Monitor Power

[rossibIT]

Morning,

 

I am just wondering if anyone is finding out (the hard way) that a monitor power source is no longer using kettle leads but changing to a small round din power cable (might be wrong, but hopefully you get an idea) .... does anyone know why this is happening?

 

We have classrooms that are setup for 2 computers using a double kettle lead on both so would mean a massive headache to accommodate the new power source. I have started to research and you can buy splitters but just wondering if these would provide enough power from the adapter supplied.

 

Just wondering thoughts on this.

Depends on the monitors you buy, the ones that tend to use a barrel connector tend to have the power brick externally (then plug kettle into the brick)

 

Weirdest one i've had recently is monitors with a clover leaf plug! Even the supplier didn't know as they sent them with kettle leads.

I don't buy monitors that don't use kettle leads. External power bricks are one more thing to go wrong/get unplugged/damaged/etc

All our monitors are HannsPree/HannsG and we're careful to check/specify that they are the models with built-in C13 (kettle lead) sockets rather than external power bricks. There were still plenty of options last time we bought, but agree it's an increasing issue.

C13 to C5 (and visa-versa) adapters are available, and you can go from C13 to C7 but only this way as the C7 doesn't carry earth.

 

If using an adapter, I'd invest in some adhesive lined heatshrink to bond them together at least semi-permanently.

For places we have separate monitors with power bricks, I've tended to stick the power brick to the back of the monitor with Sugru silicone putty, keeping them together:

Most of our classrooms and offices tend to have all-in-ones, where we find the supplied power brick is too heavy for this. I generally stick the power brick under the desk in a wire under-desk cable tray - for some reason, Ikea still seem to be the only place that sell reasonably-priced, easy-to-fit, adjustable-by-sawing-bits-off ones:

Sugru is amazing but expensive, an alternative is nano-tape which is amazing stuff but you need to make sure the surfaces actually touch. If there is a bezel in the way or one surface is resessed the tape won't stick properly.

This is the way

Sugru also has a shelf-life and never seems to stay useable if you don't need the whole packet.

 

Thanks for the nano-tape idea. I actually have some bits pulled off old kit that I use, but they were too thick and not the right size to hold my car Bluetooth aux adapter to the head unit's display firmly (head unit looks to be far too much like hard work to replace). Once I realised that you can buy it and what it was called, nano-tape to the rescue!

Make it a requirement of purchasing (your IT tech spec) that monitors have to have a standard kettle lead plug - end of, or IT don't support it.

 

I don't even buy my own monitors with barrel-style connectors for largely the same issue.

Yes, I agree but my point is that we are not getting that option due to them changing the power source.

We have some monitors with wall wart power bricks - the plug is the transformer. So, you can't even be sure if those with barrel plugs use the mid-line transformer style power connectivity.

 

Realistically, this is where you need to work with an account manager at a decent reseller and get them to go and find the specifics for you before purchase. Buying online will only ever be down to luck.

Both great ideas, but what about chewing gum. The kids very thoughtfully always leave plenty of it under the desks for just such occasions ;-)
