DC Power Supply for Cisco 3900 Series

The KHACHIMO PWR-3900-DC 341-0240-01 is a new DC power supply built for Cisco 3945/K9 and 3925 routers. It delivers the rated 3900 watt capacity required by those chassis. Each unit is tested working before shipment to confirm reliable operation in supported hardware.

Replacement for failed or missing router PSUs

Install this supply when the original DC module has failed or when a redundant slot is empty. The upgrade is worth it if your router runs mission-critical services and needs hot-swap redundancy. Buyers who need an AC-input version or a supply for a different router series cannot use this unit.
