Mine requires the 5 volt supply at 340 ma. Are there nay manufacturer's instructions about mounting, ventilating, or heat sinking these units?
My current thinking is to mount it on standoffs on the back of the chassis that houses my Thunderbolt. Perhaps I should place it where it can warm up Princess. (Notice the magnet on top of the oscillator.) On 12/20/2011 07:13 AM, Roy Phillips wrote:

I just hapened on this power supply in an ad. You might find a fixed voltage one somewhere cheaper, but the price seemed ok, so here it is for consideration...I trust that you are aware that some models of the FE-5680A only require the 15 volt/1.7Amp. supply. In fact connecting a 5 volt supply to the units that are programmable can cause damage !http://www.mpja.com/email/12-13-11.asp?r=284759&s=2 Still need the 5 V somehow, so not a complete solution for the 5680A.

My Tek CPS250 1.2 amp output (A+B parallel) only gets 7.5 volts. Now to scrounge something a bit bigger. --------------------- The 15 volts to pin 1 starts off needing to supply around 1.7 Amps, eventually falling to somewhere between 700 and 800 mA. Pin 4 always draws around 85 to 90 mA from its 5 volt supply. regards Nigel GM8PZRNigelRoy_______________________________________________ time-nuts mailing list -- [email protected]To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nutsand follow the instructions there._______________________________________________ time-nuts mailing list -- [email protected]To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nutsand follow the instructions there.
