36W Open Frame Power Supply 12V 3A for Industrial Control Boards and Embedded Systems

36W Open Frame Industrial Power Supply: 12V 3A High-Density Solution

Product Overview

The 36W Industrial Open Frame Power Supply is a compact, high-efficiency AC/DC converter engineered for seamless integration into professional-grade embedded systems and automated control environments. Delivering a precise 12V 3A output, this unit provides a stable, low-noise power foundation for ARM/X86 Industrial PCs, PLC Controllers, and IoT Edge Gateways that operate in space-constrained or high-temperature enclosures.

Featuring an ultra-compact standard footprint of 70 x 40 x 22 mm, this power supply maximizes spatial efficiency while maintaining superior thermal management. Recognizing that unique hardware designs often require specific mechanical constraints, we also offer Comprehensive Dimension Customization Services, allowing the PCB layout and profile to be tailored to your specific enclosure requirements.
