1. Product Introduction
The TH48D30NZ-S is a high-power-density, 1U compact switching power supply module specifically designed for communications and integrated power systems. It provides a stable 48V DC output up to 30A (1750W) and is compatible with both AC (176-264VAC) and DC (176-286VDC) input, offering exceptional flexibility. Designed to meet industry standards (DL/T 1074-2019), it features Modbus and proprietary protocol support via an RS-485 interface for easy system integration and intelligent control.
2. Product Advantages
Ultra-Compact & Versatile: 1U standard rack height saves significant cabinet space. Unique AC/DC dual-input capability provides deployment flexibility in diverse power environments.
High Efficiency & Low Standby Loss: Delivers high conversion efficiency (≥94%) with extremely low standby power consumption (≤5W), reducing overall energy costs.
Wide Environmental Tolerance: Reliable operation across a broad temperature range (-10℃ to +40℃ at full load) with intelligent derating at high temperatures and robust protection against dust and moisture.
Intelligent & Safe: Supports remote monitoring and control ("Three-Remote" functions), features comprehensive protections (over-voltage, short-circuit, over-temperature), and allows for safe hot-swapping during maintenance.
3. Application Scenarios
This module is the ideal power core for space-conscious and reliable DC power systems:
Communications Infrastructure: Base stations, data transmission equipment, and core network rooms requiring compact and efficient 48V power.
Integrated Power Systems (UPS): As a key component in DC backup systems or integrated AC/DC power cabinets for industrial control and monitoring.
General-Purpose Compact Systems: Any application demanding high power density, reliable 48V output, and flexible input options in a standard 1U form factor.

Load Rating |
Continuous operation at 100% of rated output current (Load Level I) |
|
|
Automatic Current Limiting |
Once the output current reaches the set current limit, the module automatically switches to constant current operation, preventing any further increase in output current. |
|
|
Short-Circuit Protection |
Short-Circuit Protection: When an output short-circuit occurs, the module enters a short-circuit state. It does not operate but prevents damage, and the module does not shut down |
|
|
Overtemperature Protection: After an overtemperature shutdown, the module automatically restarts approximately five minutes after the fault is cleared. |
