The TDK Corporation ZWX240 is a versatile open-frame AC/DC converter designed for industrial applications. It delivers up to 120W of power under natural convection and 204W with forced air cooling, with a peak power capability of 180W.
This unit features a universal input voltage range of 85-265 VAC and a frequency range of 47-63 Hz. It provides multiple outputs including +3.3V, +5V, +12V, and -12V, with specific current ratings for each under different cooling conditions. The converter boasts an efficiency of up to 84% and includes features such as Power Factor Correction (PFC), remote on/off, and remote sensing.
Designed for chassis mounting, the ZWX240 has dimensions of 225.0mm x 106.0mm x 35.0mm. It operates within a wide ambient temperature range of -10°C to 70°C with derating. Safety certifications include UL60950-1, CSA60950-1, EN60950-1, and EN50178, along with compliance to harmonic input current regulations and noise standards.
Key electrical specifications include a typical power factor of 0.99 at 100VAC, surge current up to 28A, and leakage current below 0.75mA. It also offers overcurrent and overvoltage protection, with remote sensing available on the V1 output.
