5V DC 2.5AMP POWER SUPPLY

The Adder PSU-IEC-5VDC-2.5A is an optional or additional 5 V DC, 2.5 A power supply for most Adder products. It provides a separate power source for compatible Adder equipment when an extra supply is needed.

The unit connects to a relevant local IEC lead, which the product page says is supplied. Its stated purpose and electrical rating identify the supply, but no specific compatible device models are listed.
