Battery backup?

[rvitko]

A true DC pump has to be direct drive, magnetic drive pumps cannot work without some help from sophisticated electronics. The motor is getting DC voltage but it is not that simple, the electronics have a lot to do with how they work. The new pumps get DC power direct from the power supply and the electronics are in the motor itself, the old pumps get AC power from the transformer and AC is converted to DC and the required controls are within the driver. You cannot bypass the driver and supply DC power, the coils would energize but no rotation would be created.

Ok Roger. Thanks as usual for being so responsive. I'm using an 850w APC UPS now which is...ok...but doesn't last very long. I was looking for a better backup method. I guess I'll have to get a bigger UPS.

 

[sjm817]

Me again
I've been looking at UPS units and to get one that would run a 6100 for any length of time gets pretty spendy. I have one now, but I can only get a little over 1 hr out of it.

I'm thinking it would be more cost effective to replace one of my 6100s with a 6101 and a 6105 safety connector. I can sell the 6100 to offset the cost.

How big a battery for 6 hr or so of run time? I assume is is ok to mix a 6101 and a 6100 on a 7095 controller.

Thanks again.

 

[rvitko]

Yes, you can mix them. The 6101 on 12V uses about 12W, based on what users have reported from a 12AH battery on a 6055 I would expect the 6101 will run for 12-18hrs about on this same size battery.

 

[sjm817]

Wow. That is awesome. To get that amount of run time from a UPS would cost a ton. The 6101/6105 is the way to go.

BTW, 9 min to get a reply! Enough said.

Does anyone know how to wire these up to a gel battery like an optima? Which one would you prefer and how long would a 6101 last?

 

[sjm817]

I ordered the 6101 and 6105 today. Also curious about batteries. I dont think Gel Cell is necessary. Just any sealed battery like a maintenance free car battery will work? It will be in the stand under the tank. Since the battery will be seldomly used, is there any type that is better for use with very long standby times? I'm thinking of going with a large battery like a 32 AH or so.

 

[jamesdawson]

Sounds great,

Unfortunately I have already invested in four 6100s.

Roger, is there any way to convert 6100s to 6101s or any modifications to get 6100s to work with this new Tunze backup system?

Thanks,

James

 

[rvitko]

No, I don't know of any way to do it, I am sure it is possible but you would have to supply the power to the driver and it would be complicated. I will be in Germany in May and possibly I can get a solution on how it could be done.

 

[jamesdawson]

O.K, thanks Roger.

If you find out a way let us all know as I imagine there must be many thousands of reefers with the older units out there who could benefit from this.

I checked this out. I found a 12V 17AH Sealed Battery on Ebay for $39.58 shipped. I got a float charger from Harbor Frieght for $7.35. A few dollars for clips & wire got me to a total of less than $100 for a battery backup that will run for about 42 hours on my 6055.

 

[sjm817]

I ordered a 35 AH battery for $65. It should last 35 hr (?) in theory on a 6101, but I'm sure it will be less in real world, but more than enough for my needs.

 

[strictlySPS]

anybody have any wiring diagrams or pictures to show how to connect these batteries?

 

[wbeavers]

The first thing I would do is connect my battery to the charger. Then you connent the positive on the battery to the positive on the Safety Connector terminal block. Next you connect the negative terminal on the battery to the negative on the terminal block. The next step is to place your pump and attach any controller. Next you connect the Turbella pump to the Turbella pump jack on the safety Connector. At this point it should run on battery power. Plug the tranformer to the safety connector. The last step is to connect the AC power at the wall for both the Turbella, and your charger. The pump should switch from DC to AC power supply, when pluged into the wall. A small shutter in the pump would be experienced at that time.

I have it all hooked up and it works, but not quite in the manner I expected.

I expected that is was just a sort of relay cut over, and would bypass the 7095 and just run the pump at a steady rate off the 12V battery.

The first thing that was unexpected is that it didn't work (or didn't seem to). What I found is when it switches over, it goes into feed cycle, so there is no operation for a few minutes except for the brief pulse like normal in that mode.

The second thing I didn't expect is the controller still functions and the speed of the pump varies when on battery.

My 6101 is on channel 2, 6100 on channel 1. I run interval 2, so what I get when it is in battery backup is..

channel 2 active ... 30% - 100% - 30% - 100%........
channel 1 active ... 30%---------------------------

Roger, is this the way it is supposed to work?

Thanks

 

[rvitko]

The feed cycle being activated sounds unusual, I don't think that is supposed to happen but it would continue to pulse if used on a controller. The controller would continue to function.

Roger, I have (2) 6201's that I'd like to put on battery backup. I've read through this thread, but still confused as to *what* I need to buy to get up and running. My understanding is I need to buy the following:

(2) battery adaptors - 1 for each 6201
(2) car batteries - 1 for each 6201
(2) trickle chargers - 1 for each car battery, and to keep the car battery charged

Am I understanding this correctly?
Is the trickle charger necessary?
Also, once there's a power outage in our house, the car battery should power up the 6201's automatically? I don't need to be home to do anything, right?

Confused, but thanks!

 

[rvitko]

I would not use car batteries, I would use small sealed gel cell batteries like they use in Power Wheels or to back up your home alarm. Otherwise you are correct and it is an automatic switch over.

 

[tbone28]

Thanks Roger, I did read about the gel batteries, but thought those were car batteries. Do you know if these gel batteries leak fluid? I will have to place this battery on top of my kitchen cabinet, and can't have any leaking.

If I don't use a trickle charger, this gel battery will die on me eventually?
