UNSPSC 39121119: Motor-Alternator, 400 Hz

400 Hz alternators are especially designed for aviation Ground Power Units (GPU) that are driven by diesel engines to power aircraft while grounded for boarding and maintenance.

UNSPSC 39121119 Motor-Alternator, 400 Hz is a Commodity code that does not align with the recent state and local contract opportunities posted under this designation. The code's nominal scope—specialized electrical rotating machinery operating at 400 hertz—bears no meaningful connection to the actual procurements tagged with it, which span airport lighting systems testing, baggage handling operations, transit vehicle inspections, aquatic center operations, aircraft completions, engine procurement, drone equipment, bridge replacement, traffic signal installation, and airfield access control. The mismatch suggests either miscoding at the issuing body or a taxonomic misalignment between the UNSPSC framework and how state and local procurement offices are applying it in practice. Given this disconnect, the code shows no relevant recent activity for firms seeking to compete in 400 Hz motor-alternator supply or service delivery to state and local entities.

State and local governments do not currently appear to be buying motor-alternators at 400 hertz through open solicitation channels, at least not under this code designation. Pursue this code only if you have direct customer intelligence pointing to a specific procurement need outside the public notice record.
