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.
