ADH30010 is a PCB-mounted power transformer with dual 115/230V primaries and dual secondaries, delivering a maximum power of 2.4VA. The transformer operates at input voltages of 115/230V ± 10% at 50/60Hz frequency, with secondary output options of 5V at 500mA (parallel connection) or 10V at 250mA (series connection). It features a maximum temperature rise of 45°C, excitation current of 25mA maximum, and high-pot ratings of 2500Vrms (primary to secondary) and 1500Vrms (primary/secondary to core) for 1 minute, meeting UL506 General Purpose safety standards with Class B insulation system. The dual-configuration design allows flexible voltage and current output selection, making it suitable for industrial control systems, power supplies, and general-purpose electronic equipment requiring compact PCB integration.
