A 1,000W power supply for MicroTCA applications

20 April 2014

Gresham Power Electronics has added the 1,000W PS-1142 high-power module for MicroTCA applications to its power supply portfolio.

The PS-1142 supports shelves, cube, and other mechanical implementations and complies with the PICMG MicroTCA.4 Revision 1.0 specification. It provides functionality for powering, managing, and protecting a MicroTCA system that includes up to 12 AdvancedMCs, 2 MicroTCA Carrier Hubs and 2 Cooling Units.

Provision is made to read the current of each output module and an IPMI (Intelligent Platform Management Interface) is provided to allow system administrators to update the power supply firmware if required.

Key Features include: 1,000W output power, 16 channels of 12V @ 7.6A, 16 channels of 3.3V @ 200mA, hot swappable N+1 output redundancy, protection against overload, short-circuit, over-voltage, and over-temperature conditions and Class B conducted emission standards compliance.

The unit also monitors and reports power system status and conditions of operation, manages and isolates faults that affect the power system, provides the power necessary for MCH and CU system elements on system bring-up, supports redundant IPMI (IPMB-0) communication with the MCH/Carrier-Manager, enables and provides power to AMCs, CUs, and additional MCHs under the command of the carrier manager and includes an Enhanced Module Management Controller using two IPMBs (IPMB-A and IPMB-B).
