Description
Huawei Rectifier EPW30-48A
The Huawei Rectifier EPW30-48A is a high-density, hot-swappable rectifier module designed for telecommunications and industrial power systems. It converts AC input to a regulated -48V DC output, typically used in small SPC exchanges, access networks, and mobile communication equipment.
Technical Description for Huawei Rectifier EPW30-48A
The rectifier utilizes soft-switching technology to achieve high reliability, efficiency, and low noise emissions.
- Parallel Operation: Multiple modules can be connected in parallel to share loads, controlled via active current sharing.
- Hot-Swappable: The module is designed for online removal and insertion without interrupting system operation.
- Intelligent Monitoring: It features an internal microprocessor for real-time monitoring and status reporting via RS485 to a supervisory unit.
- Thermal Management: Built-in speed-controlled fans provide forced-air cooling with a forward-intake and rear-exhaust design.
