Thank you for viewing. High-performance power supply unit with AC 100V input and DC 12V output. This is a regulated power supply. - Brand: KYOSHO - Model: Power Zone PS-25A - Input Voltage: AC 100V 50/60Hz - Output Voltage: DC 12V 20A Although the photos show some noticeable scratches, I think it's in relatively good condition for its age. I hope those who understand that this is an aged item will consider purchasing it.
