• Universal Input: AC 110V (USA/Canada) or 220V (EU/UK) selectable via internal switch
• Aluminum Enclosure: Honeycomb ventilation design for superior heat dissipation
• Fanless & Silent: No cooling fan — operates quietly in any environment
• 3 Output Channels: Three output ports, each rated up to 20A (total not to exceed 240W)
• Advanced Protection: Overload, over-voltage, thermal, and short-circuit protection
• EMI Filtered: Synchronous rectifier smart chip minimizes electromagnetic interference

Specifications

Compatible Applications

• LED strip lights and LED grow lights
• 3D printers (Ender, Creality, etc.)
• CCTV security cameras and DVR/NVR systems
• Ham radio transceivers and amateur radio equipment
• Car audio amplifiers and home audio systems
• Wireless routers, ADSL modems, and network hubs
• LCD monitors and audio/video equipment

Usage Recommendations

For optimal lifespan, keep power draw below 80% of max capacity (192W). Set the internal voltage switch to 110V for USA/Canada or 220V for Europe before first use. Professional installation by a licensed electrician is strongly recommended. Do not remove the cover — high voltage present inside.
