Serge PS2A question

Post by vegas7188 » Fri Feb 27, 2015 8:53 am

Hi all,

I have an Animal in a shallow boat and a Serge PSA2 powering it. I was just wondering how people tend to have the power distribution part, at the moment as i use the Animal just on my desk, the PSD just hangs off the back of the desk, and attaches to the power supply like that, which i feel is slightly inelegant. Also how safe is it to do this? Is it okay to touch the PSD while it is on?

At first i would disconnect the power supply from the PSD for storage, but the little connectors are quite stiff/not very easy to disconnect and was worried about damaging the PSD by yanking them to hard and they don't seemed designed to be regularly connected and disconnected like this.

So i guess i am asking is how do you guys deal with yours? i suppose its relatively unusual to just have one panel, and to move it around a bit, rather than have it stored in a fixed location (unfortunately i don't have room for this so need to store it elsewhere from where i use it).

Thanks
David

You are right to be concerned.
Those cheap Molex connectors are designed for internal use only and are not meant to be regularly disconnected/connected.
It is OK touch the PSD while on but protect it from contact with something that could short it,metal or liquids for example

If you're just planning on having the one panel, you don't need a PSD. Just make up (or have one of us make up) a cable that goes 5 pin XLR (Rex's 'standard') to 4 pin Molex (Rex's other 'standard'). Always leave the Molex cable plugged in and use the XLR for connection/disconnection. They're designed for that purpose, unlike the Molex.

If you ever expand your system, it's worthwhile to consider a Random*Source PSU, as it uses 4 pin XLR (Ralf's 'standard'). There's 5 of them per PSU so you don't have to worry about a PSD. Just make up a bunch of 4 pin XLR to Molex cables.

Be aware that this wire is larger than the maximum that the XLR plug is designed for. You'll need to enlarge the rubber boot of the XLR as well as clip off some of the internal strain relief just to make it fit. That being said, it's extra size and robustness make it an excellent choice.

You'll also want a male Molex shroud:

Mouser # 571-7700751

with female pins:

Mouser # 571-7701461

The XLR needs to be 5 pin female:

Mouser # 568-NC5FXX-B (as one example)

Cheers,

Stephen
