Emerson Network Power has launched a series of compact self-contained power solutions for MicroTCA systems. Fully compliant with the PICMG MicroTCA.0 Revision 1.0 specification, the MTC600 series power modules are available in AC-input and DC-input versions, and can support shelves, cubes and other system implementations. Rated at 600W output power, the modules implement all the incoming power conversion, power management and power protection functionality necessary for supplying a fully populated MicroTCA system, according to Emerson.

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 90-264Vac, making it suitable for use with single-phase supplies, while the MTC600-48 has an input range of -39.5 to -72Vdc, which accommodates both -48V and -60V battery plants. The MTC600-48 also supports 1+1 input redundancyit 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 12V at 7.6A of payload power and 3.3V at 150mA 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.

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.

Sample quantities of MTC600 series MicroTCA power modules are available now. Standard lead-time is stock to 8 weeks. Pricing starts at $865 for the MTC600-AC and $825 for the MTC600-48, in 100-piece quantities.
