Description
The Cisco PWR-RGD-AC-DC-400 is a rugged, high-performance power supply designed for use with Cisco industrial Ethernet switches and routers. Engineered for harsh environments, it supports both AC and DC input voltages, offering flexible deployment options in mission-critical applications. Its robust metal chassis ensures durability in extended temperature ranges and challenging conditions, making it ideal for industrial automation, transportation, and utility networks. This unit delivers up to 400 watts of power, providing reliable energy to demanding network infrastructures.
Key features include support for 88–264 VAC or 88–300 VDC input, with a 54 VDC output optimized for Cisco’s ruggedized network devices. The power supply is designed for DIN rail or wall mounting, with built-in protection mechanisms such as over-voltage, over-current, and over-temperature safeguards. Passive cooling ensures quiet operation without the need for internal fans, reducing points of failure in field deployments. When purchasing used, buyers should verify the condition of connectors, mounting brackets, and ensure all original components such as terminal blocks are included for full functionality.
