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

Description

AC to DC Voltage Converter – Highlights & Features

🔧 Ruggedized for Extreme Environments

Engineered with full encapsulation and rated IP68, this converter handles tough environments—submersible up to 1.5 meters for 30 minutes.
The V-0 rated flame-retardant ABS enclosure offers superior resistance to extreme temperatures ranging from -20°C to +65°C.
Automotive-grade components ensure an impressive 50,000+ hours of mean time between failures, making it suitable for mission-critical use.

⚙️ Optimized for High-Efficiency Power Output

Utilizing synchronous rectification, this unit achieves up to 92% efficiency at peak load.
It delivers a stable 5V output with ±1% voltage tolerance, regardless of input fluctuations within 10–40V DC or 10–26V AC ranges.
Capable of providing 3A continuous current and handling up to 3.5A peak, it’s ideal for power-hungry devices.

🛡️ Built-In Intelligent Protection

Equipped with a trio of automatic protection systems—short-circuit, reverse polarity, and over-temperature shutdown.
A fast-acting 5A fuse and integrated TVS diode (600W) safeguard against surges.
Smart load detection ensures the system avoids overcurrent stress, protecting both the converter and connected devices.

Technical Overview

Precision Engineering Inside

🧠 Core Circuitry & Architecture

Based on a synchronous buck topology, the converter leverages the LM25116-Q1 automotive PWM controller to reduce switching losses.
A multilayer PCB with 2oz copper and thermal vias ensures efficient heat distribution and long-term performance.
The unit has passed ISO 16750-2 vibration and ISO 20653 ingress protection standards, confirming its robustness in real-world use.

🌡️ Adaptive Thermal Management

Temperature is continuously monitored via an NTC sensor, with a dual-path heat dissipation system maintaining safe operation.
Rather than shutting down, the unit throttles automatically above 75°C to preserve functionality.
Cold-start capable down to -40°C, and supports optional pre-heating for ultra-low temperature environments.

Certifications & Compliance

• Dielectric Strength: 1500V DC input-output (note: non-isolated)
• Safety Compliance: Meets UL 60950-1 and EN 55032 Class B EMI standards
• Warranty: Includes 1-year limited warranty and lifetime tech support

Quick Installation Guide

Step 1: Confirm your input power source is within the 10–40V DC or 10–26V AC range
Step 2: Strip 10mm of insulation from 18–12 AWG wires
Step 3: Use lever terminals to connect:

• Input: Red (+)
• Output: Yellow (+5V), Black (GND)
  Step 4: Tighten included waterproof gland nuts
  💡 Pro Tip: Apply dielectric grease (not included) for enhanced moisture protection in marine or solar installations

Frequently Asked Questions

Q: Can this replace a standard 220V AC wall adapter?
❌ No. This converter requires a regulated low-voltage DC/AC input like a battery or solar panel. A separate step-down converter is needed for 220V AC.

Q: How do I calculate the required power?
✅ Add up the total load (5V × total current). For example, a 5V/2A camera and a 5V/1A sensor require a combined 15W.

Q: How’s the EMI performance?
📡 It emits less than 30dBµV @ 3 meters, complying with EN55032 Class B—making it safe for use in sensitive applications like automotive or medical equipment.
