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. |
