The ZWX240/A2 is an AC/DC converter from TDK Corporation designed for systems requiring multiple output voltages. It accepts a universal input of 85-265 VAC at 47-63 Hz and delivers five outputs: +3.3V, +5V, +12V, -12V, and +5VSB. Total output power is 90W under natural convection cooling, 153W with forced air, and up to 180W peak. Typical efficiency reaches 81% at 100VAC and 84% at 200VAC.
The converter includes overcurrent protection on each output and overvoltage protection on V1, V2, and V3. Remote sensing is available on V1. Output regulation is within ±5% voltage set accuracy. Ripple and noise are typically 120-160 mVp-p depending on temperature range.
Operating temperature range is -10 to 70°C with derating: full load at 50°C, 60% load at 60°C, and 20% load at 70°C. Storage temperature is -30 to 85°C. The unit supports natural convection or forced air cooling for flexible thermal management. Hold-up time is 20 ms at 100VAC.
