ADH200120 is a PCB-mounted power transformer rated at 1.1VA with dual 115/230V primary windings (±10% @ 50/60Hz) and dual secondary windings that can be configured for either series or parallel connection. The transformer features a maximum temperature rise of 45°C, excitation current of 25mA maximum, and high-pot insulation ratings of 2500Vrms (primary to secondary) and 1500Vrms (primary/secondary to core) for 1 minute. In series connection, it delivers 120V output at 9.2mA, while in parallel connection it provides 60V at 18.3mA, making it suitable for various low-voltage AC applications. The device is constructed with Class B insulation system (ZM-130-5) and meets UL506 safety standards for general-purpose transformers in US and Canada markets.
