MicroTCA low-voltage DC/DC Power Module providing 300W or 600W

The NAT-PM-DC600LV is a full-size MicroTCA power module for AdvancedTCA™ and µTCA™ applications available in 300W and 600W versions, each with a single- or double-width front panel. It is a hot swappable, fully redundant and high efficiency power module ideally suited for all air-cooled systems. 

This DC/DC power module provides payload and management power for up to 12 advanced mezzanine cards (AMCs), two cooling units and two MicroTCA carrier hub (MCH) modules. The NAT-PM-DC600LV provides power conversion from two 24 Vdc input sources to 16 independent 12 V channels for payload power and 3.3 V for management power. The power module provides backup power for other power modules (shared management power or SMP) in the system.


The NAT-PM-DC600LV power module includes an enhanced MMC (EMMC) supporting an intelligent platform management bus (IPMB) to enable communication with the carrier manager or MCH.

Redundancy and Load Sharing

The NAT-PM-DC600LV supports redundancy as well as load sharing modes in accordance with the MicroTCA specifications. In case of an input power supply failure the onboard EMMC can be provided by SMP power from other PMs, so that the MCH is able to analyze root cause failure.

LED Indicators

Besides the standard indicator LEDs for hot-swap, failure and heartbeat the NAT-PMC-DC600LV has an optical load indicator that continuously displays the level of power utilization of the whole system.

Other Features

The two power inputs offer features such as input protection, input isolation, inrush control, input ORing, EMI filtering, and holdup circuit.
