Meanwell 12v 350w enclosed unit/What size flex

[LEEBOY]

Hi Guys & Girls,
i have an enclosed Meanwell LRS-350 12V switching power supply and to get it up and running ,3 core flex has to be connected direct to the unit{bare wire} and the other end a 3 pin uk mains plug.

So my question is as follows what size 3 core flex should i use to connect it all up.
Any info will be very much appreciated .
Kind Regards Discoeye

Hi,
took your advice and got the cable. I have a question can i use crimp connectors on the N/E/L ends to get a better connection on the screw terminals on the meanwell and if so what sort ,

Thanks ever so much

post a pic of the terminals. i'm concerned about the 12V side @ 350watts, thats just under 30A, so something like 6.0mm cable on that side, esp if the cables are a fair length. volt drop could be a problem.

Hi,
thanks for the reply. Got some pics for you. cable from power terminals to 3 pin plug will only be 12 inches.

regards leeboy

the 240V coable will not be a problem 0.75 mm flex with a plug fused @ 5A. insulated ring lugs for the connections into the unit. 4mm or 5mm hole?

 

[LEEBOY]

Hi,
website states m3.5 screws.

regards leeboy

 

[telectrix]

if the terminal screws are 3.5mm then your ring lugs need to be 4.0mm holes, with the cable enrty sized for the conductor csa. e.g. red for 1.0mm/1.5mm.

Hi,
many thanks for all your help its very much appreciated.

kind regards leeboy

 

[telectrix]

on the 12V side i'd use some 2.5mm tri rated .

 

[LEEBOY]

Hi,
thanks for all your help. With the m4 lugs how do i determine the cable entry size from 0.75 flex.
thanks ever so much leeboy
