6495-028 Laminated Power Transformer Equivalent & Substitute Parts

Part Overview

The 6495-028 is a 43VA laminated core power transformer manufactured by API Delevan Inc., designed for chassis mount applications with dual primary and secondary windings. The device supports selectable voltage configurations (115V or 230V primary input) and dual secondary output modes (14V parallel or 28V series), delivering maximum output currents of 3A in parallel mode or 1.5A in series mode.

The 6495-028 carries an obsolete product status, making it necessary to identify active equivalent components for new designs, repairs, and long-term supply chain planning. Obsolete status indicates the manufacturer no longer produces this part, and existing inventory will eventually deplete.
