Overview

The HWS150A-12 is an enclosed 150 W AC-DC power module from TDK-Lambda that provides a single 12 V output at up to 13 A. It accepts a wide input range (85-264 VAC or 120-370 VDC), offers 3 kV isolation, and is specified for industrial and ITE applications. Typical efficiency is about 86% and the unit requires thermal derating above ambient temperatures noted in the datasheet.

Why Choose This Part

Choose the HWS150A-12 when you need a compact, enclosed 150 W 12 V source with wide universal AC input and support for high DC input voltages. Its 3 kV isolation rating and industrial operating range make it suitable for demanding environments, while roughly 86% efficiency helps reduce heat load in enclosed cabinets. The enclosed form factor simplifies mechanical integration and protection compared with open-frame alternatives.

Applications

Industrial control cabinets
Reliable 12 V supply for PLCs, I/O modules, motor controllers, and fieldbus gateways in factory automation.
Embedded and edge computing
Power single-board computers, industrial controllers, and on-premise network appliances that need a rugged enclosed supply.
Instrumentation and test equipment (ITE)
Supply bench-top or rack-mounted instrumentation and commercial test systems requiring isolated 12 V rails.
Machine vision and cameras
Deliver stable 12 V power to industrial cameras, lighting controllers, and image-processing hardware.
Signage and compact LED systems
Drive 12 V LED arrays and signage where a robust enclosed supply and good efficiency are required.

Getting Started

Review the TDK-Lambda datasheet for the unit's derating curve, recommended mounting orientation, and wiring details. Use appropriate wire gauge and fusing for a 13 A output, allow ventilation or forced airflow if your installation approaches high ambient temperatures, and follow isolation and grounding practices for industrial/ITE systems. No development tools are required for a power module, but validate installation with a multimeter and appropriate load during commissioning.
