Voltruc DT1000 use in Telecom
Industry Background
Communication base stations, core network rooms, and access network equipment typically use –48V DC power supply, which demands high stability, intelligent monitoring, and robust battery management from the power system. With the rollout of 5G, increased equipment power consumption has introduced new challenges for power capacity and redundancy.
Core Requirements
- Stable –48V DC output with wide input voltage range to accommodate unstable grid conditions
- Comprehensive battery management (equalized/floating charging, temperature compensation)
- Remote monitoring and dry contact alarms (for unattended sites)
- High power density to save cabinet space
- Optional inverter function to power AC equipment
