Jebao Questions

[mjlash22]

Two questions for any Jebao users out there.

1. Had a DCT-4000 on my reefer 250. It's the second one in 2 years and this one is having the same issues as my old one. It just keeps seizing up. You can hear it trying to turn over but it ends up giving the error message blinking lights on the DC controller. I'm assuming it's either an issue with the magnet or with the ceramic rod/bushing. Does anyone know a work around/fix. I've taken the thing apart several times to clean it with no luck.

2. I'm in the process of building a reefer 525XL and purchased the DCP-10000 for that tank. Due to the fact that I couldn't get the DCT to work, I had to plumb this one into my reefer 250 temporarily. Question I have is this DC controller is a lot different than the DCT line. It displays in watts and power vs the 10 lights on the DCT controller. When you hit the up or down buttons it changes to "P" and then a number. When you have selected your number it changes to "W" and a lower number. Can someone easily summarize how this controller actually works since the instructions are far from adequate. I want to make sure I have a good flow in the 250 until I can swap it out with a proper size pump.

The P number is the percentage of power I believe. 0-100 The W is watts being consumed. The screen that displays after touching buttons should be the watts being used screen.
My controller is DCP sine wave. On my controller its P first which is watts. When I hit arrows I get "F" The watts are about 5 more than display indicates. Maybe yours is a bit newer and they fixed it.

I have a 450 with a DCP 10k. With 1 inch pipe to a non stock 1 inch by 3/4 threaded barb into stock reefer plumbing I am getting 320 GPH at 40 watts consumption. I recently changed it to 1-1/4 pipe to 1 inch slip x 3/4 thread to stock reefer plumbing and picked up 25gph at same wattage. Use the 1-1/4 on yours if possible, especially if building a manifold.

Right. I believe you are correct and I am reading the same thing in regards to P = power and F = watts. However I can say that the P only displays once I start hitting the up or down arrows. The F then displays after about a second or so after I have selected the P.

In assuming a scenario in which there is no head pressure and that the rated flow for this pump is 2642g at 100% utilization (manufacturers rating), can one assume that 100% power is the full flow rate? From my tinkering, it seems that really the only thing you can control is the power and then it displays the wattage afterwards instead of the power. A little misleading as they advertise this pump as controlling through the wattage, where it seems you still control the power and then it tells you what wattage you're using.

I’ve always had better luck with dc pumps by replacing the power supply with one of a much higher amperage.

Any recommendations/brands?

Not really no. I just went with decent priced ones.
Basically looked at the stock supply , and went 4x or higher. I’d assume you need a 5-10amp for that one.


I also eliminated extra power supplies for the powerheads by using a splitter.

A fwiw , I’ve gotten and/or had supplies the same amperage as the stock oem ones , but were twice as big or heavy. And worked better.

Appreciate the info! Will look into this to possibly salvage one of my DCT pumps.
