Accessories

1. Overview

External/internal power supply accessories refer to components that enable power delivery, management, and protection for electronic systems. These accessories ensure stable operation, efficiency, and safety in applications ranging from consumer electronics to industrial machinery. Modern technology relies on these accessories to meet energy efficiency standards, reduce downtime, and support complex power architectures.

2. Main Types and Functional Classification

Type	Function Features	Application Examples
External Power Adapters	AC-DC conversion, portability, over-voltage protection	Laptops, medical devices
Internal Power Modules	Integrated DC-DC conversion, compact form factor	Servers, networking equipment
Power Distribution Boards	Multi-channel output, load balancing	Data centers, industrial automation
Battery Backup Systems	Uninterruptible power supply (UPS), energy storage	Emergency lighting, critical infrastructure
Power Management ICs	Digital monitoring, dynamic voltage scaling	Smartphones, IoT devices

3. Structure and Components

Typical components include:

Metal/Plastic Housing (thermal management and EMI shielding)
PCB with Power Semiconductors (MOSFETs, rectifiers)
Transformer/Inductor Arrays
Connectors (USB-C, PCIe, or proprietary interfaces)
Thermal Pads/Sinks for heat dissipation
Protection Circuits (OCP, OVP, SCP)

4. Key Technical Specifications

Parameter	Importance
Input Voltage Range (90-264V AC)	Ensures global compatibility
Efficiency Rating (80 PLUS Certification)	Reduces energy waste
Output Ripple Noise (<30mV)	Protects sensitive electronics
Operating Temperature (-40 C to +70 C)	Determines reliability in extreme conditions
Safety Certifications (UL/CE/IEC 62368)	Compliance with regulatory standards
MTBF (Mean Time Between Failures) >100,000 hours	Measures long-term reliability

5. Application Fields

Information Technology: Server racks, storage systems
Healthcare: MRI machines, patient monitors
Industrial: CNC machines, robotics

7. Selection Guidelines

Key considerations:

Power Requirements (calculate peak/continuous load with 20% margin)
Form Factor Compatibility (ATX, SFX, or custom mechanical dimensions)
Environmental Conditions (humidity, vibration, altitude)
Certification Needs (energy efficiency standards, industry-specific compliance)
Redundancy Features (N+1 configuration for mission-critical systems)

Case Study: A semiconductor manufacturing plant selected IP67-rated power distribution units with active PFC to reduce harmonic distortion in high-vibration environments.

8. Industry Trends

Emerging trends include:

Gallium Nitride (GaN) devices enabling 98%+ efficiency
Smart power systems with IoT-enabled monitoring
Modular designs for rapid scalability
48V DC ecosystems for data centers
Advanced thermal management using phase-change materials

Market growth driven by EV charging infrastructure and renewable energy integration requirements.
