Larry, I favor a linear regulated supply rather than a switching supply. I had a TBolt die while connected to a switching supply in an environment where there were frequent power outages.
The +12 VDC current drops significantly after the OCXO warms up, probably down to about 200 mA or so. Good luck. They are neat little devices.

I am a new member of the mail list. I've been using a HP Z3801A GPS-steered standard but have just acquired a Trimble Thunderbolt GPS Disciplined Clock. I'm seeking a recommendation for a power supply for this Thunderbolt receiver. There is much discussion about noise from some switching supplies and the effect on phase noise of the 10 MHz output. The Thunderbolt manual specifies the following supply and loads: +12 vdc 750 mA + 5 vdc 400 mA -12 vdc 10 mA This combination is somewhat unusual in that the highest current is on the 12 volt output rather than the 5 volt output. I'm asking if list members have a favorite power supply for this unit, why and where I can obtain one. -- Best wishes, Larry McDavid W6FUB Anaheim, CA (20 miles southeast of Los Angeles, near Disneyland) _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. ----- No virus found in this message.
