We’re light on surfboards and ironing boards right now (aren’t they the same thing, anyway?), but we do have (2) nice circuitry boards, both 4” x 5”. You pick: the (8)-channel relay module board (actually a switch board) with (9) fuses protecting a terminal block connection, (1) input +/-, (8) outputs, all terminal block screw contacts, an on/off slide switch and green indicator; or the filtering circuit board originally used with closed circuit cameras, with a 120VAC terminal block input, 12VDC outputs via (2) separate terminal blocks, LED indicators for both live AC and live DC, and unknown amperage, but it’s part # DPS0401-2, so you might be able to find more info, resourceful as you are.
