AC to DC Converter 24V to 5V 3A 15W Voltage Converter

Description

AC to DC Voltage Converter – Durable, Efficient & Protected

This AC to DC voltage converter is engineered for tough environments. With military-grade durability, high efficiency, and intelligent protection, it ensures stable 5V power in automotive, marine, or industrial applications.

🛡️ Rugged & Weatherproof

Built with an IP68 waterproof, fully sealed design, the unit can operate submerged up to 1.5 meters for 30 minutes. The V-0 flame-retardant ABS housing handles temperatures from -20°C to +65°C. Its 50,000+ hour lifespan ensures long-term reliability in demanding settings.

⚡ High-Efficiency Output

Achieving up to 92% efficiency, it uses synchronous rectification for minimal energy loss. Despite input fluctuations (10–40V DC / 10–26V AC), it delivers a rock-solid 5V output (±1%). Supports 3A continuous and 3.5A peak loads—perfect for modern 5V electronics.

🔒 Comprehensive Protection

Triple protection against short circuits, overheating, and reverse polarity is built-in. A 5A quick-blow fuse and 600W surge suppression enhance safety, while automatic load detection avoids overcurrent damage. Designed for peace of mind in harsh environments.

Technical Specifications

🧠 Engineered for Performance

Powered by the LM25116-Q1 controller, the converter uses a synchronous buck topology and a multi-layer PCB with 2oz copper for optimal thermal flow. It meets ISO 16750-2 and ISO 20653 standards for vibration and ingress protection.

🌡️ Smart Thermal Management

An NTC sensor monitors temperature, throttling output at 75°C to prevent shutdown. The unit cold-starts at -40°C and supports an optional pre-heating circuit for extreme cold environments.

✅ Safety & Compliance

Features 1500V DC input-output isolation (non-isolated design), meets UL 60950-1 safety and EN 55032 Class B EMI standards. Backed by a 1-year limited warranty and lifetime tech support.

🔧 Installation Guide

1. Confirm input source is 10–40V DC or 10–26V AC
2. Strip 10mm insulation from 18–12 AWG wires
3. Connect:
   • Red = Input (+)
   • Yellow = 5V Output (+)
   • Black = GND
4. Tighten included gland nuts

💡 Tip: For marine/solar use, apply dielectric grease (not included) to prevent corrosion.

❓ FAQs

Q: Can this be used with 220V AC?
No, it needs a low-voltage input. Use a separate AC-to-DC converter for 220V.

Q: How to calculate load capacity?
Add up all 5V loads: e.g., 5V/2A + 5V/1A = 15W max.

Q: Is it safe for sensitive electronics?
Yes. With <30dBµV EMI at 3m (Class B), it’s suitable for automotive and industrial environments.
