An ARC’s power requirements vary depending on the voltage supplied to it. For example, an ARC-2e at 24V DC uses approximately 55 mA, while at 7V DC it uses approximately 170 mA maximum. As the voltage varies from 24 to 7 VDC, the current requirement increases accordingly. ARCs can be daisy-chained and fed power over this daisy-chain from an ARC-PSe (see below) or other device. However, as the length of the cable increases, so does the resistive line loss, which lowers the voltage available at each subsequent ARC. The actual power drain on each output from the powering device can vary substantially depending on the number of ARCs and the distance each of them is separated by. In order to assist with system design, Symetrix has available a Microsoft Excel spreadsheet that can help a system designer determine power requirements based upon cable length, number of ARCs and the power supply to be used.

- Distributes power and data to multiple ARC wall panels via eight RJ-45 connectors over long distances.
- Connects directly to Symetrix DSPs using standard CAT5/6 cables.
- Supports flexible ‘star’ configuration, ‘daisy-chain’, or a hybrid of the two.
- Versatile half-rack design. Mounts in an optional 1U rack tray or surface mount with optional bracket.
