Fish care function, power outage

[JoeESSA]

Can someone describe to me how the fishcare function with Turbelle Streams works and what it does?

I'm thinking about getting 2x6000's with 7095 controller and I am looking for possibility of keeping the pumps running in the event of a power outage. What would be required to achieve this?

Finally, I'm assuming that 6000 sold on the US market works fine and at full power with 115V supply?

Fishcare is a feature that when the pump is off due to the foodtimer or interval program, it turns one rotation ever 20seconds to scare fish away from entering the pump.

They work on 115v and only a basic computer BackUPS power supply is required.

Do the Tunze Streams require a pure sine-wave UPS or will a modified sine (modified square) work? I know that my current SEIO 620's do not work well with modified sine....

 

[rvitko]

Not the 6000 and 6100, a Sine would be ideal but because it is converted to DC it isn't critical.

 

[JoeESSA]

Ahh, that's good news. I didn't know for sure that the pumps were DC motors, but suspected that they may be since they are controllable (6000, 6100, etc).

Do they have an external transformer? If, so what is the DC output voltage range? Would it be possible in a pinch to bypass the transformers and supply them directly with DC in the event of a power outage?

Thanks

The set up is a bit complicated, a 6000 works on 11V, the transformer is a complicated torroidal transformer with 2 hots and 1 neutral and its output is AC. Inside the driver a bridge rectifier converts that to DC.

 

[JoeESSA]

Hmm... If the output of the rectifier had been 12V and also assuming that the output of the rectifier is external or that there is an accessible DC input port to the pumps then I reckon you can guess where I was going with that line of thinking....Then again maybe I would get a good flow rate if I overdrove the pump, but then I would void my warranty I guess ...

I have a fairly cheap UPS (modified sine) that I can use - trouble is they don't last that long even with very low load since the inverter uses a lot of power even at low or no load. Other alternative is to try to hook up a car battery in parallel with the internal battery in the UPS...

 

[rvitko]

The pump is only 15W so if it will run a computer for even just 10 minutes it should run the pump for an hour.

 

[JoeESSA]

I'll give you a business idea. Make a compatable DC backup supply module for the Tunze Stream in the event of power outage. Now that would be nice...

I'll accept a check for giving you that idea

 

[rvitko]

We have already been working on it.

 

[JoeESSA]

I knew you would say that

Anyway thanks for the info...

Any idea when something like that would come on the retail market? It would be a great selling point. Months ago I had switched my plans for a closed loop to Streams just because of power consumption in general and during a power outage.

 

[rvitko]

For right now you can use a standard UPS system for computers. Anything we offer would be very similar, I cannot speculate on when it will be ready but I suspect it will not be for a year or so.
