The TDK Corporation ZWS100BAF-3/A is an enclosed AC/DC power supply designed for ITE (Commercial) applications. It provides a nominal output voltage of 3.3V and a maximum output current of 20A, resulting in a maximum output power of 100W.
The converter operates with a wide input voltage range of 85-265VAC and features convection cooling. It is designed for chassis mounting and includes features such as adjustable output, DC input capability, load sharing, and Power Factor Correction (PFC).
Key electrical specifications include an efficiency of 84%, a typical input current of 0.45A at 100VAC, and an inrush current of 14A at 100VAC. The operating temperature range is -10°C to 70°C with derating, and storage conditions range from -30°C to +75°C.
Compliance includes CE approval, with designed-to-meet standards for conducted and radiated emissions (EN55011/EN55032-B, FCC-B, VCCI-B) and EMC (IEC61000-6-2). It also meets various safety standards like UL62368-1 and EN62368-1.
The input voltage range is 85-265VAC (47-63Hz) or 120-370VDC.
The output voltage is 3.3V with a maximum output current of 20A, providing up to 100W.
The operating temperature range is -10°C to 70°C with derating (100% load at -10°C to 50°C, 75% at 60°C, 50% at 70°C).
It uses convection cooling, requiring no external fan.
Isolation is 3kVAC between input and output, 2kVAC between input and FG, and 500VAC between output and FG.
The typical efficiency is 84%.
The dimensions are 50 x 26 x 132 mm and the typical weight is 165g.
