Lenovo 00FJ635 -48V DC 2500W server power supply

-48 V DC 2500 W server power module

This Lenovo 00FJ635 power module delivers 2.50 kW of output power for enterprise server platforms. It accepts a -48 V DC input voltage, making it suitable for telecom and data-centre environments that run on DC power infrastructure. The unit is supplied in new condition and is designed to fit compatible Lenovo server chassis. It targets system integrators and operators who need high-density DC power for rack-mounted equipment.

Hot-plug redundant power for compatible Lenovo

The module slides into a supported server bay and works alongside identical units to provide N+N redundancy without shutting down the system. Its -48 V DC input connects directly to facility DC distribution buses, eliminating the need for local AC-to-DC conversion at the rack. This architecture frees up space that would otherwise be occupied by bulky AC power supplies and associated cabling. Installation requires a chassis with matching mechanical keying and backplane connectors.

Sustained 2.50 kW delivery under continuous load

The power module is rated to supply its full 2.50 kW output continuously while operating within the thermal limits of the host chassis. Redundant configurations share the load evenly, so each unit runs well below its maximum during normal operation, reducing thermal stress over long deployments. Built-in protection circuits guard against over-voltage, over-current and over-temperature events without interrupting service. Performance scales linearly with the number of active modules installed.
