i just started learning how a center tapped smps works and i did some test but now i am confused about the dual power distribution, i mean if a device input power rating is a centered tapped, say +12_0_-12 VDC, when we measure it with a multimeter the +12 and -12 the voltage is 24VDC but we can't use the 24VDC on a single 12v:0v device it short circuits the smps. When we measure the +12 and the GND the voltage is 12VDC and we can even use the +12v:GND(ignoring the -12VDC) with a single 12VDC device, so my question is, does the center tapped device actually uses the 24VDC or the device splits the 24VDC into 12VDC/12VDC. Thank you.
I want to understand, just say a 500watt RMS Mosfet mono amplifier the maximum input VDC is rated at 56_0_56VDC, when we test with a multimeter the +56v and -56v voltage is 112VDC. so i want to know does the amplifier uses the entire 112VDC or it splits the voltage into two 56_0_56VDC because if the amplifier uses the entire 112VDC then i think the 112VDC is a lot of voltage and could burn the amplifier. Thank you.
