1000W MicroTCA AC/DC Power Module

The NAT-PM-AC1000 is a 1000W full-size, double-width MicroTCA (μTCA™) AC/DC power module that provides payload and management power for up to 12 advanced mezzanine cards (AMCs), two cooling units and two MicroTCA carrier hub (MCH) modules. It is a hot swappable, fully redundant and high efficiency power module ideally suited for all air-cooled systems.

The NAT-PM-AC1000 provides power conversion from one wide-range 110-240 VAC input source to 16 independent 12 V channels for payload power and 3.3 V for management power. The power module provides backup power for up to three other power modules (shared management power or SMP) in the system.

The NAT-PM-AC1000 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-AC10000 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-AC1000 has an optical load indicator that continuously displays the level of power utilization of the whole system. It also contains current sensors for each of the 16 power channels, allowing you to determine the actual current draw for each channel.

Other Features
The two power inputs offer features such as input protection, power factor correction (PFC), EMI filtering, and holdup circuit.
