ADH30012 is a 2.4VA power transformer designed for PCB mounting with dual 115/230V primary windings and dual secondary windings that can be configured in series or parallel. The transformer operates at input voltages of 115/230V ±10% at 50/60Hz frequency, with secondary output options of 6.3V at 400mA (parallel connection) or 12.6V at 200mA (series connection). It features a maximum temperature rise of 45°C, excitation current of 25mA maximum, and meets UL506 safety standards with Class B insulation system rated for 130°C. The high-pot ratings of 2500Vrms (primary to secondary) and 1500Vrms (primary/secondary to core) ensure robust electrical isolation. This transformer is ideal for general-purpose power supply applications, industrial control systems, and consumer electronics requiring reliable step-down voltage conversion with flexible output configurations.
