TRIAD MAGNETICS FS20120 Dual Primary Dual Secondary Transformer

The TRIAD MAGNETICS FS20-120 is a versatile power transformer featuring a dual primary and dual secondary split bobbin design. This configuration allows for operation with either a parallel input of 115V or a series input of 230V, providing flexibility in various applications. The transformer delivers output voltages of 20.0V with a center-tap under a 0.12A load when the secondaries are wired in series, or 10.0V under a 0.24A load when wired in parallel. The split bobbin construction eliminates the need for costly electrostatic shielding, making it a cost-effective solution for a wide range of industrial and commercial applications. It is UL Listed and RoHS compliant, ensuring safety and environmental responsibility.
