The TDK ZWS240PAF-48 is a single-output AC/DC converter that provides 48V DC at 5A, delivering 240W of continuous power. It accepts a universal AC input of 85-265 VAC (47-63Hz) or DC input of 120-370VDC, making it suitable for worldwide applications. Typical efficiency is 82% with power factor correction (0.99 at 100VAC), meeting EN61000-3-2 harmonic standards.
The converter features overcurrent protection (>102% of peak current capability) and overvoltage protection (55.2-64.8V on 48V output). Line regulation is 0.4% and load regulation 0.8%, with ripple and noise at 1%. The unit is designed for convection or forced-air cooling (1.5m/s) and operates from -10°C to +70°C (open frame) with derating above 60°C.
Mechanical dimensions are 222.0mm (L) x 95.0mm (W) x 42.0mm (H). Weight is 500g typical for open-frame version, 800g with cover. Safety certifications include UL60950-1, CSA60950-1, EN60950-1, EN50178, and CE marking. Conducted and radiated EMI meets EN55022-B, FCC Class B, and VCCI-B standards.
