From: Richard Erlacher <edick(a)idcomm.com> turns float ///snippage//// I have three working plus a TK50 in an external box (same box), if that isn't enough I must have 6 or so of the PSUs that I use for "projects". The PSU wants a 10W load minimum on both the +5 and +12. It's rated 160W OUTPUT. It easily runs a P166 with options. The +12 is heafty enough to run a MAXTOR2190 with reserve figure it for not less than 4A. The remainder is on the +5, If memory serves it's good for 12A++. The minus voltages are for RS232 type use figure them for .5A. The "floating line" is powerfail and is open collector. I rarely use it. Have fun
