UNSPSC 32101533: Output transformer

A transformer that is connected to the output of the amplification circuit that uses the transistor or electronic tube and others to change the impedance of external load circuit to the optimum load impedance for transistor or electron tube load.

UNSPSC 32101533 Output transformer is a Commodity code capturing a narrow range of specialized electrical and communications equipment that state and local governments procure for emergency responder systems, public safety infrastructure, and research facilities. Recent solicitations show state and local buyers using this code to source in-building radio frequency coverage enhancement systems (including bi-directional amplifiers and distributed antenna systems), emergency responder communication enhancement systems (ERCES) for inspection and compliance, radiofrequency shielded chambers for engineering research, and ruggerized cellular routers for critical operational technology systems. Issuing bodies span city procurement offices (City of Phoenix Finance Central Procurement), county water and emergency services departments (Hillsborough County Water Resources, Santa Clara County Sheriff), school districts (Rockwood School District R-VI in Missouri, Polk County School Board in Florida), state universities (University of Wisconsin-Madison), and state-level cooperative purchasing vehicles (Sourcewell on behalf of Minnesota and Washington jurisdictions and participating entities nationwide). The City of Phoenix has posted two separate ERRCS solicitations within the recent window, indicating repeat buying activity in that jurisdiction.

Geographic activity concentrates in Arizona (City of Phoenix), Florida (Polk County School Board, State of Florida RFI), Missouri (Rockwood School District), California (Santa Clara County), and Wisconsin (University of Wisconsin-Madison), with secondary activity across Washington and Minnesota through the Sourcewell cooperative procurement framework. Representative recent opportunities include the City of Phoenix Finance Central Procurement's IFB-26-0355 for in-building radio frequency coverage revision with a July 10, 2026 response date and five-year contract term commencing August 25, 2026, requiring turnkey ERRCS design, installation, and testing with NFPA 1225 and UL 2524 compliance; Rockwood School District R-VI's RFP 26-14203 for approximately 150 digital bus radios and repeater equipment with DMR Tier 2 and ultranarrowband compliance, due April 29, 2026, and contract commencement July 1, 2026; the Polk County School Board's ITB for ERCES semi-annual and annual inspections with NFPA 1225 compliance, due March 12, 2026; and the University of Wisconsin-Madison's RFB for RF shielded engineering chambers, due February 12, 2026, through the ShopUW+ portal. Sourcewell's RFP #061626 for law enforcement equipment represents a multi-state cooperative contracting vehicle with participation from counties in Washington and other jurisdictions nationwide, due June 16, 2026.
