Overview
The Triad VPS16-5000 is a chassis mount, quick-connect World Series™ power transformer rated at 80 VA. It accepts a primary input of 115 V or 230 V at 50 Hz or 60 Hz, making it suitable for both domestic and international applications. The secondary winding is configurable: wired in series it delivers 16.0 V CT at 5.0 A, and wired in parallel it delivers 8.0 V at 10.0 A, supporting a range of low-voltage power supply designs including center-tapped full-wave rectifier circuits.
The dual bobbin construction positions the primary and secondary coils inside an insulating shroud built from UL-approved high-temperature material. This configuration results in minimal inter-winding capacitance, eliminating the need for electrostatic shielding. Both the primary and secondary coils are electrically isolated from each other and from the core. The transformer has been hi-pot tested at 4,000 VRMS, confirming robust dielectric integrity for safety-critical designs. Compliance with CSA, IEC, TUV, and UL requirements supports use in equipment destined for multiple international markets.
The Triad VPS16-5000 is designed for chassis mounting, with a mounting footprint of 2 in x 2¼ in and 13/64 x 3/8 in mounting holes, and an overall envelope of 3 in (H) x 2½ in (W) x 2 5/16 in (D). Connections are made via quick-connect terminations. Designers should note that both primary and secondary coils may be connected in either series or parallel configuration, but both windings must be used simultaneously. Verify that the chosen winding configuration, output voltage, and current rating match the intended load requirements.
