I just checked the HP manual, most of the linear equipment is specified: 240V +5/-10% So, I am a little over at 258V here ): I am going to unplug everything until I can get this sorted out. Can't afford to lose anything more, in both time and spares obtainability.

I see that wikipedia says AS60038 calls out 230V +10% -6% so that's 253 to 216 One thing to be wary of is that the utility supplies voltages at, say, 120V or 240V (in the US), but utilization equipment (motors, for instance) is labeled as 115V or 230V. This accounts for the 2% voltage drop in the branch circuit, among other things. _______________________________________________ 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.
