UK customs and then parcelfarce ripped you off for 44 pounds then...

[shirley_hkg]

Those STEP-DOWN inverters are 30V only .

The other is a 4-digits voltmetre .

I said I throw them in.

Damn. You got ripped off £50.

Understood, thank you Shirley

Duty & Tax was something like £37, plus £12 Parcelforce admin fee

I don't mind the Duty & Tax so much but I think the £12 admin fee is a bit of a swizz. But it was the same with my revolectrix PL8 order, FedEx also charged a £12 admin fee for paying customs duty on my behalf. The shipping firms must con an extra £12 quid out of a lot of customers.

BUT the big ticket item, two separate boxes of lifepo4 cells sailed through customs without paying a penny to anyone . And that would have really hurt if I'd got clobbered on them.

So I can't grumble too much, I'm just pleased to have my parcel . And much more stuff in the box than I realised. I thought I would still have to buy some extra bits, but everything (and more) is in the box so I won't have to which is a bonus. Plus apart from say a packet of two of crimp/solder lugs, there's enough stuff if I put lifepo4 in the Salsa. And already enough connectors if I want to convert the Salsa's lead XLR charging to SB-50 charging.

EDIT: And it's nice to have things to do and it keeps me occupied

@Scooterman & @steves1977uk ,
mod guy forgot to remove the front air filter . Cut it from outside and throw away .

[Scooterman]

Will do Shirley

For powering the PL8 for charging the 90Ah 2P8S lifepo4, do I set the PSU to 24v and say 40A, and perhaps set the PL8 supply tab to 24v and 35A?

I'm not sure?

For trial charge of lifepo4 using new PSU PL8 and temp cables, I wasn't going to set CC above 25A as temp cable aren't very thick.

Sorry for basic question, I want to try and avoid making mistake with PSU set up.

[Burgerman]

Set power supply 24V max amps. For everything.

Set PL8 input tab to 10V lowest as you may want to run it from a 12V or battery supply at some point. Set input to 30V and to max amps that is the same as or a fraction less than your power supply max output. So if thats 50, set to say 48 max.

[Scooterman]

Thanks BM that’s great

[Scooterman]

Been using the new PSU today, it's a nice power supply.

I removed front panel and took out mesh grill. I was thinking of drilling and tapping the front say M4 and fitting one of these https://www.ebay.co.uk/itm/80mm-Axial-F ... 3226634624

I'm concerned the fan blades might get broken without some protection

Set input to 30V .

I've done as you suggest BM, but the PL8 DC supply tab doesn't have a voltage setting?

[LROBBINS]

I replaced the perforated plastic with a piece of fiberglass window screening. Hardly blocks airflow and keeps debris and fingers out.

[Scooterman]

That's what I'm bothered about, my fingers Although it wouldn't hurt as it's only plastic fan. I'm more worried about breaking the fan, and making PS look nicer with some form of front grill. I really like it, it's very well made

[Burgerman]

I've done as you suggest BM, but the PL8 DC supply tab doesn't have a voltage setting?

My bad. Its automatically 30v max. Gives an error if exceeded.

Okay understood

PS: What is the earth terminal for?

[Burgerman]

What earth terminal? You mean the green one?

On shirleys supply/charger?

Its tied to the walls ground. And case. The red, black power out are FLOATING, and not tied to a wall. DONT connect the green one to anything. Other than your multimeter if doing technical stuff.

Also thats a 50A supply. Those terminals are good for 20. More is too much really, they will get hot or melt. So use ring terminals and not 4mm banana connectors, and dont go much past 20A. Thats why I added an anderson to the rear of mine so I dont melt anything...

[Scooterman]

I like how you've added the Anderson connector.

I won't connect anything to the earth terminal, I was just curious.

[shirley_hkg]

Remove the back plate , and you will reach the 2 output terminals .

You purchased pre-made SB50, didn't you ?

[Burgerman]

The andersons with cable already attached are going to be very hard to fit.
You will need a loose one. Easy to buy on ebay cheap.

Theres not exactly a lot of room in there. Mine has thinner silicone heat proof cable, (same size as the PL8 leads) since its more flexible etc. It runs from the boards output (with 2 ring terminals soldered on of course) to the Anderson. And a 2nd wire, from the anderson to the front facing connectors.

So the andersons have 2 wires in each terminal. Its the best way to make a neat job. Also everything is soldered.

[LROBBINS]

With a small screwdriver to hold down the springs you can also pop the pins out of the Anderson connector in order cut the case to fit it, then pop the pins back in.

[shirley_hkg]

I think BM means bi-wires at each Anderson pin ; as a Y-spliter.

One goes to the supply , and the other goes to the front power pole.

Interesting. I have an Anderson on the back of mine, but wired it up a bit different. I have two sets of wires connected to the board's outputs(via crimped/soldered ring terminals). One set runs to the front connectors, and the other to the Anderson. I used 10 Awg silicon wire I believe. And yes its a very tight fit in there, especially with a 25mm thick fan installed. But it all fits after a bit of fuss.

[Burgerman]

Yes. Strip 1.25 inch of insulation in the middle of a wire. Easy on silicone as its soft. Fold wire in half. Insert into Anderson connector pin and crimp/solder.

Supply >>>>>>>>. Anderson >>>>>>>>front connectors

Makes the fight for space etc easier.

I don't mind the Duty & Tax so much but I think the £12 admin fee is a bit of a swizz. But it was the same with my revolectrix PL8 order, FedEx also charged a £12 admin fee for paying customs duty on my behalf. The shipping firms must con an extra £12 quid out of a lot of customers.

You can tell FedEx to take a run and jump. It worked for me.
http://blog.adamowen.co.uk/dont-pay-fed ... ement-fees

The same might work with parcelforce.

[Burgerman]

You dont get a delivery until you pay. They hold your parcel hostage. Often only sending a letter telling you to pay first while no attemp to deliver is made. B******ds.

They were a socialist (gov run) company, the royal mail, royal post office, all the same crap. And they were the only option at one time. So thats what you get. All nationalised companies behave the same way. Like the NHS. The world owes them a living. Now they are privatised, but still work the same way as its in their DNA. And they get the bulk of the business at the ports from foreign carriers and post boxes etc by default. AVOID the scammers.

In the UK DPD are by far the best with real time live tracking by house and number and accurate delivery time withing a few mins. Curt delivers mine. Looks like a pedophile online, but he is very reliable. Hope he isnt reading this

[Scooterman]

FedEx sent me a bill via text for duty and the £12 after I revived the goods. I did read that blog post before paying, but I wasn't sure if it would work or not and frankly didn't want the hassle. But I do appreciate they rely on people like me capitulating, and FedEx probably don't bother chasing non-payers.

Parcelforce was different, they wouldn't release my parcel until I paid the fee and duty.

The UPS lifepo4 cells sailed through without paying anything. And I would rather pay tax on the PL8 and PSU than I would the cells.

I agree DPD are good, like my DPD driver too, he's alright.

Hi I fitted a replacement grill. I was reading in the user manual that the PSU can be used as a three stage charger for lead acid. Is it okay to fit Anderson’s to my power chair and use the PSU to charge them Without the PLA8. My batteries Specification states maximum charge rate 22A. So I won’t be pushing the PSU too hard

[Burgerman]

IF you fit the dual andersons as on my page here, you can charge them at 44A in parallel, from that power supply directly.

If you decide to just add 1 anderson you can charge at 22A in series at 24V.

If you charge via XLR you can charge at 12A via the normal charge port.

You can do that 2 ways. Either in power supply mode as 12A and correct voltage for the battery and for 8 hours.
Or
In 3stage mode, so it goes at CC/CV till it reaches say .2A and then reverts to a lower float indefinitely.
Both work fine.

8, OVER Volt & Amp output protection ; with user adjustable criteria (Set max Amps, 30V for PL8 for safe operation)

Hi, how do I do this. I've entered menu option 8 but it says relative voltage, and the max value is 3.0v.

How do I set PSU to max amps and max 30v output?
