Taconic Prototype PCB for Power Supply

Compact & Certified PCB Mounted AC/DC Power Supplies

Modern electronic assemblies are often designed to be very power efficient, so that they only draw a few watts of power. For such applications, RECOM has developed a wide range of Class II isolation 1W-10W AC/DC power supply modules for PCB mounting, designed to withstand PCB wave soldering processes. These board mount AC/DC converters are complete power supplies, requiring no external components to fully meet safety and EMC regulations without an earth connection. They are offered with a 85VAC to 264VAC or 305VAC universal input voltage range for worldwide use. Notably, the RAC05-K/480 series can additionally operate from phase-to-phase with its extended 85VAC to 528VAC input range.

Benefits of Integrating PCB-Mount Power Solutions

Opting for PCB mount AC/DC power supplies offers key design and manufacturing advantages. Their compact form factor saves board space, contributing to smaller end-products. Direct board mounting simplifies assembly, reduces wiring, and can enhance system reliability. Modules designed for wave soldering also boost manufacturing efficiency for these low power AC/DC solutions.

Advanced Design for Enhanced Performance and Versatility

RECOM uses the latest advances in switching controllers, topologies, and components to create power supplies with up to double the power density than previously possible without sacrificing safety, reliability, efficiency, or performance. The majority of AC/DC power supplies from RECOM are internationally certified to UL/IEC/EN standards for industrial (EN/IEC/UL 62368-1), measurement, control, and laboratory (EN/IEC/UL 61010-1), and household (EN/IEC/UL 60335-1) applications, with CB Reports available. This comprehensive certification makes them suitable for a broad spectrum of applications including industrial controls, test and measurement equipment, and building automation systems.

Critical Features for Optimal Performance and Reliability

When selecting a low power AC/DC module, consider these critical features beyond certifications and input ranges:

• Low Standby Power: Crucial for energy-efficient, "always-on" applications to meet eco-design standards.
• Integrated Protections: Essential safeguards like overcurrent, short-circuit, and over-temperature protection for the module and load.
• Robust Packaging: Encapsulated board mount AC/DC power units offer durability against environmental factors like dust and moisture.
• Class II Isolation: This design simplifies installation (no earth connection) and enhances safety where grounding is challenging.

Diverse Applications for Low-Power AC/DC Modules

These versatile 1W to 10W AC/DC power supply modules suit numerous applications. They are commonly used in industrial controls (e.g., sensors, local MCUs), test and measurement equipment (portable/benchtop devices), and building automation systems (smart controls, security). Additionally, these universal input AC/DC modules power many Internet of Things (IoT) devices, smart home/office systems, and serve as auxiliary power sources in larger equipment.
