CAUTION!
Do NOT apply 12V power to more than a single input source. For example, do not apply
power to J73 and J27 at the same time.
CAUTION!
The KCU1250 board uses a P-channel MOSFET power switch (FDS6681Z, reference
designator Q1) that is rated for 20A @ 12V. It is critical that the power consumed by the DUT and
peripheral circuitry does not exceed this limit.
Power Switch
The KCU1250 board main power is turned on or off using the SW1 switch (callout 2,
). When the switch is in the on position, power is applied to the board and the
green LED DS18 illuminates (callout 15,
