Ramesh,
Thank you - this'll prove to be invaluable information as I convert a HP
T5630w thin client into use as an PMR connected PABX. I was wondering if
you could comment on their average operational power draw - the official
specs say 50Watts/ 4.16Amps, but a number of people have said in practice
they can be run from a 1.5Amp supply.
Power draw is of utmost importance to me - but having the ruddy thing work
too, is important...! I do have a 23Amp Manson power supply, so I have no
issues with actual power in the home environment, but out on deployment,
I'll be limited to increments of 20Ahr LiFePO4 batteries. Or my 50Ahr deep
cycle SLAs... true monsters...
Once again, thanks for the information Ramesh - it now gives me confidence
to convert these clients to other uses.
Shane.
