NATIVE-C3-PTM

The NATIVE-C3-PTM is a 3U, 19”-wide MTCA chassis for up to 12 AMCs, which provides superior cooling performance. With up to 12 AMC slots, it offers flexible operation of payload boards. Moreover, the chassis supports up to 4 Power Modules and 2 MCHs, so it grants various levels of redundancy.

Payload Boards

The NATIVE-C3-PTM is a MTCA.0 chassis for up to 12 single-width mid-size AMC modules. Due to its exceptional cooling capacity, the chassis is ideally suited for high-density AMC designs.

Redundant and flexible Infrastructure

The NATIVE-C3-PTM provides up to 2 single-width full-size MCH slots. Moreover, the chassis supports up to 4 single-width full-size Power Modules (2x from the front, 2x from the rear). So numerous redundancy options are feasible.

Superior Cooling Performance

The NATIVE-C3-PTM chassis features 2 Cooling Units (CU), fully managed and hot-swappable. Air flows from front to the rear.

Each Cooling Unit tray owns three counter-rotating fans and one cooling management module (EMMC), which connects directly to the backplane. Thus, the NATIVE-C3-PTM offers a superior air-pressure capability. This means, that the throughput does not reduce much due to dense AMC design.

Total air flow of all fans sums up to 420 CFM (720 m³/h).
