I am just wondering at what voltage would be considered a severe under voltage in NZ for electronics i.e. computers?

Today I have seen as low 216V and I wonder if it is something to do with the strong winds...

I have a CyberPower PFC Sinewave Series 1500VA UPS and the maximum under voltage setting available for it to switch to battery in an under volt condition is 180V. Is 180V a little to low to still be running off mains power?

Most computers and associated electronics have switch mode power supplies that can work quite happily down to 110v. Printers can be more fussy

Sounds like there's nothing to worry about with under voltage on the PC then...

Laser printers shouldnt be plugged into the UPS though :-)

In NZ the voltage should be 230V +/- 6%

It doesnt meet legal supply if it is less than 216.2V or more than 243.8V

I am regularly lodging overvoltage faults with our lines company for excessive voltage in rural areas. I once found a woolshed with a supply of 260V
