6025 and Battery Backup

[Zentoolie]

Hi,
I'm trying to use a 6025 Nanostream with a battery backup using an APC Back-UPS ES-700. When the power is cut and the battery kicks in the Nanostream stops. It stops when it is the only component plugged in to the UPS and also when a small fan is plugged in (the small fan works), so the battery is functioning. Any ideas anyone? Thanks in advance.

It's the UPS....

A lot of UPS systems only put out 110v instead of 120v, and the sine wave might be less than ideal as well and not be a true 60hz, which gives the pump fits. I've had quiet a few pumps that wont run on a UPS, only the larger external ones seem to not mind.

A 6055 will run fine on any UPS since it has a transformer and runs off DC instead of AC.

Once your UPS kicks over to battery, you could try unplugging and plugging the nanostream back in to see if it will jump start it. Sometimes that would get them going for me.

Thanks for the info. I'm in Australia so our power is 240V but I've spoken to a friend who is in electronics and he also has mentioned that the wave which is a square wave output by the battery could be the issue.

you need a "smart" series ups from APC to run most small motors
It is a square wave on most of the less expensive units but the smart-ups series uses a stepped square wave which approximates a real sine wave current flow and can drive small motors like the ac tunzes. Larger motors have enough inertia to overcome the square/sine wave issue.
