Power interface module enables data communications

Suitable for any industrial, telecommunications and data-communications application employing distributed power architecture, the quarter-brick PIM4328P is optimised to simplify design in blade servers based on Advanced TCA (PICMG 3.0) systems.

Ericsson's low-EMI design rules and best practices ensure that minimal external filtering is needed to meet the CISPR Class B EMC standards required for information and communications technology (ICT) applications.

Ripple and noise are minimised, circuit design is simplified and both parts count and system costs are reduced, without compromising performance.

Based on Ericsson's energy-optimised platform, the PIM4328P operates over an input range of 36 to 75V and the main unit is able to sustain a permanent output current of 10A without forced airflow up to 70C and up to 90dC with only 2m/s (400LFM).

Output power is 390W at minimum 39V input and up to 540W when the input is minimum 54V.

This allows headroom when there is a need to upgrade boards with new processors or additional memory in systems operating in battery or non-battery back-up applications.

With 99 per cent typical efficiency at 300W output, the PIM4328P maintains the high standards of dynamic and load step performance required in ATCA equipment while limiting power losses across the filtering unit to a very low level.

The 2,250V DC isolated, dual power management, 12W DC/DC output voltages are 3.3V/3.6A and 5V/0.15A.

Other features of the PIM4328P include protection against input transients, reverse polarity, over-temperature, over-current, input under-voltage and inrush current.

The module complies with RoHS requirement, has integral hot-swap functionality and hold-up charge, and discharge management.

The inputs include dual power feeds with OR'ing functionality and 'enable' signalling.

MTBF is 1.8 million hours (Telcordia SR-332 Issue 2, Method 1) and meets safety requirements according to IEC/EN/UL 60950-1.
