Astro 12V 4A AC/DC Power Adapter — High-Performance Replacement Supply ⚡📡

The Astro AC/DC Power Adapter is a premium high-current power solution designed for stability and longevity. Delivering a robust 4A (4000mA) output at 12V, this adapter provides a total of 48W of continuous power, making it the ideal replacement for performance-heavy electronics like satellite decoders, high-end routers, and LED lighting systems.

Engineered with a professional 3-pin "Clover" (IEC C6) inlet, it ensures a grounded, secure connection to minimize electrical noise and enhance safety.

Key Performance Features

• High-Capacity 4A Output: Provides a powerful 4.0A current, ensuring peak performance for high-draw devices and preventing system crashes caused by under-powering.

• Universal Input Voltage: Operates seamlessly on a global range of 100–240V AC, making it compatible with various electrical grids.

• Secure 2.1mm DC Tip: Equipped with a precision-molded right-angle DC plug (5.5mm outer / 2.1mm inner diameter) to provide a space-saving and secure electrical contact.

• Grounded IEC C6 Inlet: Utilizes a standard 3-pin "clover leaf" socket for a reliable grounded connection, protecting your sensitive electronics from power surges.

• Built-in Ferrite Core: Features an integrated EMI suppressor on the cable to filter out high-frequency noise and ensure clean power delivery.

• Safety Certified: Fully compliant with UL, CE, CCC, FCC, and GS standards for trusted, industrial-grade reliability.

Technical Specifications

• Input: 100–240V ~ 50/60Hz, 1.2A.

• Output: DC 12V ⎓ 4.0A (48W Max).

• DC Plug Size: 5.5mm (OD) / 2.1mm (ID).

• Polarity: Center Positive (+).

• Input Interface: 3-Pin IEC C6 (Clover Leaf).

Typical Applications

• Satellite & Cable Decoders: Specifically designed to meet the high-demand power needs of Astro decoders and similar set-top boxes.

• CCTV Systems: Perfect for powering multiple security cameras or high-resolution DVR/NVR units.

• Networking Gear: Ideal for enterprise-grade routers and network switches that require higher amperage than standard wall adapters provide.

• Monitors & Displays: A reliable replacement power brick for LED/LCD monitors requiring 12V 4A input.

Top 3 Customer Questions & Concerns 🙋‍♂️

⚡ Can I use this for a device that only needs 12V 2A? Yes. Amperage is "pulled" by the device, not pushed by the adapter. This 4A capacity unit will safely provide exactly what your device needs while running cooler and under less stress than a lower-rated unit.

🛡️ Does this adapter come with the wall power cord? This model features an IEC C6 clover leaf inlet. While often sold as the main adapter unit, you will need a standard 3-pin clover leaf power cord to connect it to your wall outlet.

🔌 Will the tip fit my device? The DC tip is the industry-standard 2.1mm internal diameter. If your device uses the common 5.5mm outer/2.1mm inner port, this will provide a perfect, snug fit.
