Power - ARM MPS2 Technical Reference Manual

Power

You supply power to the board from the mains supply using the on‑board connector and the connector
cable that Arm supplies with the board.
Arm supplies an external power supply unit which converts mains power to 12V DC which connects to
the 12V connector on the board. The unit accepts mains power in the range 110V AC to 240V AC.
If you supply your own external mains adaptor, it must be a Low‑Power Source. Some such are marked
LPS on their rating label. Otherwise it might be necessary to consult you adaptor supplier to ensure that it
meets this criterion.
Alternatively, you can connect an external 12V DC supply, +/- 10%, directly to the 12V connector.
Any external 12V DC +/- 10% power supply that is used must be a limited power source.
On‑board regulators supply power to the board power domains and to the FPGA power domains.
The PWR LED illuminates when the MCC is powered up and active.
