Soldick TSD-3S is a 300 VA single-phase transformer with dual windings, featuring selectable primary taps at 200, 220, and 240 VAC and secondary taps at 100, 110, and 115 VAC. The secondary winding is rated for 3 A, and the unit is specified for 50/60 Hz operation. It steps down 200–240 V mains to 100/110/115 V outputs for equipment that requires those voltages from a standard mains supply.
