Does this unit have a setting for constant current operation? I would use this for anodizing and need constant amperage, allowing the voltage to vary

No. The voltage is the only thing adjustable. Amps only respond to load. It will hold a constant VOLTAGE.

I am also using this power supply to anodize copper etching plates with iron. The bath contains a high concentration of ammonium chloride and is therefore highly conductive. I am not able to do any significant adjustment, but the amperage (8-10) is sufficient to do the plating even though the voltage is very low. If the bath is less highly conductive, adjustments should be possible...

I am also unable to adjust amperage. I notice that amperage changes with voltage but I cannot adjust current(amps) alone. When I turn the adjustment screw on the right nothing happenes....If u can figure it out please let me know. Thanks -Mike

I finally found the current requirement for the unit. The barely visible label says 1.8 amps at 120 volts. I hope that this helps.

Hello,The unit we are using runs on batteries, so there is NO issue with electrical currents.Enjoy.

Has the two settings 5 or 10 amp.5 is for a slow charge.I used it to charge my 6 batteries in my lowrider for the hydraulics.worked great every time.start charging them in the evening and let it charge overnight and by morning i was ready to hit the switches.well worth the money.

Well, current will depend on the draw of what you are connecting it to. you could put an inline resistor if needed. To control the voltage, you just turn the pot screw until the meter reads the voltage you want. you could do 12 or 18 volts with a turn of the screw driver. basically, this should do exactly what you want.

I took a look at all the paperwork and packaging that came with the unit, and the current (amperage) was not indicated anywhere on the unit. However these units work off of high voltage (17,000,... V indicated on the box) and very low current (In the 1-4 milliamps range, or .001 -.004A .) remember 1 amp can kill a person, and .01 amps can severely hurt or burn you.

The unit I got was preset to 11.99 volts output. I used a voltmeter to set it to 12V output. The input accepts a range of voltage and does not need to be set. I connected my 20V and then 12V rechargeable batteries and the output voltage did not waiver.

Hang on while I go look. There is a tag on the bottom that states 120V A. C., 60 Hz., 1.5 A. I would have guessed it would have a higher amperage need. Additionally, there is no mention of voltage or amperage requirements in the Owner's Guide.

Steve, I just discovered the adjustment pot for zeroing (or at least get it close to spec) the DC clamp current. Turn the meter over, then open and remove the battery cover. On the back you will find two holes to the left of the center chassis screw. The hole closest to that center chassis screw locates the adjustment pot for the DC clamp current mode. Turn the pot clockwise to decrease the value towards negative, counter-clockwise to increase the value towards positive. Use a miniature Phillips #1 (3mm shaft) screwdriver. See the photo I uploaded.

NO. this does not draw enough amperage. Hooked mine up with a 20A switch with a 10A fuse. Works great.

Mine runs all the time but does have a constant load on it of about 5 amps. Have had no problems with it and plan to buy another.

I'm not really sure what you're asking, but this device is only capable of raising voltage. If what you mean is that your 12 volt system is rated to say 5 amps and you want 10, no, this cannot do that. In fact, this can only LOWER current while RAISING voltage (remember, P=IV and V=IR).

No adjustment available on this unit. You might consider installing a current limiting resistor on the output. Great unit with such a wide range of input I use it with a solar panel and packs of spent alkaline batteries for phone charging.

I don't recall. Check with www.Rolls.com for details. I use a Voodoo Labs pedal power unit to provide the voltage. It works with 9-15 volts DC.

It adjusts to a lower voltage but I think the amperage stays the same, about 1-1.5 amps....

If this is arc welding, then a higher voltage would allow a smaller tip. Most laboratory power supplies have a current limiting setting (left set of knobs). When operating in constant current mode, the supply will adjust it's voltage to whatever is needed to maintain that current. If that voltage is close to zero (due to short circuit), the current will still flow at the limit setting. If you max out the current limit setting to 3A, and the resistance is not too low, the supply can offer up to 30 volts (90 Watts max).
