600W MicroTCA power modules from Emerson Network Power

MTC600 series MicroTCA power modules are high power density, single-width units; the ac-input MTC600-AC version is 12 HP high and the dc-input MTC600-48 version is 9 HP high. The MTC600-AC has an input range of 90 to 264 Vac, making it suitable for use with single-phase supplies virtually anywhere in the world, while the MTC600-48 has an input range of -39.5 to -72 Vdc, which accommodates both -48 V and -60 V battery plants. The MTC600-48 also supports 1+1 input redundancy – it features dual A’ and ‘B’ inputs with built-in ORing devices, and is equipped with internal fuses on both of the power feeds and both of the return lines.

Both versions of the MTC600 power module provide 16 output channels, each capable of delivering 12 V @ 7.6 A of payload power & 3.3 V @ 150 mA of management power. This is sufficient for a complete MicroTCA system comprising up to 12 AdvancedMCs (AMCs), two MicroTCA Carrier Hubs (MCHs) and two Cooling Units (CUs). The MTC600 module automatically provides power for the MCH and CU system elements at power-up; all other MTC600 output channels are controlled by the carrier manager, which communicates via the power module’s built-in Intelligent Platform Management Interface (IPMI).

All MTC600 series power modules support N+1 output redundancy and hot-swap operation; removing or adding a power module will not cause a fault or out-of-regulation condition. Furthermore, the power modules implement both module-level and channel-level fault isolation, which means that if one module develops a fault, it will not cause the other to shut down – an essential attribute for high-availability systems.

MTC600 series power modules are comprehensively protected against overvoltage, undervoltage and overtemperature conditions, and feature extensive monitoring and reporting facilities for power system status and operational conditions. Each of the 16 payload power outputs, as well as each of the 3.3 Vdc management power outputs, is protected against short-circuits and provides status feedback to the carrier manager; in the event of a fault, the appropriate channel will automatically shut down without affecting any of the other 15 channels.

Emerson Network Power’s MTC600 series MicroTCA power modules provide a completely self-contained solution: their input power conditioning circuitry includes all necessary EMI filtering, transient suppression, inrush current limiting and power holdup. The modules are designed for operation over NEBS-compliant ambient temperature ranges, at full load. They can cold-start from temperatures as low as -20°C and can operate at short-term temperature peaks of +55°C without damage.

The power modules meet EN55022 Class A conducted and radiated emissions standards, and comply with applicable EMC immunity standards, including EN61000-4-2, -3, -4, -5, and -6. The modules carry IEC 60950-1 safety approvals.
