48V 20A Power Supply

Description

This product specification outlines a high-performance 48V 20A DC Power Supply, designed for demanding industrial, telecommunications, and automation applications.

Product Overview

This power supply is a robust, switch-mode unit capable of providing a steady 960W of power output. It is engineered for high efficiency, reliability, and compact integration into cabinets or rack-mounted systems.

Key Technical Specifications

Core Features & Benefits

• • High Power Density: Provides a significant 960W output in a relatively small form factor, saving valuable space in equipment enclosures.

  • Active PFC (Power Factor Correction): Reduces harmonic distortion and increases energy efficiency, making it compliant with global power regulations.

  • Comprehensive Protection Suite:

    • Short Circuit Protection: Automatically recovers after the fault is cleared.

    • Over-Voltage Protection (OVP): Shuts down the unit if output voltage exceeds safety thresholds.

    • Over-Load Protection: Limits current to prevent component damage.

    • Over-Temperature Protection: Internal sensors trigger a shutdown if the unit overheats.

  • High Reliability: Designed with high-quality electrolytic capacitors to withstand harsh industrial environments and vibration.

Common Applications

• Industrial Automation: Powering PLCs, sensors, and actuators.

• Telecommunications: Providing clean DC power for base stations and network hardware.

• LED Lighting: Reliable power for large-scale LED arrays.

• Electric Motor Drives: Supporting DC motors and motion control systems.

• Battery Charging: Used as a stage in custom battery charging systems (when current limiting is managed).

Installation & Safety Notes

1. Ventilation: Ensure at least 50mm of clearance around the ventilation holes to allow for proper airflow.

2. Wiring: Use appropriate wire gauge (AWG) based on the 20A current draw to prevent voltage drop and overheating of cables.

3. Grounding: The chassis must be properly grounded to the earth terminal to ensure user safety and minimize electromagnetic interference (EMI).

4. Derating: Note that many units require “derating” (reducing the maximum load) when operating at extreme high temperatures or low input voltages. Refer to the specific manufacturer’s derating curve.
