380V High-Frequency Switching Power Supply for Industrial Ethernet

380V high-frequency switching power supplies provide efficient, compact, and reliable power for industrial Ethernet devices, supporting high performance and protection standards. OverviewHigh-frequency switching power supplies designed for industrial Ethernet applications convert 380V AC or DC input into stable DC output suitable for switches, routers, and industrial computing devices. These power supplies are optimized for high efficiency, low ripple, and precise voltage/current regulation, making them ideal for automation and industrial networking environments.

Key Features

Input Voltage: Typically 380V AC or DC, with some models supporting a range of 380–500V AC or ±10% tolerance for DC. Output Voltage and Current: Common outputs include 24V DC at 40A (960W) for industrial devices, with adjustable voltage/current options in high-frequency models.

High-

Frequency Switching: Uses PWM control and IGBT technology for high efficiency (up to 90%), compact size, and low power loss. Protection Features: Overload, short-circuit, and over-temperature protection with automatic or manual restart. Mounting: DIN-rail mountable for easy integration into industrial panels.

Environmental Tolerance: Operating temperatures from -40°C to +85°C in some models, with derating at higher altitudes. Compliance: Meets CE, UL, cULus, IEC, and other industrial safety standards.

Applications

Industrial Ethernet Switches and Routers: Provides stable power for PoE-enabled switches and industrial gateways. Automation Systems: Powers PLCs, sensors, and actuators in factory automation.

High-

Precision Industrial Equipment: Supports devices requiring low ripple and high stability, such as measurement and control systems.

Product Examples

Schneider Electric Regulated Switch Mode Supply: 380–500V AC input, 24V DC output at 40A, 960W, DIN-rail mountable, with full protection and compliance certifications.
