PS Replacement Question

[rkelly1]

Chris/Team - I received a power supply replacement (
PS-400W-AC
) for a Wisp WS-24 AC switch, one of the early ones. Looks like an exact replacement except for the power in pins.

The new board has two pins for the power, the old has 4 pins. On the old, the two white and the two red merged together into one before going to the AC plug so effectively there is just two pins on the old board and this can match up to the new board.

The question is, the old board and new board pins swap the N and the L wires on the power input if I use the same connector.

On the old board, the N was attached to red and the L was attached to white. If I use the same connector, this is swapped on the new board. Does it matter?

Thanks,
Rob

That was caused by one batch of power supplies had the wrong connector (4 PIN) by the China factory but if your careful they should connect fine, center the smaller connector on the larger connector, 1 extra pin on each side.

This power supply is a stock unit they make for many customers each with a custom connector, we got a small batch with another customers connector.

If your unsure simply post a picture here so I can advice.
