Filament Power Transformers with Low Voltage

Hammond Manufacturing Filament Power Transformers with Low Voltage include a variety of chassis-mount modules with an open or enclosed style. These transformers feature a dual bobbin design with no electrostatic shield required and 6" (minimum) long leads. The 165 Series and 265 Series also are available with copper tabs with holes. Hammond Manufacturing Filament Power Transformers with Low Voltage feature an overall volt-amps (VA) power rating ranging from 0.63VA to 640VA. The 165 Series, 166 Series, and 167 Series offer a 115V primary voltage rating, while the 265 Series and 266 Series have a 117V/234V primary voltage rating. All of these transformers are UL listed and CSA certified.
