Product Review
The ARISTA PWR-3K-AC-F power supply offers a high-capacity 3kW Titanium AC power solution for the 7300 series, ensuring reliable operation across a range of supported chassis (DCS-7304, DCS-7308, DCS-7316). However, its operation is limited to a specific voltage range (200 - 240 VAC) and requires branch circuit protection of 20A, which may restrict its use in regions with lower standard voltage supplies or infrastructure. Furthermore, it adheres to rigorous safety and EMC emissions standards, but its operational temperature range is confined to 0°C to 40°C, potentially limiting its deployment in environments with extreme temperatures.
