Running load might not be quite as bad as you'd expect, switching them all on at exactly the same time would probably cause a nice fat pulse but perhaps that's a bit extreme:-), allowing an adequate margin though is always a good idea. If you could tap into the supply and get an idea of running current that would be a good start, after that it's likely to come down to an appropriate autotransformer, fixed or variable, one of the older style saturable reactance type constant voltage transformers, or perhaps an "online" UPS, sinusoidal to be preferred, that will handle the input voltage and regulate the output. The latter would probably be the best, or easiest anyway, option these day, and assuming it meets your voltage and current needs then the off mains hold up time, unless you do need that too, probably wouldn't be too much of an issue so that could help keep the cost down.

I reckon, the line voltage here is 250v and the equipment is set for 240V, that extra 10V on the mains is why I am having so much equipment failure. Also the Heat sink on the 5370B got so hot I mounted a 5" fan across it to keep it at a respectable temperature. How can I drop the Mains to 240V, I have a boat load of gear that needs to be powered concurrently. (8566A, 8568B, 3585A, 5335A, 5370B, 8901A, etc, powered on together) we are starting to talk some serious current 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.
