neilalexrose Posted April 22, 2010 Share Posted April 22, 2010 Does anyone know the minimum outputs of my chilli dimmers ? 1% ? Manual here Quick read of a spec sheet gave me a figure of 0.1A. not necessarily the model you've got though. Read the links on the website. what do you actually mean? Minimum current output, minimum voltage output, smallest wattage bulb you can plug in and not light up on residual current? Or do you want to know what residual current it kicks out? Touch more clarification please. Neil Link to comment Share on other sites More sharing options...
"qui que ?" Posted April 22, 2010 Author Share Posted April 22, 2010 hello. great to hear from you. I'm looking for minimum V & W .. this device for example ... Operating Range 1.5V-5.5VNominal 4.0 VCurrent (A) 0.035 A Typical Load Characterisitcs Current(A) 0.12 AOutput (W) 0.197 Stall Condition Current (A) 0.34 thanks again Link to comment Share on other sites More sharing options...

What are you thinking of plugging into a dimmer output? Dimmers are 230/240v in this country, and designed to dim tungsten filament lamps. The 'device' you describe above looks like it requires a transformer. If it is a 'device' that will dim in the first place, then you will need a transformer that is also able to dim. Again, what are you trying to plug in? Link to comment Share on other sites More sharing options...
Jivemaster Posted April 22, 2010 Share Posted April 22, 2010 Do remember that a dimmer is NOT a variable voltage power supply, it's a (usually) phase angle chopped mains sine wave. If your "device" has a stall current, it's a motor, why are you trying to run a 4v motor off a 240 dimmer? Something(s) may go bang and it might be a whole dimmer pack.

"qui que ?" Posted April 22, 2010 Author Share Posted April 22, 2010 I was worried about that. ever come across DMX transformer packs ? =) A concurrent post has been automatically merged from this point on. they are still single phase right ? many thanks all !

sleah Posted April 22, 2010 Share Posted April 22, 2010 <intrigued>Wots a DMX transformer pack then Mister? Never 'eard of dem </intrigued> Link to comment Share on other sites More sharing options...
"qui que ?" Posted April 22, 2010 Author Share Posted April 22, 2010 nah me either.just figured it would be able to use a DMX controller to control different smaller outputs.. might be better pursuing new media here.. mm. ever interfaced midi with the digital lighting desk ?

Brian Posted April 22, 2010 Share Posted April 22, 2010 So what *EXACTLY* are you trying to do? It looks like you want to take a DMX signal and control a non-mains voltage? Correct? If so, AC or DC? How many volts max? Link to comment Share on other sites More sharing options...

DonkiDonki Posted April 22, 2010 Share Posted April 22, 2010 just looking for a light weight electric pulley thing really. I've just been looking for some DMX stuff myself and found thisDMX doo-daa peoplemaybe there is something there which will help? Link to comment Share on other sites More sharing options...
"qui que ?" Posted April 22, 2010 Author Share Posted April 22, 2010 couldn't go far wrong with a doo-daa Link to comment Share on other sites More sharing options...
musht Posted April 23, 2010 Share Posted April 23, 2010 Brutalise a cheap LED Par, guessing its a D.C. motor so a PWM drive is what your after, coincidentally similar to LED drive, might need to beef up the output devices and seperate supply to get output down to 6V or so for motor, sart and on load current might be bit higher than nominal, relay with pull in close to DMX255 for reverse.

With a couple of doo-daa's, wink-wonks, thingamebobs and some electronics tinkering it should be possible to control near enough anything with DMX, with the exception of safety critical applications such as flame devices, as discussed elsewhere in the forum.Personally I wouldn't suggest butchering a cheap fixture as suggested for what the OP seems to be trying to achieve. It would be better to start with a kit such as the Milford range and adding to that, it will be easier and all the information you require regarding outputs, voltages, currents, control protocol and so on are included with the kit. Much of it would be pure guess work with an existing device. And yes, it is quite possible to interface a DMX desk with midi, not uncommon either B-) The data can go in either direction too :D Link to comment Share on other sites More sharing options...
dmxtothemax Posted April 23, 2010 Share Posted April 23, 2010 Does any one know what the hell any of them are talking about?I still dont know what info he wants,Or what he is trying to do! Link to comment Share on other sites More sharing options...
