Determining Power Requirements

Both the SNAP-PS5 and the SNAP-PS5-24DC power supplies provide 5 VDC power for loads up to 4 amps. The
SNAP-PS5U provides 5 VDC for loads up to 5 amps. In most cases this power is sufficient for a SNAP processor,
a rack, and the associated I/O modules. However, some combinations of modules, especially special-purpose
modules, may require additional power. You can use the following table to help determine power needs for
your I/O units.

IMPORTANT:

For a SNAP-PS5 or a SNAP-PS5-24DC power supply, the total power required must not exceed 4

amps. For a SNAP-PS5U, the total power required must not exceed 5 amps.
