Overview
The VPP10-5600 is a 56 VA PC-mount power transformer from Triad Magnetics' World Series™ line, designed for through-hole PCB mounting in both domestic and international applications. It accepts a primary input of 115 V or 230 V at 50 or 60 Hz, and delivers a center-tapped secondary configurable as 10 V CT at 5.6 A (series) or 5 V at 11.2 A (parallel). This flexibility suits rectifier and linear power supply designs requiring low-voltage, higher-current outputs with a center tap reference.
The dual bobbin construction uses an insulating shroud - both made from high-temperature material that exceeds UL flammability requirements - providing very high isolation between primary and secondary windings and between each winding and the core. The dual bobbin construction effectively reduces capacitance, so electrostatic shielding is not required. The transformer is hi-pot tested at 4,000 VRMS, confirming robust dielectric isolation for designs where safety and regulatory compliance are critical. Compliance with CSA, IEC, TUV, and UL standards makes this unit suitable for products targeting multiple international markets without requiring a separate transformer variant.
The VPP10-5600 is dimensioned for precise through-hole PCB placement, with a mounting width of 2½ in and mounting depth of 2 in and overall dimensions of 3 in (W) x 2½ in (D) x 1 13/16 in (H). The unit weighs 1.70 lb. Designers should note that both primary and secondary coils may be connected as either series or parallel, but both coils must be used simultaneously - verify that the wiring configuration matches the target output voltage, current, and board layout requirements before finalizing the design.
