Gresham - High Performance 600W MicroTCA Power Supply
Gresham Power Electronics, the Salisbury based MIL and Commercial power conversion specialist, introduces the PS-1138 high-power module designed for use in MicroTCA systems. It supports shelves, cubes, MicroTCA enclosures, and other implementations and complies with the PICMG MicroTCA Revision 1.0 specification.
The PS-1138 provides functionality for powering, managing and protecting a MicroTCA system that includes up to 12 Advanced Micro-Controllers, 2 MicroTCA carrier hubs and 2 cooling units.



MicroTCA offers the telecom market a standardised, highly configurable, hardware platform for a broad range of applications, able to be produced in high volumes at low cost. MicroTCA provides a system architecture allowing AdvancedMC mezzanine cards to be plugged directly into a MicroTCA backplane without a carrier card and its associated costs. The MicroTCA architecture offers high availability systems from none to fully redundant as hot-swappable cubes.



The Gresham Power Electronics PS-1138 provides 600W of output power in the form of 16 channels of 12V @ 7.6A and 16 channels of 3.3V @ 150mA. The PS-1138 is hot swappable, can be configured for N+1 redundant operation, provides monitoring and reporting of power system status and can manage and isolate faults affecting the power system. The PS-1138 also supports redundant IPMI (IPMB-0) communication with the MCH/carrier-manager, enables and provides power to AMCs, CUs, and additional MCHs and includes an Enhanced Module Management Controller using two IPMBs (IPMB-A and IPMB-B).



The new Gresham PS-1138 MicroTCA power supply has a universal input voltage of 90 – 264 VAC @ 50/60Hz, offers > 90% efficiency and a power factor of 0.99 typical. It is protected against overload, short circuit, over voltage and over temperature and meets Class B conducted emission standards. Environmental specifications include an operating temperature range of -10ºC to 55ºC at full load with 300 LFM forced air cooling, random vibration tested from 10Hz to 500Hz, 3 axis, 1.9 GRMS maximum and shock tested at peak acceleration of 1GPK maximum. International safety standards pending include UL, cUL 60950-1, CSA 60950-1 and VDE 60950-1
