48V DC rectifier modules, controllers and telecom batteries

Nine product families, covering the manufacturers behind most of the installed 48V DC base in telecom. Each page states plainly whether the family is still a current product or genuinely end-of-life — because that changes what you should do about it, and because guessing wrong costs a plant.

Read the lifecycle label first

Not everything old is discontinued, and not everything current is easy to get. A family marked active is still manufactured, so the question is price and lead time. Legacy means it comes from remaining stock and availability genuinely varies. Mixed means the platform lives on but specific revisions do not — which is where most compatibility mistakes happen.

If you don't know which one you have

Photograph the label on the front or side of the module, and a second photo of the whole shelf including the controller. Between the printed designation, the shelf format and the controller generation we can normally identify the part even when the model name has been superseded. The shelf photo is the one people forget, and it is often the decisive one.
