Gresham Power Electronics has introduced the PS-1138 high-power module designed for use in MicroTCA systems. It supports shelves, cubes, MicroTCA enclosures, and complies with the PICMG MicroTCA Revision 1.0 specification. The power module provides functionality for powering, managing and protecting a MicroTCA system that includes up to 12 advanced microcontrollers, 2 MicroTCA carrier hubs and 2 cooling units.
The power supply provides 600W of output power in the form of 16 channels of 12V at 7.6A and 16 channels of 3.3V at 150mA. It 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, claims the company. The module is also claimed to support redundant IPMI communication with the MCH/carrier-manager, enable and provide power to AMCs, CUs, and additional MCHs and include an enhanced module management controller using two IPMBs - IPMB-A and IPMB-B.
The MicroTCA power supply has a universal input voltage of 90 to 264V AC at 50/60Hz and has 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 -10 to 55ºC at full load with 300 LFM forced air cooling, random vibration tested from 10 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. The power supply is suitable for enterprise and data communications, telecomms edge applications and customer premises equipment, digital imaging, industrial and medical equipment.
