led controller

[Blahenazo]

Hello,

So it seems this thing would be analog 0-10v => pwm converting device
http://www.pacific-sun.eu/index.php?option=com_content&view=article&id=49:ghl-controller-for-pacific-sun-lamps-released&catid=1:latest-news

1 question , in the data sheet it says also thunderstorm , I thought the L ports where to slow ??? of is this different with led lamps ?

any change this will come as a PAB device ? ( I need to conserve my L ports :) )

[Matthias]

yes, the 1-10V-signals are too slow for a flash

but a special trick in the 1-10V-PWM-converter makes it possible

PAB - no plans yet

Do we know if the PWM capable meanwell drivers (ELN-60-48P) will support lightning using this module?

Yes, it´s still said ... between the lines .....


yes, the 1-10V-signals are too slow for a flash [so normal 1-10V devices are not able to flash]
but a special trick in the 1-10V-PWM-converter [inside the GHL devices] makes it possible [for the GHL devices like the SIMU-L]

[Blahenazo]

it does seem to be a 'passive' module so if we are still limited by the 10 mA of the L ports , it will be even less efficient then the normal L ports ( if you loose some efficiency in the convertion)

OR are we not longer limited to the 10 mA limit of the L port ?

yes - when the LED-Controller recognizes a "flash" over the L-ports it will change the PWM duty cycle to 100% for some miliseconds - there is your flash

there will be 2 variants of the LEDControl4: passive (switching only some mA, enough for a PWM controllable driver like Meanwell) and an active version with MOSFETs in it, able to switch 2A

technical details will be announced soon

This is great news, thanks Matthias for another fantastic accessory.

We have lots of users over here that are itching to see this unit in the market. Sure makes ProfiLux the #1 choice for DIY lamp builders :)

Hail to GHL ! :)

[wrang]

wow great news that the new LEDControl will work with PWM :)
No i can plan to build my LED light

When will the new LEDControl4 came out to the market

[aqua_digital]

For the NA market I am expecting about 6 weeks (subject to change of course)

[wrang]

GHL - ProfiLux LED Control 4 (http://reefbuilders.com/2011/02/01/profilux-led-control-4/)
How does it works. Is it possble to have 4 diffrent channels?

[GHL Support]

We kindly ask you for some more patience - more details will follow quite soon...

I am sure GHL will follow shortly with a more comprehensive and official launch info. But hope this answers most things for now and reduces my inbox stress ;)

[wrang]

Great news!!
But i cant find where it says how many leds eatch channel can have as minimum. I think about the active unit
(
LEDControl4Active - with integrated drivers)
Is it possible to have one 3watt led on one channel

[wrang]

Asked again. Someone ho knows

[Matthias]

this depends on the power source you are using

LEDControl4Active doesn't include a constant current controller!

it just switches the conenction between used power supply and LED on and off (PWM)

usually you should use the LEDControl4Active only for LEDs which are built for a constant voltage, not for a constant current!

[wrang]

Sorry but I can not really know what you mean. I want to build an LED ramp and to dimming the Cree 3w diodes, it is better to get a LEDControl4 passive unit?

[Matthias]

first of all - you should be aware that some basic knowledge about electronics is necessary for a DIY project like building your own LED lamp, otherwise you will damage LEDs, ProfiLux and accessories! this can become easily an expensive excercise!

I think it is easier to make a LED-lamp with ready-to-use LED-drivers, e.g. from Meanwell with PWM input, they can be connected via LEDControlPassive with the ProfiLux
I guess you have now detailled questions about this, then please open a new thread in our new forum section

[marco]

will it be, in the nearby futere. Possible to dim led tubes with the LEDControl4Active ?

[GHL Support]

"LED tubes" is far too general to could give an answer.

How they are working? Power consumption? Do they work with a delivered power supply?

there you got a point

for example led tubes whit this specs

the data from the LED tube are

Replacement for fluorescent tube 150cm 58 watt
Number of LEDs: 420
Fitting size: G13
Lamp Size: L.1500mmx? 30mm
Consumption: 18 watts.
Voltage: 220 to 240 volts.
Degrees angle: 120?
Light color: warm white (3000 - 3500K)
Place in existing luminaire after removal USA and starter
Burn Times:? 50,000
Warranty: 2 years.

[Wirus]

Voltage: 220 to 240 volts.

Tubes with that voltage cannot be used without modifications.

If it has an external driver module, it may be possible to in between the cable from driver to tube. If it´s possible or not depends on technique the driver is using (constant voltage: possible; constant current: impossible) and the used voltage

If it has no external driver module (=build-in one), it is very difficult due you have to modify the tube.

In any case it´s a DIY solution and general electric knowledge is mandatory.

[GHL Support]

Wirus is right. Without a control interface it isn't possible. The usable voltage for LEDControl4 active is up to 18V DC

[marco]

thank's for the reply.

what kind of dimmable led can be used in combination with the profilux?
it's for a fresh water tank
