12 Volt DC Power Supply - This is a simple low-cost 50W off-line
switching power supply, which can be used for home projects or to learn
operation of flyback converters. It can work over a universal AC line
input range 90-264 VAC and provides a 12VDC output at more then 4A load.
Line and load regulation is better then 0.5%. |
|
12 Volt Power Supply - Please operate caution when building this
power supply. It is run on standard 117 ac current and under right
circumstances 117 ac can kill you. Use a plastic enclosure if possible
to decrease chances of short-circuiting. Don't use power supply if
it's wet, and never run it without specified fuse. |
