boranbasar Posted October 30, 2006 Share Posted October 30, 2006 Hello,We have purchased two Lite-Puter 1230 today. The Harting Connectors are mostly used in Turkey. We're going to use harting connectors, because they're cheaper than Socapex and easy to find in Turkey. We're going to use PAR64(1 KW) with these dimmers. In it's manual they told one channel can give max 30A output. In this case;P=I.V P=30.220 P=6600W Can we plug 6 PAR64 to one channel?? PS:Excuse me for my bad english.

Tourbus Posted October 30, 2006 Share Posted October 30, 2006 There must be an instruction telling you the maximum Ampage per channel? My guess is that the 30A is over the whole unit. I am not myself familiar with the unit, but can you check and see what the channel fuses are? This will obviously give you the answer. A Par 64 CP62 (1KW) pulls 4.2A, but I would allow 5A per can. Your English is better than my Turkish and probably my English too! Link to comment Share on other sites More sharing options...
pritch Posted October 30, 2006 Share Posted October 30, 2006 If the details on the website are correct, then yes, you can! Obviously you'd need to ensure that whatever cabling and connectors you've got feeding the parcans are up to the task. http://www.liteputer.com.tw/product.asp?id...;pid=1&p=4# According to the website, you can use 30A per channel, and it'll do that across all 12 channels, if you've got a large enough supply feeding the rack.

dbuckley Posted October 30, 2006 Share Posted October 30, 2006 Found some blurb with a google, and yes, the model 1230 is twelve channels at 30A. Thats one hell of a dimmer!!! To feed it fully will take a three phase 125A connector... Link to comment Share on other sites More sharing options...
Dj Dunc Posted October 30, 2006 Share Posted October 30, 2006 Thats wot 72 par cans from that one dimmer? how much saving do I need to do? dunc Link to comment Share on other sites More sharing options...
boranbasar Posted October 30, 2006 Author Share Posted October 30, 2006 Now I looked at our dimmers and their DX-1220 not DX-1230.And they give 20A output per channel and I learned the formula,P=V.I isn't correct.It should be P=V.I.cosfi (cosfi generally taken 0.85)Then our dimmers gives(per channel) P=220.20.0.85 = 3740 Watts. This means we can plug 3 Par64 cans per channel.And I want to ask another two questions.For 20A, which cable diameter should I choose(is there a formula or table shows this)? And how is the standart for Harting connector(using 6 Pars at one bar)? Link to comment Share on other sites More sharing options...
Ynot Posted October 30, 2006 Share Posted October 30, 2006 Boran, hi Welcome to the Blue Room. The things you need to consider are:Correct rating for the output channels - a good rule of thumb using P=IV is going to be more than accurate enough for calculating dimmer loads. I've got something at the back of my addled brain about an addendum to the formula, but not for resistive loads - I suspect the modified formula you quote may be for inductive loads.... Adequate supply - you can only pull from a dimmer channel what you feed IN to it, so the supply must be enough to cope with the load - and most importantly the cable must be rated to cater for the resultant current. Similarly the cable sizing for the load on each channel as well as the max rating for the Harting plugs/sockets. To be able to power six Par 64's, you're going to need 32A rated cable, and trying to get that in a multicore is going to be pretty darned tricky!! (Not to mention VERY heavyand stiff over long distances!!) Most standard Harting multicores tend to be rated at 10A max, and the size of cable that produces can be cumbersome to work with. I personally wouldn't like to try a 6-way multi at 32A! (IIRC 32A is 6mm sq, but don't quote me unless someone better qualified agrees!!) Link to comment Share on other sites More sharing options...
boranbasar Posted October 30, 2006 Author Share Posted October 30, 2006 Hmm. Ynot thanks for your reply. I have to use multicore cables, because we are going to use them for touring. We use Harting connectors that produced by Metesan(a Turkish company) At their webpage they rated 16A max. When I used 3 Parcans per channel, it should be 16A?? Then, I should still use 6mm sq cable for each? We hire a generator van for lighting, can give 250 kw. And we're going to supply dimmers with powerlock connectors.

Then, I should still use 6mm sq cable for each? We hire a generator van for lighting, can give 250 kw. And we're going to supply dimmers with powerlock connectors.From the Lighting FAQ, the rating for cable size is as follows:13A or 15A TRS - 1.5mm/sq 16A TRS - 2.5mm/sq 32A TRS - 6.0mm/sq 63A TRS - 10.0mm/sq So your 16A Harting cables should therefore be 2.5mm if in a single TRS - I'm not 100% sure, but I would suspect that 2.5mm should be OK in a multi-core - BUT I would check witha qualified (preferably theatre based) electrician before following that path. If you restrict your load to 3 x Par 64, then at 220v, the overall current draw will be just under 14A, which leaves you a little headroom. I would NOT advocate risking a fourth!!

David A Posted October 31, 2006 Share Posted October 31, 2006 I have some lite-puter 1220 units and they have an unusual rating system.You will notice that they have 25 amp breakers. they are rated at 25A for up to 30 mins or 20A 'for many hours'[if its used for theatre] or 12A in continuous use as in hotels.Don't ask me why.So if you will be leaving the lights up for long periods 3 per channel is safest but if you are alternating circuits a lot 4 per channel would be safe enough.The fans can be pretty noisy so I'd be inclined to put them somewhere isolated[the fans only kick in when hot] Link to comment Share on other sites More sharing options...

Or am I being paranoid.....? Link to comment Share on other sites More sharing options...

paulears Posted October 31, 2006 Share Posted October 31, 2006 Don't forget that touring with hartings in europe can be awkward. The UK pin connection is different from Germany (DIN 15565-8), used in most of Europe. Connecting anything to British wired Hartings can be dodgy - the DIN wiring having live on 7 and 8 which we normally use as earth. Stay away from UK sourced kit and you should be fine.

boranbasar Posted October 31, 2006 Author Share Posted October 31, 2006 Is the connection described at pinned topic right? 1-2-3-4-5-6 Live 9-10-11-12-13-14 Neutral7-8-15-16 Earth ? Link to comment Share on other sites More sharing options...
