Meanwell PB 1000 vs Iota DLS -75

Re: Meanwell PB 1000 vs Iota DLS -75

You guys turn my world upside down with the all the talk about efficiency. I am charging batteries @ $.64 a hour. I know I sound like a Iota Fan boy, but it's tough like Mule. It doesn't care if it's >99 deg in a enclosed compartment or where it's at. It's proved to be good and puts out it's rated output hour after hour, but I am ready to find a better mouse trap if it's out there, my customers demand it.

There are several things that give me pause about the Meanwell.

1) It's a multi-bank charger, that I said I'd never buy again. That is the first thing to fail on them.

2) It's only 70 mm thick, that means it'll have a little 40 mm fan. That means it'll have limited air flow and probably cut it's output. Time will tell.

Re: Meanwell PB 1000 vs Iota DLS -75

All I want to do is charge batteries as fast and reasonable as possible. I have two choices a Honda EU 2000 and a 20 KW generator. I figurer it's either $.64 a hour or $10.81 a hour.

I suspect that most people are not using their Honda EU2000 for anything but to power their stand alone charger. There could be someone thats concerned about the PF of their charger. I see some posters that talk about their Meanwell chargers, but then they say they really don't know because they don't use them enough to know. I want to get down where the rock hits the road. The Generator runs on, the chargers output is what's important, the Magnum is the worse, it spent at least 50 % in " charger cut back mode " I thought with it I could have better use of the power I was producing, but it went to e-bay as a failed.

There is one other thing I haven't mentioned, paralleling the charger output on to the Inverter inputs with the battery bank. I did a set up where I could measure the current flow and the charger output will be used by the inverter first and the excess will go to the batteries, load the inverter above the charger out put and the flow reverses.

The new Xantrex SW3012 is doing something like the above with what they call " Generator Support " When the draw on the Incoming power reaches the support level, it drops the generator and charger, then the incoming power is diverted to supplying the batteries enough power to support the load. Does it have 2 transformers ??, it weighs 73 lbs. It's kind of a weird way to give support, but it is a 3000 w inverter and with a Honda EU 2000 it would give you more than twice the power and it does have a 150 amp charger, a Honda might pull half of it, or give you 75 amps of DC support.

Not quite.
Generator support means that rather than overloading the generator with a big load the inverter will gradually change from charging to not charging to supplementing the generator's output to supply the loads. This function is available on some GT based inverters due to the fluid nature of the AC connection; unlike a standard off-grid inverter there is no transfer switch which clicks in/out but rather bidirectional circuitry through the inverter's transformer which allows it to either "send or receive" power.

That is true with a Inverter that has a syncing capability. Who is the arbitrator of the meaning of terms in the Inverter world ?? I'd call it " Inverter Support " , I guess they can call it whatever they want, but that is how I was told it works.

Magnum is about to release a new " Generator Support " Inverter ( MSH2812 M or 24 M) that is supposed to have true support as we know it. Where it is actually coupled and synced to the generator and will give you double the power. It has been promised for over a year, no joy yet.

For all you that are waiting with baited breath for the Meanwell PB-1000 test you'll have to wait a little longer, I never received it after 12 days and I called, No record of the original order. I did place a new order, so you'll have to wait a little longer. Shipping normally takes 6-7 days from California to me, but 12 was way to long.

I hope that "no record of original order" includes no charge on your credit card.

Thank You for mentioning that , nope, no charge. I did find out that their system is not automatic, the orders are batch fed manually into their system. They are really wholesale company and don't do that many retail orders of 1 unit. ( Power Gate )

Re: Meanwell PB 1000 vs Iota DLS -75

Ok, I finally got around to testing the Meanwell PB-1000-12. I am going to tell you the good, the bad and the ugly of it. The good is it's good looking unit, great fit and finish. First off it has a programed float voltage of 13.8, my opinion thats very high. Second the unit will not function if there is any load on the battery bank it's charging. All it does is surge up and down and the fault light goes on and off. If you take the load off, it'll go back to charging. Not the kind of charger you want for a Solar stand alone charger. It never did put out it's rated 60 amps.

The Test :

I pulled a 1100 amp hr bank down 300 amp hrs, both chargers had #2 cable to the bank and the same input. I did have to cut the loads off the bank to get the Meanwell to function. I couldn't be any more fair. I used the only measure I have, what I put in and what I get out. If you know a better test, I'll send it to you and you do it.

The Math :

Meanwell

Input 7.39 amps ac @ 120V

Output 51.4 amps dc @12.7 v

51.4/7.39 = 6.95 DC amp's for every 1 ac amp of input

IOTA

Input 8.64 amps ac @ 120V

Output 75.9 amps dc @12.7 v

75.9/8.64 = 8.78 DC amp's for every 1 ac amp of input


My conclusion is that if it's got PF in it, it's staying in it. I'd avoid this charger like the plague, don't waste your money. The IOTA is solid as a rock and a great buy and you get 26% more amp output for every amp you put in.

P.S. I got $289 in it ( used 30 minutes ), first pm I get for $140, I'll pay the shipping can have it, plus I'll throw in the $7 cord I had to buy.
