ATCW40 AC-DC Power Module is ultimate choice for smart grid applications

ARCH Electronics Corp. proudly announces the launch of the ATCW40, a next-generation 40W AC/DC power module that redefines industry benchmarks with Over-Voltage Category IV (OVC IV) rating—the highest level of electrical protection.

Engineered for OVC IV — Unmatched Surge Protection

The ATCW40 power module is designed for direct connection to power distribution systems, making it ideal for smart meters, energy management systems, and grid controllers. With a wide input range of 90–330VAC and reinforced 5700VAC isolation, the power module offers robust protection against high-energy surges. As one of the very few standardized OVC IV power modules on the market, ATCW40 eliminates the need for custom designs or external components for surge protection, enabling faster, safer, and more cost-effective deployment.

 

Compact Form, Industrial-Grade Reliability

Measuring only 2.52” x 1.8” x 0.93” and weighing 125g, the ATCW40 AC/DC power module packs robust performance into an ultra-compact design. Key specifications include:

  • Reinforced isolation: 5700VAC
  • Class II insulation: No earth ground required
  • Wide operating temperature: –40°C to +70°C (derating)
  • Leakage current: ≤0.25mA
  • EMC compliance: EN 55032 Class B / EN 55035 — no external components required

 

Energy Efficient & Globally Certified

With 89% efficiency and <0.1W no-load power consumption (excluding 48V model), the ATCW40 AC/DC power module meets modern energy-saving directives and performs reliably in always-on systems. The power module is certified to UL / IEC / EN 62368-1 safety standards, with EMI/EMS compliance for global deployment.

 

Ideal for Harsh-Environment Applications

The ATCW40 AC/DC power module is the smart choice for:

  • Smart Grid & Smart Metering
  • Energy Monitoring & IoT Gateways
  • EV Infrastructure & Charging Modules
  • Building Automation & Control Panels
  • Remote or Outdoor Power Systems

 

Powering the Future of Energy

With the launch of the ATCW40 AC/DC power module, ARCH eliminates the need for costly custom OVC IV solutions, offering an off-the-shelf module that combines safety, performance, and compactness. It’s the power module of choice for engineers building the next generation of sustainable, intelligent infrastructure.
