FUSE Question...Very Confused Please Help !

@rocky1313

Use a 250V rated fuse per the fuse holder as stated. 250V/5A

#2. AC 110: S5A... 110 is the AC Line voltage setting for the Amp when the wall outlet mains voltage is 110V - 120V. (S5A 250V fuse.)

Are you sure the fuse is a S5A? Using Google I could not find a S5A 250v fuse.

5A = 5 Amps.

S = ? Slow blow?

Sounds to me like it wants you to use a different sized fuze when you switch to 110 v. This makes sense since for the same power, current doubles.

Voltage is pretty much irrelevant on a fuse so you can still use a 250v fuse in a 110 system and indeed, that seems to be what the first sentence requires.

So my thought would be to use a 250V rated fuse of 5 amp, slow blow.

Which is what is in it.

Did you blow a fuse?

From page 6 of owner manual:

V

S

– Mains Voltage Switch (12)

VOLTAGE SELECTOR

The Penta 5.1 amplifier can be used in all

countries and is good both for 110/115 and

220/230 V. Before the first operation, please

make sure that Mains Voltage Switch is set to

the value accepted in your country.

I have it set to #2 setting ....AC 110 : S5A .......... Correct for US.

I would use the 250 volt / 5 amp fuse as the current doubles when dropping to 110. You can buy Bussman replacements on Amazon (250v/5a)- $6 bucks for a five pack. 

what they said.
