I was just reviewing stable power supply vendors. Particularly the:

- Schumacher power supply model INC 700a

- Deutronics stable power supplies


Are any of the Schumacher stable power supply products currently re-branded under a different name ?

Have you come across a brand that is more price competitive than the Schumacher products ?

 

What are your needs? Do you want to do extensive programming and want a steady 14.4V attached to the car for this reason? If that's all you're after, it would be pretty easy to build a 20-30amp power supply with fixed output for 1/4 of that. Or buy an 'off the shelf' supply. I found a 50A 12V SMPS on Amazon for $50.

 

The only work I do is with Insta and INPA.

I was getting ready to use the software to bleed the ABS, DSC pump, calipers and the battery was getting weak. I knew I needed a constant power supply and have been putting it off.

I'm just looking for a constant 13 volts for about an hour. If I had this device in the garage I'd use the BMW software a lot more often than I do.

You say you have a 50A 12V SMPS from Amazon.

Did it come with alligator grips you could attach to the positive jump block under the hood? Which 50A 12v unit do you have?

 

Like this:
You can tweak the output a little. Attach your own leads. A smaller one would probably suit the needs, say 20-30A.
But I've never had a problem just using a battery charger I got from Crappy Tire: https://www.canadiantire.ca/en/pdp/m...1976p.html#srp

 

Looks like our day just got better.

The Schumacher 100 power supply used by many is $727

Schumacher rebrands this unit and calls it a DSR.

The DSR is $379. See below.

I can live with $379.

 

That's good news. I'd suspect that Amazon is hiking the price, but that's just me.

 

In conversations with Noco (who makes power products), they tell me their model G7200 can operate in power supply mode.

The Noco G7200 power supply mode delivers 13.6v continuously at 5 amps. It can be connected to the terminal block under the hood for circa 3 hours before it over charges the battery.

If you are doing diagnostic work with Inpa, Ista (e.g. bleeding the DSC and calipers) and find that your battery is going dead, it appears this Noco power supply could be a solution. Its circa $99 and a lot cheaper than the Schumacher model 100 for $722.

If you are updating, flashing the Schumacher power supply at $722 is going to be in your best interests.

Anyone have experience with the Noco G7200 in power supply mode?

 

No experience with that one, but I wonder why they say that it'll overcharge the battery after 3 hours if it's set to output 13.6V. Ideal float charge for a 12V battery is 13.5V, so an extra 100mV shouldn't be a concern.
