Ensuring Uninterrupted Power for Telecom Networks

In telecom infrastructure, reliability is non-negotiable. Telecom battery systems play a critical role in this, providing backup power during grid failures to keep networks online. These systems typically consist of interconnected rechargeable battery modules managed by a battery management system (BMS) that ensures optimal charging and discharging cycles. This maximizes battery lifespan and ensures consistent power delivery during outages, often for several hours.

Standard voltage levels range from 48 V to 96 V; 48 V systems are the most common due to their compatibility with telecom equipment and efficient energy transfer.

A key component of the battery charger is the MUR2040CT by Diotec Semiconductor. This dual super-fast, highly efficient rectifier is designed with a common cathode configuration for push-pull converters. The MUR2040CT comes in the TO-220AB package and offers:

  • 400V reverse voltage for a strong safety margin
  • 35 ns switching time to minimize power loss

From BMS to rectifiers, every detail matters in maintaining a robust and fail-safe power supply.
