The NAT-PM-AC600 is a high-density and high-efficiency power module (PM) for MicroTCA™ applications. Supplying 600W it is the market’s most efficient PM in its single-width full-size form-factor to run today’s complex communication systems made of latest processor generations and an increased number of Advanced Mezzanine Cards (AMC™). The NAT-PM-AC600 provides electrical support for the expected workload of 12 AMCs, 2 Cooling Units (CUs) and 2 MicroTCA™ Carrier Hubs (MCH).


The NAT-PM-AC60 includes a robust Enhanced Module Management Controller (EMMC) that interfaces the power control functionality via the Intelligent Platform Management Bus (IPMB) to the MCH.

Redundancy and Load Sharing

The  NAT-PM-AC600 supports redundancy as well as load sharing modes in accordance with the MicroTCA™ specifications. In case of an input power supply failure the power for the onboard EMMC can be provided by SMP power from other PMs, so that the MCH is able to analyse root cause failure.

LED indicators

Besides the standard indicator LEDs for hot-swap, failure and heart-beat, at its front panel the NAT-PM-AC600 provides a unique light bar indicator, showing the PM’s total power load on a 0-100% scale in steps of 10% in real-time.


The NAT-PM-AC600 is a hot-swappable, fully redundant and highly efficient AC/DC power module. The module’s single-width design offers perfect thermal performance and therefore is ideally suited for all air-cooled MicroTCA™ solutions. The NAT-PM-AC600 is fully compatible with any standard compliant FRU being insertable into a MicroTCA™ chassis. The NAT-PM-AC600 could easily serve applications like
  • commercial and military (tele-) communications
  • automated test equipment
  • medical
  • video
  • security
  • industrial machine control
  • clustered computing architectures
For N.A.T., the NAT-PM-AC600 is a further and consequent milestone in developing a broad and harmonized MicroTCA™ eco system. The PM serves as a central power converting and conditioning control block for entire sub-racks. N.A.T. offers sophisticated and standard compliant MicroTCA™ systems, either as turn-key solutions or building blocks. This offer is complemented by a large variety of own MCHs, telecom line interface and network processor cards, PrAMCs, I/O cards, chassis, CUs and PMs.

Family of MicroTCA power modules

The NAT-PM-AC600 is a member of the NAT-PM family of MicroTCA power modules which consists of:

N.A.T. MicroTCA Portfolio
The NAT-PM-600 complements the extensive N.A.T. portfolio of MicroTCA solutions, which includes chassis, management modules, power modules, processors AMCs, IO modules and specialist accessories.
