The TDK ZWX300 is a chassis-mount, open-frame AC-DC converter providing five regulated outputs: +3.3V, +5V, +12V, -12V, and +5V standby. It accepts a universal input of 85-265VAC at 47-63Hz and delivers a total output power of 90W under natural convection and 153W with forced air cooling (0.85 m³/min). Peak output power is rated at 180W.
Electrical specifications include a typical efficiency of 81% at 100VAC and 84% at 200VAC, a power factor of 0.99/0.93, and a hold time of 20ms at 100VAC. The converter features overcurrent protection on all outputs, overvoltage protection on V1, V2, and V3, remote sensing on V1, and a TTL-compatible remote ON/OFF (PS_ON) input compliant with the ATX standard. Output voltage set accuracy is ±5%.
The ZWX300 operates over a -10°C to +70°C temperature range with derating: 100% load up to 50°C, 60% load at 60°C, and 20% load at 70°C. It is designed for natural convection or forced air cooling. The unit measures 94 x 36 x 210 mm and weighs 500g. Safety certifications include UL60950-1, CSA60950-1, EN60950-1, EN50178 (OV II), and PSE (for 100VAC only). It also complies with harmonic current emissions (IEC61000-3-2), conducted and radiated noise standards (EN55011/EN55022-B, FCC-ClassB, VCCI-B), and immunity standards (IEC61000-4-2, -3, -4, -5, -6, -8, -11).
The ZWX300 accepts an input voltage range of 85 to 265 VAC at 47 to 63 Hz.
The ZWX300 provides +3.3V (6A), +5V (5A), +12V (6A), -12V (0.2A), and +5V standby (1.4A) under natural convection. With forced air cooling, currents increase to 8.4A, 7A, 9A, 0.3A, and 2A respectively.
The ZWX300 delivers 90W total output power with natural convection and 153W with forced air cooling. Peak output power is 180W.
The ZWX300 operates from -10°C to +70°C with derating: 100% load up to 50°C, 60% load at 60°C, and 20% load at 70°C.
Yes, the ZWX300 has a TTL-compatible remote ON/OFF (PS_ON) input that is compliant with the ATX standard. High signal disables output, low signal enables output.
The ZWX300 is certified to UL60950-1, CSA60950-1, EN60950-1, and EN50178 (OV II). It also complies with the Japanese Electrical Appliance and Material Safety Law (PSE) for 100VAC operation.
The ZWX300 measures 94 x 36 x 210 mm (W x H x D) and weighs 500g.
