The ZWS50BAF-12 is a 50W open frame AC/DC power supply designed by TDK Corporation for industrial and commercial applications. It accepts a wide universal input voltage range of 85 to 265 VAC, making it suitable for global deployment without regional modifications. The unit provides a regulated 12V DC output capable of delivering up to 4.3A of continuous current.
Engineered for efficiency and reliability, this converter achieves an efficiency rating of 85% while incorporating active Power Factor Correction (PFC). It supports series operation and load sharing, allowing system designers to scale power delivery for higher wattage requirements. The design includes comprehensive protection features such as over-current protection with hiccup mode recovery and over-voltage protection requiring manual reset.
Mechanically, the ZWS50BAF-12 utilizes a robust chassis mount configuration with dimensions of 50mm x 26mm x 132mm. It operates reliably within a temperature range of -10°C to +70°C using convection cooling. Electrical isolation is rated at 3kVAC between input and output, ensuring safety in demanding environments. The unit meets stringent emission standards including EN55011, EN55032-B, FCC-B, and VCCI-B, alongside safety approvals like UL62368-1 and EN62368-1.
