With a compact size of 85×55×30mm, its reasonable volume does not crowd the desktop space, adapting to various fixed scenarios such as offices, computer rooms, and home desktops. Backed by an IP44 dustproof and waterproof rating, it can operate stably in different indoor environments (dry, humid, etc.), providing continuous and reliable DC power for various devices and completely solving pain points such as unstable power supply and incompatible interfaces for desktop equipment.

V. Core Specifications

VI. Safety Protection System (Compliant with Global Standards)

Over-Temperature Protection: Built-in high-sensitivity temperature sensor, automatically cuts off power when internal temperature reaches ≥60℃, preventing device damage caused by overheating during long-term desktop use and adapting to special scenarios such as closed cabinets.

Over-Voltage Protection: Automatically shuts down if output voltage exceeds 115% of the rated value, protecting precision desktop equipment such as desktop computers and industrial computers.

Over-Current Protection: Limits current to 120% of the rated value via intelligent current-limiting technology, avoiding short-circuit risks caused by device overload or malfunctions.

Short-Circuit Protection: Millisecond-level response (≤10ms), instantly cuts off the power loop upon short-circuit detection, eliminating fire hazards and ensuring safe desktop use.

Surge Protection: Equipped with CCC/CE/FCC-certified surge suppressors to absorb grid voltage spikes, adapting to complex power supply environments such as old office areas and industrial power grids.

Leakage Protection: Detects tiny leakage currents (0.1mA) via CCC-compliant leakage detection technology and activates protection, preventing electric shocks and device malfunctions.

VII. Core Advantages (Focus on Desktop/Fixed Use Scenarios)

Global Voltage Compatibility, Universal for Fixed Locations100-240V wide voltage input, compatible with fixed power grids in countries worldwide. Whether in offices, computer rooms, or industrial workshops, no additional adapters are needed-plug and play, meeting the multi-scenario procurement needs of enterprises.

Reasonable Size Design, Space-Saving on DesktopsOptimized desktop-specific structure with a compact size (85×55×30mm). It can be placed vertically or horizontally without occupying valuable desktop workspace, and is easy to embed in equipment cabinets or workbench corners for neater storage.

Industrial-Grade Durability, Suitable for Long-Term Fixed UseV0-grade flame-retardant shell self-extinguishes within 10 seconds.

Global Compliance Certifications + Energy-Saving, Reliable for Enterprises/FamiliesCertified by CCC, CE, FCC, and other global mainstream certifications, ensuring compliance for enterprise procurement and cross-border sales, with smooth customs clearance. ≥85% conversion efficiency + ≤0.3W standby power consumption saves significant electricity costs for long-term fixed use, responding to low-carbon environmental policies and balancing economy and social responsibility.

Core Selling Points (For Chinese Buyers, Value-Deepened)

Global Voltage Compatibility & Compliance Certifications for Fixed Use

100-240VAC ±10% wide voltage input, seamlessly compatible with China's 220V/50Hz grid, US 110V/60Hz, Europe 230V/50Hz, and other global fixed power standards-no plug adapters required for fixed scenarios. Fully certified with mandatory domestic certifications (CCC safety, EMC electromagnetic compatibility, GB 20943 energy efficiency) for Chinese market sales, plus international certifications (CE, FCC, RoHS). Provides complete certification dossiers for domestic sales, cross-border customs clearance, and overseas market inspections, eliminating compliance risks for enterprises purchasing for fixed installations (offices, workshops, computer rooms).

Stable Power Supply for Long-Term Fixed Operations

Built-in high-precision voltage stabilization circuits and low-ripple technology (≤120mV), with ±1% voltage precision to handle ±15% grid fluctuations. Ideal for unstable power environments such as rural areas in China, industrial parks, and old urban districts. The standard CN Type I plug (GB 1002 compliant) fits domestic sockets directly, supporting 24/7 continuous operation for devices like surveillance systems, industrial controllers, and office equipment-solving the pain point of unstable power supply for long-term fixed use.

Multi-Scenario Adaptability for Fixed Installations

Operating temperature range of -40℃ to +50℃ adapts to diverse fixed environments: withstanding low temperatures in northern China's workshops, high humidity in coastal industrial zones, and high temperatures in southern computer rooms. IP44 dustproof and waterproof rating supports indoor fixed use (office desktops, smart home hubs) and outdoor fixed installations (outdoor surveillance cameras, street-side advertising players, industrial field equipment). Breaks the indoor-only limitation of traditional desktop adapters, meeting the multi-environment fixed power needs of Chinese enterprises and cross-border sellers.

Energy-Saving & Cost-Reduction for Enterprise Procurement

Boasts ≥85% energy conversion rate and ≤0.3W standby power, exceeding GB 20943 energy efficiency standards and international energy-saving requirements. For commercial users with 24/7 operations (e.g., shopping mall displays, data center equipment, 24-hour monitoring systems), it reduces annual electricity costs by 15-20% compared to ordinary adapters. Aligns with China's "dual carbon" policy, helping enterprises enhance their environmental image in domestic and overseas markets while cutting long-term operational costs.
