Legacy / end-of-life

Eaton APR48 rectifier modules

The APR48 family sits behind a large installed base of Eaton and former Access Power DC plants, particularly in operator networks built through the 2000s and 2010s. Requests here are almost always maintenance-driven: a module has failed and the site cannot wait for a plant refresh.

Availability & lifecycle

Largely legacy. Several APR48 variants are no longer current orderable products and are sourced from remaining inventory, so we confirm availability per request rather than publishing a figure.

Models we are asked for

Part number	Model	Indicative specification

Specifications are indicative and published by the manufacturer. Availability, exact revision and lead time are confirmed in the written quotation.

What to send us

The APR48 variant suffix, a photo of the label, and the system controller. On this family the suffix is the difference between a part we can source and one we cannot.

Compatibility notes

Where an APR48 variant is genuinely unavailable, the practical route is often a compatible module plus a controller settings change. That is an engineering call and we will walk through it rather than guess.

Common questions about this family

Is the Eaton APR48 still available?

Several APR48 variants are no longer current orderable products and come from remaining inventory, so availability varies by variant. The suffix is what decides it: an APR48-3G and an APR48-ES are different parts, and one may be sourceable when the other is not.

What do I do if my APR48 variant cannot be found?

The practical route is usually a compatible module plus a change to the controller settings, rather than hunting indefinitely for an exact match. That is an engineering decision, not a catalogue lookup — send the plant and controller detail and we will walk through the options.
