Don Posted October 26, 2004 Share Posted October 26, 2004 Does anyone know where I can buy a male and female socapex bar tester (grenade) in the UK? I have found a female one but no male from Stagepoint.co.uk before anyone sudjests it, no I cant be bothered to make one, just to busy at the moment. Thanks in advance guys and girls.

Stu Posted October 26, 2004 Share Posted October 26, 2004 There has been a topic done on this somewhere in the Lighting part of the forum - try doing a search either using our search engine or within Google. Cheers,Stu Link to comment Share on other sites More sharing options...
MarcT Posted October 26, 2004 Share Posted October 26, 2004 As I understand it, the device will show if there's a bulb on the far end. It's just a socapex socket with LEDs wired in series with the lives to 9V & neutrals wired via a resistor to ground. add an LED on Earth & you can see blatant faults. Marc Edit: Should have read the OP more throughly. Anyway, its probably cheaper to make one than buy it... Link to comment Share on other sites More sharing options...

I guess it tells you if you have a dimmer rack connected ( shortly before it blows up) Link to comment Share on other sites More sharing options...
Don Posted October 26, 2004 Author Share Posted October 26, 2004 The male one will tell you if you rack is out putting all six channels or the soca is working, eg when up the truss you can check the continuity of the 6 lamp bar or what ever and also check the soca has all six ways connected. think it uses 240v LED's or some resistors of some sort. they are quite common just cant seem to find where to but them other than Stage point or TMB who sell stagepoints product. They only do the female one. Link to comment Share on other sites More sharing options...

TomLyall Posted October 27, 2004 Share Posted October 27, 2004 If its mains voltage its more than likely to be a neon, surely? Is this what your looking for? http://www.stagepoint.co.uk/Socapex_Grenade.htm Edit: okay sorry I see you wanted a male connector, and you've already talked about the one on stagepoint. Sorry.

That's what they were born to deal with. For AC use of LEDs, you do need to connect an ordinary diode in inverse parallel, since LEDs have a low maximum reverse voltage, but they're perfectly usable. Certainly preferable to lamps in Don's situation, since they should withstand the mechanical rigours better. Link to comment Share on other sites More sharing options...
j_b Posted October 28, 2004 Share Posted October 28, 2004 While we're at it, why not add a 120nF, 400V capacitor in series - to give you about 10mA limit to the current, without getting hot. Otherwise, you'd need about 24k, 2.5W resistor. Umm cant imagine LED's being to happy with AC being diodes and all. Maybey just a signal lamp.<{POST_SNAPBACK}> Diodes thrive on AC!
