24 VDC 6A 145W Regulated Switching Power Supply
What would be the idle power consumption of this power supply when connected to the 6x100W TDA7498 Class-D Amplifier Board?Thanks a lot!
The rated idle (0dB) current consumption of the TDA7498 6x100w board is 40mA or around 1 watt when supplied 24VDC.This power supply is rated to consume <2mA at idle plus 12% of 114% of the load's consumption at 24VDC (because it is rated 88% efficient) - or about 0.15 watts.So including wire losses/etc, expect this unit to consume about 2 watts when powered on and connected to that amplifier board while not receiving any signal.

i would like to get one of these sure boards,but i dont quite know how to hook it up. Do these come with a manual?
Yes, there's a manual but it's fairly general with regards to power supplies because it is expected that there is a great deal of common knowledge about electronics. /me makes note of your age... Yeah, I certainly don't discourage you from learning more about this. Take a look at the 3rd enlarged picture. Consider the power cord below. (IIRC, plz check this!) the black wire is always the "live" wire so connect that to "L". The white wire is the "neutral" so connect it to "N", the green wire is ground so connect it to the position with the ground symbol. There is some kind of concern about the power available from a single trace so therefore the unit splits its output into two channels. It should be safe to tie both "common" to the load's "-" input, and the both "+V"'s outputs to the load's "+" input. I'm not sure if this unit is isolated, if it is, then it might be necessary to put a switch between the "com" grouping and the ground, depending on the situation. Also, use a volt meter to adjust the voltage between "com" and "+V" using the adjustment pot.

Can it switch to also output 12V DC?
The output of this power supply is fixed at 24 VDC.
