Profilux II plus aquarium controller

[Matthias Gross]

niloc16, thanks for the detailled information. I think i'm sure about what's happening. The extremely high inrush current heats up the relay contacts at the moment of closing. Then they are "glued" and can't open when they should open. Another impulse (permanent on/off) jiggles the contacts and they are again free.
Why does this happen now in Canada while in Europa not even one of several thousand powerbars has this problems?
Probably the inrush current is 2x higher as in Europa because the coils resistance is only the half (you have only 110V, we have 230V).
The problem could be solved with inrush current limiters which are integrated in the powerbars. The disadvantage of these limiters would be that you could "only" get 8A permanent current out of a socket which is protected by an limiter.

My question:
Is it OK to have sockets with full power (15A) but not beeing suitable for inductive loads AND sockets for inductive loads (with high inrush current) at 8A?
I thought about the new digital 6plug powerbar we just started to produce: 4 x 8A + 2 x 15A (of course in sum only 15A because your household can only deliever 15A).
Would this be OK? Or any other suggestions?
@jrm99: Thanks a lot for your commendation and your information about the "switching problem". As you can read above i think we found the reason and we will solve it soon.

i have 4 250w MH plugged into one clock timer outlet and yet it has never stuck.now why would flouresent lights do that when they dont have a start up surge.

Besides that everything else is working mint and the Tunzes I hooked up are sweeeet.So many current settings!!!


ITS A NICE!

The Lights I had the problem with staying on were also Power Compact florecents no problems with my any of the 3 250 watt MH. For now the problem seams to of corrected it self it hasnt done it for a few days now

Fluorescent do have ballasts and they cause a start up surge.
But usually this surge peak is not high enough to damage anything.
Can you please tell me the ballast type?

Switching of electronic ballasts (as for the T5 and T8) made never before a problem. We produce dimmable lighting units which include relays for switching on/off the lamps. Last year we sold about 1500 dimmable lamps and we never had a problem with a defective relay. So i wonder what the difference is in your cases. We use only Osram (in USA/CD: Sylvania) ballast in our lamps.

Thank you for all your support in our forum.
I am really puzzeled myself as the units that we used have never acted up this way.
I am not sure what the problem is but not everyone is experiencing this ,I think it might be a problem with install & or setting choice.
I am going to also ask Marc tomorrow in regards to this as well.
I know he has 3 powerbars & they are all operational.
I will keep you posted

Matthias,

Will the firmware 3.00 be available by February? Also, could you give me any more details in regards to the new dosing funtionality included in the 3.00 release?

Thanks in advance for your assistance,

If it was the programing the LED indicator would not go out it would stay on to indicate that the outlet still has power I dont know about every one else but on mine the LED goes out. am sure we will come up with a solution sooner or later

the led goes out on mine as well even though the lighting is still on. so it cant be a programming issue because the controller has sent a signal to the powerbar which opens the relay and turns off the led. when i do fix it, i can hear the relay close again. it has happened with metal halides and t5's. i've heard today that when other controllers first came out and released in north america there was similiar issues with the power bars. i'm assuming it has something to do with the conversion to 110v

@mnsps:
The firmware will be available this month, the new ProfiLux shipped to Proline will allready have the 3.00

Firmware 3.00 will have some new controlling features.
Besides the standard controlling mode (switching with hysteresis) we added new modes. Now are proportional controllers available with adjustable pulse/pause times.
It is too much and too complicated to explain this detailled here so please have a look to the new manual - we added some pages in it! The translation will be available soon, i will post when the download is possible.

[niloc16]

so can we trade in our old power bars for the new ones? i apologize for not knowing electrical theory well but if these new bars with ILC will only carry 8A each continous will that still power 400w halides? why is it a disadvantage to only have 8A per outlet?
