48 VDC Telecom Rectifier
Product description The 48 VDC Telecom Rectifier provides reliable DC power for telecommunications infrastructure. It converts AC mains power into a controlled, regulated 48 VDC supply for telecom equipment and manages charging of the connected battery bank. Its modular design allows capacity to scale with demand and supports service continuity during maintenance. Parallel rectifier modules provide load sharing and redundancy for high availability in critical communications systems. Digital monitoring and control allow output voltage, current, system status and alarms to be tracked. Remote monitoring and communication options can be integrated according to the application. The compact 19-inch rack design integrates into telecom cabinets and standard equipment racks.

Role in the system and operating principle
Operating principle
Each module converts AC energy into a regulated DC output. The controller manages module load sharing, the battery charging regime, alarms and remote communications.
Maintenance and lifecycle
Hot-swap modules reduce maintenance time. Fans, filters, connections, control software and battery performance are monitored at planned intervals.
APPLICATIONS
Engineering for the duty profile.
- Telecommunications and data infrastructure
- Substations
- Rail communications
- Industrial control
- Distributed DC power
