40W OVC IV Regulated Output PCB Mount AC-DC Encapsulated Power Module

ATCW40 Series

40W Board Mount AC to DC Industrial and ITE Power Conversion (Module) - The Industry’s First Ultra-Compact OVC IV Power Module

The ARCH ATCW40 sets a new benchmark in the 40W AC-DC power module category, being the only module of its kind to offer Over-Voltage Category IV (OVC IV) compliance in an ultra-compact form factor. While most competitors only reach OVC II or III and cap input voltages at 305VAC, the ATCW40 power module goes further with an expanded 90–330VAC input range—designed specifically for direct connection to primary power sources such as main distribution panels, smart meters, and power grid equipment.

Compact Size. Unmatched Capability

Despite its powerful protection profile, the ATCW40 power module maintains a remarkably compact size, making it easier to integrate into space-constrained designs—something rarely seen in high-isolation, high-category modules. With reinforced 5700VAC isolation, Class II compliance, and full EMC compliance without requiring any external components, the ATCW40 offers a multi-layered safety and design advantage unmatched by other 40W modules on the market.

Certified for Global and Harsh Environments

Built for tough conditions, the ATCW40 power module operates reliably across a wide -40°C to +70°C temperature range and at altitudes up to 5000m. With < 0.1W no-load power consumption, efficiency up to 89%, and full EN / UL / IEC 62368-1 certification, it delivers performance that's both energy-efficient and globally deployable—without sacrificing safety.

Ideal for High-Risk and Mission-Critical Applications

The ATCW40 power module's unique OVC IV compliance, high isolation voltage, and wide input range make it a perfect fit for critical infrastructure, renewable energy systems, factory automation, smart grid interfaces, and other surge-prone or unregulated environments where conventional modules fall short. When your design demands higher standards, the ATCW40 power module delivers—with a size, certification, and performance edge that no other module can match. Choose ARCH for innovation that fits where others can't—and protects where others won't.
