  • New series of Power Interface Modules deliver on promise of greater power handling
  • Extensive range of energy monitoring functionalities via the PMBus
  • New modules handle up to 20A across 36V to 75V input voltage range

Ericsson has announced an industry first with a new series of Power Interface Modules that save board space for core processing functions and enable system architects to design equipment with energy monitoring features, enabling the use of optimization algorithms to reduce overall board power consumption. The new PIM4800PI series of Power Interface Modules is able to sustain a current of 16.5A across the full telecommunications input voltage range of 36V to 75V, resulting in an output power of 660W to 890W with built-in digital monitoring via the PMBus. In addition, the new modules can provide up to 20A continuous current in systems where there are no input-voltage transients or are very limited.

"The demands for increasing computing power and signal-handling capacity in the ICT (Information and Communications Technology) industry means higher power needs per system board," said Patrick Le Fèvre, Marketing and Communications Director, Ericsson Power Modules. "However, at the same time, board real estate together with energy management and power optimization have became strategically important factors for systems designers. This new product benefits from Ericsson’s extensive experience in high-efficiency topologies, board power optimization technologies and the development of products incorporating digital interfaces and PMBus capabilities.

The first in this new series, the PIM4820BPD is a Power Interface Module that enables monitoring via the industry-standard PMBus and includes a DC/DC power module converter with 2250 VDC isolation and an adjustable output voltage of 0.85V to 7.0V within a power range of 15W/5A. While aimed primarily at high-end equipment applications, the PIM4820BPD allows the optimisation of board space and delivers board-level control of power consumption making the product also highly attractive for a broad range of ICT applications overall.
