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 Feature Specification Output Voltage 48V DC (typically adjustable $\pm$10%) Rated Current 20A Rated Power 960W Input Voltage 90–264V AC (Universal Input) Efficiency Typically >90% Operating Temp -20°C to 60°C Cooling Method Built-in smart cooling fan 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 Ventilation: Ensure at least 50mm of clearance around the ventilation holes to allow for proper airflow. Wiring: Use appropriate wire gauge (AWG) based on the 20A current draw to prevent voltage drop and overheating of cables. Grounding: The chassis must be properly grounded to the earth terminal to ensure user safety and minimize electromagnetic interference (EMI). 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.
