39-inch 48V Battery Extension Cable

This 39-inch black cable connects an APC Smart-UPS X-Series 48V external battery pack to the UPS unit. It is built for installers who need a short, secure link between the battery cabinet and the power-protection system in a rack environment.

Locking IEC Cord Retention

The cord uses a patented locking IEC connector that resists accidental disconnection when paired with compatible AP8000 series rack power distribution units. This retention method frees the installer from relying on friction-fit plugs that can loosen under vibration or cable-management tension.

Run Rack Integration

The 39-inch length suits side-by-side or adjacent rack mounting where the battery pack sits close to the UPS or PDU. It does not reach across full-height cabinet rows or between separate enclosures, so longer runs require a different cable.

Questions about this item

How far can the 39 inch cable reach between the UPS and the external battery pack?

The SMX039-2 measures 39 inches end to end, giving that exact separation between your Smart-UPS X unit and the 48V battery pack.

Will the cord or connectors get warm during continuous operation?

As a passive power cable it carries only the DC current between the UPS and the 48V battery pack, so it does not generate noticeable heat of its own.

Which UPS models accept this 48V battery extension cord?

It is built for APC Smart-UPS X-Series units that use a 48V external battery pack.
