Power-One HAD12-.4-A DC-DC Converter Module Power Supply

Power-One HAD12-.4-A DC-DC Converter Module Power Supply is a compact, pluggable power conversion module from Power-One designed for integration into electronic systems. The HAD12-.4-A designation identifies the exact module variant, helping engineers confirm compatibility within a system’s power architecture and BOM. As a DC-DC converter module, it sits in a power distribution chain inside a chassis or enclosure, converting input DC power to the DC rails used by downstream circuitry. This modular form factor supports flexible power provisioning in equipment where a dedicated Power-One module is preferred for supplying regulated DC power to individual boards or subassemblies. The HAD12-.4-A variant belongs to Power-One’s family of power solutions, offering a standardized module approach that aligns with common practices in industrial control, instrumentation, and telecom environments where reliable, compact DC power conversion is needed.
