Product Specifications
Review the technical data used for replacement matching, procurement comparison and engineering approval.
Historical listing view - supplied unit verification required
The retained complete angled rear shows the model, separate -5W33 and printed input. Visible red, black, blue and yellow leads, pale multiposition housing and jumper loop do not establish contact functions or current supplied pinout. These are existing historical listing photographs, not confirmation of the unit currently offered for shipment, its condition or an unedited camera original.
The historical label records Delta EFC1248DF; separate -5W33 and DC48V 0.33A. Match the full supplied marking, dimensions, condition, actual leads, connector keying and pinout before ordering. Existing dimensions, bearing and performance specifications remain listing or catalogue references requiring supplied-option verification.
Retained historical rear-label view; archived historical alternative full photograph. Alternative watermarked images remain in store records outside this gallery.
