Product Specifications
The following table provides the main product information. Detailed electrical limits and communication interfaces should be confirmed against the official TH48T75NZ-S datasheet.

Product Advantages
1. High Efficiency, Lower Energy Consumption
With peak conversion efficiency of ≥97.5%, the TH48T75NZ-S reduces energy losses during AC-to-DC conversion. Lower power losses also help reduce heat generation and cooling requirements in telecom equipment rooms.
2. Wide Input Voltage Range
Supports 85–300VAC or 80–420VDC input, allowing the module to operate across different power supply conditions. This flexibility makes it suitable for telecom sites with varying input voltage environments.
3. Hot-Swappable Modular Design
The module supports hot-swap replacement, allowing maintenance personnel to replace an individual rectifier without shutting down the entire power system, when installed in a compatible system.
4. Intelligent Monitoring and Communication
Supports Modbus communication for integration with compatible monitoring controllers. Operators can monitor operating conditions and improve the efficiency of power system management.
5. Reliable Parallel Operation
Multiple rectifier modules can operate in parallel with current sharing. Combined with an N+1 redundant configuration, the system can maintain power supply continuity when one module requires maintenance, provided sufficient redundant capacity is available.
6. Durable Structure and Forced-Air Cooling
The reinforced metal front panel and fan cooling design help improve mechanical durability and heat dissipation, supporting stable operation in demanding environments.
