Which, being telco material, is likely built to work exactly the way I described: An unclean, unregulated DC bus, and an internal DC/DC converter to clean it up and isolate it. I thought we were talking 'naked' OCXOs. One interesting setup I've seen, and which I'm contemplating next time I renovate my DC supply is this: * 30V power supply powers DC bus through diode. * Battery, also diode to DC bus * Bulk charger for filling up battery after discharge, turns once current decreases to setpoint. * Per battery DC/DC converters from the DC bus does float-charge. The two main points to this is that you can use a heavy duty bulkcharger, without paying for its losses in float-mode, and that each battery (if you have more than one) gets optimal float-charge regulation. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ 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.
