I actually built a 48 volt supply inside of my Z3801A. There is just enough room between the front panel and the pc board to install a transformer, in my case two, and a bridge. A large electrolytic is mounted horizontally to the back panel. The 48 volt connector location was modified to accept a regular 3 prong filtered AC connector. Has been working great for about 7 years now. I also replaced the top cover with a copper screen mesh to keep it cooler. Not sure if it was necessary, it just seemed the original top plate got very warm. Regards - Mike

I just noticed that Jameco unit is not for 12VDC input. The "A" model here is the correct one: http://www.trcelectronics.com/Meanwell/sd-50a-24.shtml In any case, I still can't find something similar with a 48VDC output. ---------- Forwarded message ---------- From: Joseph Gray <[email protected]> Date: Fri, Sep 25, 2009 at 7:59 PM Subject: DC-DC converter To: [email protected] Does anyone know where I can get an inexpensive 12VDC to 48VDC converter to power one of my Z3801A's? I can find 12VDC to 24VDC units, like this one at Jameco: http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&sto reId=10001&catalogId=10001&productId=212514 Thanks. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
