It has supply mode which constantly provides a stable voltage of 13.6v to vehicle for programming. The most important is that it is not expensive, only around US$150. Take a look here CTEK Multi XS 7000 Battery Charger - cars, caravans etc - eBay (item 290237996446 end time Aug-05-09 06:18:12 PDT) (for 240v input) and CTEK 7000 12 Volt Battery Charger Optima Odyssey Gel:eBay Motors (item 360167047098 end time Jul-12-09 07:10:15 PDT) (for 110v input).

this will not work , this is a charger only no power supply . you can tell it wont work because @ 15-20 amps you must have heatsink or cooling fans .

Hi TwinsPoppa, have you tried this PS to code your car? How does it work? Please keep us informed.

The one made in Australia is also a good one but much more expensive compares to Ctek one.

According to the spec provided by the manufacturer, for Ctek 7000 model, it only provides 7 Amp which is enough for coding the vehicle if you are not going to start the vehicle by this, and it has a mode called 'supply' mode to choose to constantly provide stable 13.6v. Same function for Ctek 15000 and 25000 models, but provide 15A and 25A respectively. 15000 and 25000 models are more expensive. If you look into the detail of the product features and spec, you will see it. Only 7000, 15000 and 25000 models have 'supply' mode, other models like 800 and 3600 (3600 model is adopted by BMW as standard equipment for battery charger, part number 61432154949) do not have 'supply' mode, so they can't be used as power supply.

Base on the spec, I believe Ctek 7000, 15000 and 25000 all work for our purpose, but the AMP might not enough to start the engine.

rogerkiu ok if it has a fan to cool it may produce what they say , swithching power supply also have transfomer the smaller the unit less current supply .

a computer power supply could be made to supply about 15amps at 12.5 volts , and look at how many heatsink and fan to cool that .

The reason I picked the one from Australia is you can customize the specs to what you want and IMO is reasonably priced compared to the Deutronic models which are approx $2K. The Deutronic are adjustable in voltage but I used the specs I posted to get a constant 13.8v. Using 14.2v spec, taking into account ignition on, will be about 13.8v. Again, I just took my specs from what I could find from the Deutronic model used by BMW.

When you turn the ignition to Position 1 this will draw some power. Same if you have any accessories on. Obviously, you don't want to have accessories like the radio, fan, etc on.

The main reason the Australia one is expensive is the shipping which was $75 for me.

Again, I just want to remind everyone my experience so far: all my prior coding was not using any charger or PS. Ask Justin if we used a charger/PS when replacing his instrument cluster at the Connecticut meet. Hint: The answer will be NO. :D

IMO if your car has a good battery you probably don't need it if your doing the stuff I've been doing so far. The charger/PS, for me, is just a pre-caution in the future.

If you ever had to code a module for an extended time or will be doing extended diagnosis (more than 15- 30minutes), then definitely get the charger/PS.

Hi,

You need to review our PS400 or EPS1245 both are within this link.
http://www.element82.co.nz/Products/tabid/170/CategoryID/97/Default.aspx

The first is a power supply with charger functionality. The second is a charger that will increase voltage and current as required but is not a power supply as such like the feature offered with the CTEK XS7000 you may of seen.

Additionally the CTEK when in power supply mode doesn't have reverse polarity protection or anti spark as its supplying power from the time its turned on. I believe either of the EPS units would work with a small compromise for one feature from each that may give you your alternative your looking for.

Not sure what the prices are on the product (DBL800) you've noted but our units are around the $980+GST

Regards

So really I am still looking...
