Ericsson Power Modules’ PIM4610PD is an extension of its 3E* Power Interface Module (PIM) quarter-brick footprint range, for blade server applications based on ATCA and PICMG 3.7 systems. The module is also suited to server and storage systems in any industrial, telecom and data communications application that employs either distributed power or intermediate bus voltage architectures.
Minimal external filtering is needed to meet the CISPR Class B EMC standards required for Information and Communications Technology systems. Ripple and noise characteristics have been minimised, while circuit design has been simplified leading to reduced component count and system costs without compromising performance. Itoperates over an input range of 36V to 75V and delivers 864W with a 54V input, 768W at 48V, and 600W at 37.5V. Efficiency is up to 98.8% at 600W for the main unit.
The PIM also offers built-in digital monitoring and energy-monitoring functionalities via its I ²C/PMBus interface. Other features of the PIM4610PD include: protection against input transients, reverse polarity, over-temperature, over-current, input under-voltage and inrush current. The PIM has a configurable feature that enables a well-controlled shutdown procedure. The feature enables de-assertion of the Power Good pin when it determines that input power is below a certain level, for protection of CPUs and FPGAs.
The module also has integrated hot-swap functionality and hold-up charge and discharge management. The inputs also include dual power feeds with OR’ing functionality and ‘enable’ signalling. Further specifications include: management power output of 3.3V and up to 7A; an MTBF of 2.66 million hours, according to Telcordia SR-332 Issue 2, Method 1, and isolation of 2250Vdc, which meets the latest IEC/EN/UL62368-1 safety standard.
