Industrial ETV251 Power Supply

The Emerson/ACDC Electronics ETV251 power supply is a compact dual-output DC source designed for industrial equipment. It provides two fixed rails: 5V DC at up to 2A and 12V DC at up to 0.4A, enabling a single module to power both logic-level circuitry and peripheral devices without requiring separate supplies. Identified by model number ETV251, this unit is associated with ACDC Electronics and has historical branding connections to Emerson/Astec Power lineage. The module is listed as discontinued by the manufacturer, so current availability comes from surplus catalogs or secondary distributors rather than new production. The dual-output design helps reduce wiring complexity and cabinet footprint in control panels where both 5V and 12V rails are needed from one enclosure-mounted unit. When sourcing this model, verify that the provenance matches authentic ETV251 components and confirm the input requirements, connector interfaces, and physical form factor with the seller, since exact compatibility depends on the vintage equipment and the specific ETV251 family variant you are replacing. This model is most applicable in older automation or instrumentation setups that called for a combined supply of 5V and 12V rails from a single, dedicated unit, making the ETV251 a recognizable option for legacy systems seeking a two-rail DC solution.
