[time-nuts] Thunderbolt Supply commercial option

[Robert Atkinson]

One commercial linear power supply that works well for the T-bolt is Power one's HTAA-16W.
This is a 16W triple output 5V 2A +12V (or 15) 0.4A -12V 0.4A unit. While 0.4 is under the warm up rating for the T-bolt it's OK for running. The fact that we are well under running it on +5V and -12V means the +12 is OK at 0.6 to 0.7A for short periods. The 10% derating for 50Hz v 60Hz tells me the transformer is the limiting component. Spreading the load across ratings is OK. They are available new and surplus. New is about $100 but surplus they run 99p to £20.
