6105 wattage, Safety connector on controllers?

[James77]

I threw both my new 6105s on a killawatt, and one reads 22 watts at 18v, the other reads 16 watts at 18v with noticeably less force in the flow. This is with both potentiometers turned up all the way.
edit- same thin when I switched transformers, I'm going t swap drive units.

To run on battery- am I figuring right- amp= watts/volts- which is what these will draw?

Also, what happens to the streams on controllers- either Tunzes or a 3rd party like Apex- when the power goes out? Do the controller keep running them?

Hmm. switched drive units, now one drives at 21, the other at 20- both with similar force. Kind of solved itself

Your KillOWatt may be a bit off or the speed may be turned down at the connector or on the controller as a 6105 usually will use 26-28W at full power at 18V and at 12V it will usually use 10-12W. I typically figure on 1 hr per Amp hour of battery life. I don't recall the specifics but Ah is based on very specific load ratings and draw down times and a lighter load results in a lower rating as power is lost to just chemical reactions in the battery. For example if you use a 7Ah battery you can be sure to get 7 hours if the battery is in good condition and very likely when new you will get 8-10 but I wouldn't 100% count on that. It is not uncommon for cheaper watt meters to be off, we use a KillOWatt here for a quick and dirty test but if there is any question about the result we use a Watts Up Pro which typically reads a couple watts higher and can also be zeroed out unlike the KillOWatt which sometimes reads -1 or 2W with no load at all.

Regarding the Apex. I cannot give a definitive answer, if your controller has to be plugged into work, the pumps won't work if the controller cuts off unless you disconnect the controller. Our controllers are powered by the pumps so if the pumps work, the controller works and it has no effect except on a 7095 or 7091 occasionally the foodtimer will engage during the brief blip in power, then 5-10 minutes later the pumps come back on after the foodtimer runs down.
