Product Introduction
The TH48D30NZ-S-2 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.
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.
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.

Protection Features
- 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: 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.
