PSU-1848 Power Supply Kit
A power transformer is required.
DO NOT CONNECT THE 110/220 AC LINES DIRECTLY TO THE PCB.
For this discussion, I'm assuming you're using the 1U or 2U PWR-TRAFO kit that I'm selling.
STOP! READ THE DIRECTIONS BELOW:
First, determine which power transformer kit you have. I supply (2) kinds of Power Transformer Kits. Look at the photos below.
If you are using a different brand/model of transformer, please consult the manufacturer for their documentation.

110 VOLT OPERATION
For 110V operation, we need to connect the primaries in parallel.
Connect the BLUE and VIOLET wires together.
Connect the GRAY and BROWN wires together.
Connect both across the 110V line.
USING THE 2U PWR-TRAFO KIT TRANSFORMER
(photo shown above)
110 VOLT OPERATION
For 110V operation, we need to connect the 2 primaries in
parallel.
Connect the (2) RED wires together and connect the (2) BLACK
wires together.
110V is applied across the RED and BLACK wire.
