AC to DC Voltage Converter AC 12V to 5V 3A 15W

Description

Rugged AC to DC Converter for Tough Conditions

🔧 Built to Last – Indoors or Outdoors

This compact AC to DC converter features a fully sealed IP68 waterproof housing and flame-retardant ABS shell, built to endure temperatures from -20°C to +65°C. With over 50,000 hours of reliable operation, it’s ideal for automotive, marine, or outdoor applications.

⚙️ Efficient 5V Power You Can Rely On

Delivers a stable 5V output (±1%) from fluctuating 10–40V DC or 10–26V AC inputs. High-efficiency 92% peak performance and up to 3A continuous current make it perfect for powering sensors, cameras, and other demanding 5V devices.

🛡️ Comprehensive Safety Mechanisms

This converter doesn’t just deliver power—it defends your system with three layers of protection:

• Short-circuit shutdown
• Reverse polarity protection
• Thermal overload prevention

Additional built-in safeguards include a fast-acting 5A fuse and 600W TVS surge suppression to absorb voltage spikes. Automatic load sensing helps detect and respond to current overloads before they cause damage.

Detailed Specifications

🧠 Smart Engineering Inside

• Core Architecture: Employs a high-performance synchronous buck regulator (based on LM25116-Q1) that reduces switching loss and boosts power delivery efficiency.
• Thermal Optimization: Features a multilayer PCB with thick copper traces and heat-conducting vias to disperse heat efficiently.
• Certified Durability: Rigorously tested to automotive standards including ISO 16750-2 (vibration) and ISO 20653 (dust/water resistance).

🌡️ Adaptive Thermal Response

Equipped with real-time NTC thermal sensors, the system adjusts its output to prevent overheating—throttling at 75°C to avoid shutdown while maintaining performance. It also supports cold starts down to -40°C (optional pre-heat circuit available).

✅ Compliance & Warranty

• Insulation Rating: 1500V DC (non-isolated design)
• Certifications: Meets UL 60950-1 and EN 55032 Class B EMI standards for safety and electromagnetic compatibility.
• Warranty Coverage: Includes a 1-year manufacturer warranty and lifetime technical assistance.

🔌 Installation Guide

1. Check Compatibility: Ensure your power source falls within the 10–40V DC or 10–26V AC range.
2. Prepare Wiring: Strip 10mm of insulation from each 18–12 AWG wire.
3. Connect Leads:
   • Power In: Red (+)
   • Output: Yellow (+5V), Black (GND)
4. Secure Glands: Tighten included waterproof seals to prevent moisture ingress.

💡 Tip: For marine or solar applications, applying dielectric grease (not included) to the terminals enhances corrosion resistance.

Frequently Asked Questions

Q: Can this converter be connected directly to 220V AC?

⚠️ No. It requires a low-voltage AC or DC source (e.g., solar setup or automotive battery). You’ll need a step-down transformer for 220V AC sources.

Q: How do I know if my setup is within power limits?

➤ Add up all the device demands (5V × current). Example: 5V/2A for a camera and 5V/1A for a sensor = 15W total.

Q: Is it safe for use in medical or automotive electronics?

➤ Yes. EMI emissions are under 30dBμV at 3m, compliant with EN55032 Class B, making it suitable for sensitive environments.
