Nortel NTR651BC 400W DC-DC power and fan unit for the DMS-100 SAM21 shelf.

The Nortel NTR651BC is a DC-DC power and fan unit for the DMS-100 SAM21 subscriber-access shelf. Built around an Artesyn 400W DC-DC converter, it supplies the regulated DC voltages the SAM21 peripheral modules require and provides the forced-air cooling that keeps the densely packed shelf within its thermal limits. The NTR651BC sits in the power position of the SAM21 shelf alongside the alarm and breaker modules, forming part of the powering and cooling framework of the DMS-100 central-office switch rather than being a subscriber or trunk circuit pack. The DMS-100 is a Class 5 digital switch still in carrier service worldwide, so spare NTR651BC power and fan units remain in demand for ongoing maintenance. We supply the NTR651BC refurbished and tested. Submit a price enquiry for availability and lead time.

Worldwide supply. We export new and refurbished telecoms and networking equipment internationally. International buyers welcome, request a delivered quote in your currency. Supply subject to export checks.
