The ZWS50BAF-3/A is an enclosed AC/DC converter manufactured by TDK Corporation, part of the ZWS series. It delivers a single output of 3.3V DC with a maximum current of 10A and total power of 50W. The converter accepts a universal input voltage range of 85-265VAC (47-63Hz) or 120-370VDC, making it suitable for global applications. Typical efficiency is 78%, and it includes built-in power factor correction (PFC) to meet IEC61000-3-2 harmonics standards.
Electrical protections include overcurrent protection (minimum 10.5A) and overvoltage protection (3.79-4.95V). Ripple and noise are limited to 120mV max at typical operating temperatures (0-70°C) and 160mV max at low temperatures (-10-0°C). Line and load regulation are within 20mV and 40mV respectively. Hold-up time is 20ms typical. The converter features 3kVAC input-to-output isolation, 2kVAC input-to-FG, and 500VAC output-to-FG isolation.
Mechanically, it is designed for chassis mounting in an enclosed form factor. Dimensions are 50 x 26 x 132 mm and it weighs 165g typical. Cooling is by natural convection, and the operating temperature range is -10°C to +70°C with derating above 50°C (75% load at 60°C, 50% at 70°C). Storage temperature range is -30°C to +75°C. The unit is suitable for ITE (commercial) applications and carries CE approval.
The input voltage range is 85-265VAC (47-63Hz) or 120-370VDC.
Output voltage is 3.3V nominal (range 2.97-3.63V) with maximum output current of 10A and maximum power of 50W.
The operating temperature range is -10°C to +70°C with derating above 50°C (100% at ≤50°C, 75% at 60°C, 50% at 70°C).
