did you notice Basslines' post about the Zerozone 100VA PSU stock fuse perhaps being intended for a 240VAC applicationYes, I read it.
If the unit was made to be fed from 230Vac the max rated primary amps would be,
100VA / 230Vac = 0.43 amps.Fuse size, using the 200% for the 120Vac mains calculation,
200% X 0.43 = 0.86 amp. Just a guess the manufacture would install a 1 amp fuse or the next lower size near 0.86 amps.EDIT:
Though I would not use 200%. At most 150%. 150% X 0.43 = 0.65 amps. Fuse closest to 0.65 amps.When you get a chance measure the mains voltage at the wall outlet the power supply plugs into.
Also the secondary AC voltage of the transformer loaded with 12Vdc load connected.
And the DC out voltage with the load connected.Is the power supply left on 24/7?
Is the connected load left on 24/7?
