Neptune Pmup control

I have a V1 Robotank and was wondering if it’d be possible to control a couple of Neptune PMUP pumps. Their plugs have a little retainer on them which I have no problem cutting off if it’ll work. It looks like they are 24v so I’m guessing not but thought I’d ask. Also, I apologize for a couple questions about Neptune equipment. I bought a tank that had an apex and I want to sell the apex and use robotank but there are a few accessories I’d like to be able to use if possible.

No worries, it would be great if you could use some of the Apex controller. If those pumps just need 24v to power them and turning on/off is enough you could connect it to a DC port. You can power the controller with 24v and the DC ports will also be 24v. Of course if you have any 12v devices connected you would have a problem there but you could always add a DC step down regulator so they only put out 12v for those devices.

I plugged in a 24v 3A power supply to the v1 and it started smoking. I’m pretty sure that wasn’t supposed to happen. Got to pull it apart to see what fried.

Oh no, I'm so sorry, I feel horrible. I forgot that the AP3513 is only good for max 18v. Now that part is obsolete, I've been searching for a replacement with the same pinout but can't find one. Looks like I'll have to send you a new controller but I currently don't have any, it'll be about 2 weeks until I do. :cry: I'm so sorry about this...

Again I'm very sorry about this, I really screwed up. If your able here's something that should get you going again until I can get you a new controller. Let me know what this costs you and I'll send some funds via Paypal.
  1. With a utility knife cut the trace going to F1 fuse, that's the red line just above F1 Make the cut nice and deep, you can cut it in several places to insure it's not connected.
  2. Solder some wires from a 12v DC regulator. The +5v output goes to the fuse and you can connect the ground to the DC barrel input on side.
Here's a link to a 12v to 5v regulator.

You'll still need to plug in your 12v power supply on the barrel connector to power the DC ports. The burnt IC should be ok left on the board but if you need to remove it here's a video showing an easy method.
