-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.

Questions about this item

How long can the 2500 W output be sustained before thermal limits reduce power?

The module is rated for 2.50 kW continuous output; thermal protection will throttle only if chassis airflow falls below the system design requirement.

What is the typical fan noise and heat output when the unit runs at full load all day?

Dual counter-rotating fans move enough air to keep exhaust temperature within Lenovo spec; acoustic level is comparable to other 2.50 kW -48 V DC modules in the same form factor.

Which Lenovo chassis and backplane must already be installed for the 00FJ635 to connect and share load?

The module slides into any Lenovo server chassis that accepts a -48 V DC 2.50 kW power module and uses the standard blind-mate connector on the rear backplane.
