ARCH AC-DC Encapsulated Power Module ANCH50 with Screw Terminal A2

50W Compact AC-DC Power Module with Dual Safety Certifications

ANCH50 Series

Smart, Space-Saving Power for Household, ITE & Industrial Designs — No Extra EMC Parts Needed

The ARCH ANCH50 is a next-generation 50W ultra-compact AC-DC power module, designed to deliver exceptional performance, enhanced safety, and greater application flexibility. As an upgraded version of the ANC50, the ANCH50 not only inherits all the benefits of the original—such as high efficiency (up to 90%) and < 0.1W no-load power consumption—but also offers expanded input voltage range (90–305VAC) and reinforced isolation up to 4000VAC, meeting more demanding application requirements.

Dual Safety Certifications for Greater Application Flexibility

Certified to UL / IEC / EN 62368-1, IEC / EN 60335-1, and IEC / EN 61558-2-16, the ANCH50 power module stands out with dual compliance for both household and ITE applications. This allows it to be seamlessly deployed in smart home systems, consumer electronics, industrial controls, and commercial automation, making it an ideal choice for designs that require multi-sector safety approvals.

Flexible Mounting Options – PCB or Chassis

Designed for smooth system integration, the ANCH50 power module supports both direct PCB mounting and chassis mounting with screw terminal blocks. For installations where PCB mounting is not feasible, ARCH offers a screw terminal version as an option, providing installation flexibility to suit different mechanical or modular requirements.

Reliable, Space-Saving, and EMC Compliant

The ANCH50 power module delivers robust protection, including Over Voltage Protection (OVP), Over Power Protection (OPP), and short-circuit protection, ensuring stable performance in modern home or industrial power environments. The power module is EMC compliant without requiring additional external components, helping engineers streamline system design and reduce BOM cost.

More protection. More certification. More flexibility.

With its enhanced specs and dual safety compliance, the ANCH50 power module is the ultimate 50W power solution—engineered to bridge household, commercial, and industrial needs in one compact module.
