Nortel NTK505DAE5 (telecommunications transmission and networking portfolio) Telecom System Card / Module

The Nortel NTK505DAE5 is a 60A breakerless DC power input card for the OME 6500 shelf, feeding regulated -48V DC into the shelf’s power distribution without an onboard circuit breaker, relying instead on upstream protection in the rack’s power distribution unit. It sits in the same NTK505-prefix family as this catalogue’s confirmed 40A breakerless power interface and message interface controller cards for the same shelf, with current rating (here 60A) the key distinguishing spec between variants. Confirm the shelf’s power budget and whether your site uses breakered or breakerless distribution before ordering, since the two are not interchangeable. The OME 6500 was Nortel’s DWDM optical transport platform and power cards like this are ordered as exact matches to the existing shelf build. Tech-Star (UK-based, shipped worldwide) sources and supplies Nortel hardware to order. Contact our sales team for availability, condition and a price.
