Yeah, what he said.
Chargemaster 1500 - no more scale drift!
- Thread starter uncle-buck
- Start date
Was told the machine has a built-in voltage regulator which automatically adjusts to the correct voltage.

It's a good option, not necessarily the best for every situation. The battery is rated at only 6 amp hours. Some users will want higher capacity so they don't need to recharge as often. Others prefer sealed lead acid batteries over lithium ion batteries. Still a very good option...

That battery will run a chargemaster at a 4 day match without turning it off and only lose 1 out of 5 bars of battery level. We do it all the time- never seen anybody have to recharge. I even run my barrel cooling water pump off the same battery and have never ran it down

Low temperatures affect mine too.
Called RCBS and was told not to put 12 volts into my Chargemaster because the one I have specified 9 volt input, apparently 12 volts worked for you guys but check this out.
A multi-voltage power supply, 5v/9v/12v in the same package.

So here's a potentially dumb question.
If I take the 12 volt deep cycle camper battery that stays on trickle charge in my garage and hook my power inverter to it and then plug in my Chargemaster to run off of the inverter, will I have accomplished anything versus just running the CM off the wall outlet?

No, in fact any issues you may be having might get worse !
The inverter will potentially introduce more noise into the supply than just from the mains supply.
I just checked my CM wallwart and it's a 12V 1A switchmode for worldwide mains voltages.
These things in themselves can be electrically and EMI noisy and the preferred remedy is always ferrite magnetics.
~3 yrs back when a mate bought my new CM into NZ from the US I expected it to have a 110V wallwart as the 230V wallwart was either an option or a 230V rated CM was a somewhat higher price however a pleasant surprise awaited when the multi voltage wallwart was unpacked.
Running CM from a 12V battery should be no problem however a full and freshly charged 12V battery can measure close to 13V and if under charge 14V or a shade more. < This may be a concern.
If the CM power input circuitry is properly done using voltage regulators with sufficient voltage headroom there will be no problem.....I should really have a look inside mine.
I don't and my one and only access point is just 2m away.
RCBS also advised me to wipe the entire unit down with a anti-static cloth, they claim that will eliminate any drifting.
I think the anti-static advise is OK but one of the jobs I had was with a power company investigating stray voltage and radio interference issues and I can tell you that there is a lot of dirty voltage everywhere that a anti-static cloth aint gonna help.
I think a isolated power source is a really good idea.

Is this an acceptable power supply stabilisation device?
Plug it in to keep battery up. Run 12 v dc from battery leads to the RCBS 1500?
RCBS 1500 Located distant, grounded, anti static, other guidelines per this and other discussions.
I am going to get out the Boy a Scout Compass and "witch" for stray electromagnetic anomolies amongst my lighting, cell phone, multi outlet surge protector with an octapus bundle of wires every which way amongst my cluttered desktop. Will post results.

Running solely on battery power will solve about half of the issues a chargemaster has
I will look to see if the on off switch is on the power in. If it is then i can turn it off to drop powder and on to recharge.ok.
Other suggested solutions are tempting. I have a good handful of 3 cell lipo batteries along with charging gizmos and accessories. Options.
Great thread here.

"OK" This is interesting, as I said previously RCBS told me that I had to supply my 1500 Chargemaster with 9 volts DC and nothing higher.
So I got a 9 Volt system and to make sure I had the proper polarity I checked the ac adapter that came with the Chargemaster and discovered it was putting out 12 volts dc and apparently has been for many years and working just fine.
This is the first time I have found a power supply that had a output voltage other than what was stated on the supply unless it was defective.
I guess I call RCBS in the morning.

From this older thread.
"For the curious at heart RCBS apparently sells these things with a variety of power supplies or simply put AC adapters and even simpler wall warts. Myself and another member compared them with him having two units and me just one,My supply is a 9 Volt 1,000 mA unit and he had a 12 volt with one scale and a 9 volt with his other. Using my power supply at 9 volts the scale powered up draws about 33.7 mA so let's be generous and say 35 mA. When dispensing powder (motor running) the total current draw is 190.0 mA, so if we bump that a little in the interest of nice easy to work with numbers we can say total current is never likely to exceed 0.2 Amp (200 mA). On the range I normally run mine on a 12 Volt 8.0 AH battery so we can figure in theory this thing could run about 40 hours continuous on a single battery charge and that includes motor running which is not the case".
So an everyday 12 Volt 8.0 AH (Amp Hour) battery would run the thing for about 40 hours and that is if the motor ran continuously. Also I really doubt weather a DC input voltage of 9, 10, or 12 volts matters. As I mentioned my unit came with a 9 volt 1 amp adapter but in comparison many came with 10 or 12 volt adapters. While I have had no reason to field strip my unit I will venture a guess here. My guess is that these units have an internal voltage regulator for the actual electronics. I could not find a good image of the board where the external DC enters. Maybe one day out of curiosity and boredom (these days) I'll take mine apart. Mine has never exhibited a drift problem so I have no reason to open its guts.
I found a 12 Volt 8.0 AH SLA battery fits nicely into a 30 Cal ammo can as well as a nice little "battery maintainer" which can be had for about $20 and up. I leave one on my bike during the winters. The connectors can be had on Amazon for under a buck a pair. Not much to it and pretty easily done. I would shove an inline fuse in there for good measure, just to be on the safe side. Besides I would have pangs of guilt if I didn't include that.

I tend to agree with you, the power supply that came with my charge master also states that it has an output voltage of 9 volts but is actually producing 12 volts according to my multi-tester and I have checked my multi-tester and know its accurate.From this older thread.

Have you checked your power supply, I wonder if it is producing out 12 volts like mine is.
