6105 power supply issue also

[sammie]

I just hooked up my 6105 to my apex and have it programmed from an example in the Neptune forum and has been running for about a month. Then it stopped running and I determined by trying my other 6105's power supplies that the power supply has died. Is there any relation to having the 6105 controlled by an apex, and I don't have it going lower than 30%, that would make the power supply die? I don't know exactly how old this unit is but I've had it for about 2 years.

Also I've ordered a replacement power supply because I need the circulation back ASAP so how long will it take to get????

We have your order and it will ship tomorrow, I expect you will get it by Tuesday at the latest.

It is hard to say, I cannot think of a way this could happen but I had a local maintenance company swear that the brand of controller they were using was killing our power supplies. It was a European brand and they said every single pump or wavebox they connected had a wiped out power supply within months. I can't see why this would happen unless the controller cable had a short and even then it is hard to imagine the link and I have never heard of a Neptune doing this. I would probably chalk this up to a coincidence, the power supplies do tend to fail at 3-4 years old.

Thanks Roger. I also have 2 6205's running on the same apex running the same program so we'll watch to see if they fail. Haven't so far and have been running the same length of time as the 6105.

They should be about 180, the 6105 power supply would have a very short life. I may have a good used one, I am not in the office until Monday, but please call me Monday.5128337546

I can't comment on your particular problem but can give feedback on my experience to date. I have been running two Tunze 6055 pumps via the variable rate outputs on my Apex for over a year. No problems at all, rock solid. I have various profiles set throughout the day.

The 6205 power supply is much more robust, in fact we almost never see them fail. Since the pump is using only about half of what the power supply can deliver, it runs cool and lasts longer, these big power supplies are very expensive and that is why the bigger pumps cost so much more. The 6105, 6095 and 6055 use about 2/3rds of what the power supply can deliver so they are pushed harder and these issues tend to correspond with peaks where the pump is dirty and may use almost all the power the power supply can muster so they overheat. In general the way to get the most out of the power supplies is keep them below 80F and 70% humidity and keep the pumps clean.
