slight concern that WU is not as secure as Paypal and would be interested in hearing from anyone that has used WU on-line transfers recently and what their experience has been.

    I am in ongoing discussion with Powtran to see if this can be resolved.

    $35USD seems a bit steep seeing they already charge a premium for PayPal vs Western Union - I would like to understand what the cost difference is caused by so I can convince myself it is justified. When I bought off them recently I elected to pay via PayPal and pay the premium (5%) as I was unsure about how to even go about paying via Western Union. I would like to also know if anyone has any experience with Western Union and whether the system is secure (I notice that a lot of Ali Express suppliers use Western Union).

    The USD$35 is not a fee imposed by Powtran or PayPal but by PowTran's Chinese bank as a results of changes in papally funds transfers.

    As from July 1 Paypal will no longer allow Chinese companies like Powtran to transfer their money from PayPal as Chinese currency (CYN). Instead they are forcing the Chinese companies to accept deposits into their Chinese accounts as USD. Powtran's chinese bank then charges Powtran US$35 for as a minimum fee to convert any amount of USD to CYN. You need to remember that Powtran sells VFDs by the container load so when they sell 1000 units $35 is nothing but when you sell one it's a lot. It's pretty unusual to be able to buy a US$100 item direct from a Chinese factory.

    When I bought off them recently I elected to pay via PayPal and pay the premium (5%) as I was unsure about how to even go about paying via Western Union. I would like to also know if anyone has any experience with Western Union and whether the system is secure (I notice that a lot of Ali Express suppliers use Western Union).
    Paying via Western Union is pretty similar to PayPal. You register and can elect how to send money. They charge a flat fee of $10 for amounts under AUS$500 and $18 for amounts above that up to another level.

    I deal with other Chinese companies that have told me a similar story. The difference appears that when they transfer money from PayPal they do so as a large amount from many transactions so that the $35USD is not per sale but per money transfer. This explanation may have lost something in translation but that is how I understand it - at the very least they are not planning on charging $35USD per order (although that may change in a couple of days when it takes affect). That coupled with a possible 10% GST charge (still haven't got to the bottom of that with many contradictory views as to what is going to happen) will make 1 Jul an interesting day!

    I guess as a company it makes PowTran's position difficult and they need to do what is best for their business. At least the Western Union option is there so might be the way to go for future orders.

    I have just completed the western union transfer after some emails with Nicole. Once this has been completed i will update this thread with how it works.
    I have ordered :

    PI9130A 004G1 : USD160

    Resistor RXLG:500W/40R: USD15

    Freight: USD58

    Total cost : USD233.
    so a 4kw single phase input 9130 series drive with braking resistor.

    For the WU transfer , you can use a FIRSTFREEAU as a promo code to get the first one free, saves $18 AUD fee.

    Also you must be well regarded by Nicole, Mr Bob from Australia.

    Do you know if there is an IDC female to male cable available for remote mounting the Control panel?

    I just made my own from 10 way ribbon and these two IDC 10 way plugs from Altronics.

    Thats a P5310 on the left and P5060 on the right.

    I wish I could have found male plugs that crimped directly onto wires but the only male plug I could find was the 5310 which is Male/Male to attach to a circuit board.
    Fortunately the 5060 plugs into the back as well as the front of the 5310.
    So on the remote panel you need a 5310 to plug into the panel and then a 5060 to plug into the back of the 5310 and attach the 10 way ribbon cable to the 5060.

    Somewhere in the 10 way cable path you actually need a cross over cable so the following is a bit of a kludge but it works.
    If you don't use a cross over the panel will not even light up or maybe it will light up and flash.

    For the VFD on the LHS I made up a crossover cable from scratch ie PITA.
    You could get away with 2 x 5060 and do the crossover on the cable end itself but I had no chance with my fat hands

    Xover.jpg

    For the the VFD on the RHS I made a cross over by using the following
    Forget about the FX plug.
    F1 is a 5060 as are F2 and F3, In between F3 and F2 is a 5310 - the effect is to create a cross over cable that works.
    You will have to play around with the orientation to get it right.
    Remember to keep the verticals in the same orientation but the two sides need to be swapped over.

    I found some 10 way IDC female/male cable some on ebay - not the most elegant implementation with the double cable - it looks like they are sort of "home made"

    Because of the way they're made they could be reconfigured as cross over quite easily.

    Which Pins need to be crossed over? I have some of these on order. https://www.ebay.com.au/itm/5Pcs-2-5...72.m2749.l2649

    With those plugs you should't need to cross them over. As long as they match the originals pin for pin.

    There is also these ones but they are only short, but probably still suitable for some applications.

    My older powtran came with an ethernet cable to run the display, is that not the case with the newer units?
