More Zephyr technical info

Hi all,

I bought a Zephyr recently. Because I imported it from the US to the UK, I bought it without the US-spec power supply. So I needed to find out how to connect my own power supply. For the benefit of anyone else who does this, here's what I learnt:

Power input socket:
  • the input requires 15V (rms) AC 50/60Hz (must not exceed 16V rms)
  • alternatively, 18V DC may be used (must not exceed 22V DC)
  • the supply requires up to 2.5A to meet the full capability of the Zephyr.
  • the connector is 5.5mm dia. (outer), 2.0mm dia. (inner)
  • for a DC supply, the centre pin is positive, the outer conductor is negative.

QUOTE (darobi @ 22 Dec 2006, 18:26) <{POST_SNAPBACK}>A unit will only draw what current it needs so excess capacity isn't an issue in normal running conditions.

HOWEVER if a fault occured and the fail safe didn't blow (i.e. the fuse or cutout trip) then the unit could draw far more power then is required doing some damage or burning out the unit completley.

My digitrax manual recommended that any power supply for the Zephyr be limited by a fuse or circuit breaker to 3 amps.
Apologies for resurrecting an old post :^)
