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.

Current Sharing Imbalance		±5%
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.
