Overview
The VPL16-300 is a 5 VA chassis mount leaded power transformer from Triad's World Series™ line, designed for dual-mains compatibility at 115 V and 230 V on 50/60 Hz systems. The secondary winding supports two configurable output options: 16.0 V at 0.310 A with center tap in series, or 8.00 V at 0.620 A with center tap in parallel. This flexibility suits low-power applications requiring either a higher-voltage/lower-current or lower-voltage/higher-current supply from a single transformer, with the center tap enabling half-wave or full-wave rectified configurations.
The VPL16-300 uses European style split bobbin construction, which reduces interwinding capacitance and eliminates the need for a separate electrostatic shield. The transformer provides 3,500 V isolation between primary and secondary and a 6 mm creepage distance, meeting international safety agency standards. This makes it well suited for equipment intended for global markets where both IEC and North American mains voltages may be encountered. Safety compliance covers UL (File E65390) Class 2/3 and TUV recognitions.
The VPL16-300 is a chassis mount, leaded component measuring 1 7/16 in (H) x 2 3/8 in (W) x 1 7/16 in (D) with a 2 in mounting width and a weight of 0.40 lb. Designers should note that primary and secondary windings are designed to be connected in series or parallel and are not intended to be used independently. Verify that the required output voltage, current, and winding configuration align with the series or parallel connection options provided, and confirm chassis cutout and mounting hole dimensions against the stated case type and mounting width.
