I posted on here a while ago regarding which size (value) of fuse should go into the plugs of which appliances.
I live in the UK and sometimes buy rackmountable audio recording equipment from mainland Europe. Because they assume that most customers come from mainland Europe, they always include the standard Euro-type plug for connecting to the IEC power connector at the rear of the equipment which means I have to find my own IEC (C13) power cable to use in the UK.
Okay...I'm aware that there's a formula for calculating an appliance's current draw from an electrical outlet providing I have that particular appliance's details.
Power(W) = Current(A) x Voltage(V).
Am I correct in assuming that if I use this formula modified to Power(W)/Voltage(V), then this will equal an appliance's Current draw in Amps(A)? If so, do I then go with a fuse in my plug which is slightly higher than this? Basically, the next highest commercially available fuse I can buy? Am I correct so far?
Anyway...I took receipt of a preamplifier unit the other day which has an external Power Supply Unit (PSU) with the following details on the underside of the PSU.
Input: 100-240v~1.6A Max, 50-60Hz
Output: +15v 3.33A
Output Power: 50W Max
The preamplifier's manual states.
Voltage range: 9 to 18 Volts DC
@ 9VDC Current is 1000 mA typical: Power = 9W
@ 12VDC Current is 800 mA typical: Power = 9.6 watts
@ 15VDC Current is 610 mA typical: Power = 9.15 watts
@ 18VDC Current is 520 mA typical: Power = 9.36 watts
I'm a bit confused as to which size (value) of fuse to go with in my plug.
Is the current draw 1.6A or 610mA? Which size (value) of fuse would I use in my plug?
Obviously, I will buy the correct rating of cable and plug especially for the unit instead of switching fuses in a 13A cable I already have as I'm aware that was suggested the last time I posted here.
Any advice would be greatly appreciated.
