The PIM4328P power interface module from Ericsson is optimised to simplify design in blade servers based on ATCA (advanced telecommunications computing architecture) systems. The company's low-EMI design rules ensure that minimal external filtering is required to meet the comité international spécial des perturbations radioélectriques Class B electromagnetic compatibility standards. The company claims that the module minimizes ripple and noise, simplifies the circuit design, without compromising on the performance. The module is based on the company's energy optimized platform, and operates over an input range from 36 to 75V. It sustains a permanent output current of 10A without forced airflow up to +70°C and up to +90°C with 2.0m/s. The output power of the module is 390W at a minimum input of 39V and up to 540W when the input is 54V. The module delivers 99% efficiency at 300W output, and maintains high standards of dynamic and load step performance, which is required in ATCA equipment.
The module also protects against input transients, reverse polarity, over-temperature, over-current, input under-voltage, and inrush current. It complies with RoHS specifications, and has integral hot swap functionality and hold-up charge and discharge management. The inputs include dual power feeds with OR'ing functionality. The MTBF of the module is 1.8 million hours and meets safety requirements according to IEC/EN/UL 60950-1. The module is suitable for any industrial, telecommunications and data communications application that employ distributed power architecture.
