Supplies feature low output noise, long field life

TDK has announced the ZWS-C series of 10, 15, 30 and 50W rated industrial AC/DC power supplies. The products meet EN55011/EN55032-B conducted and radiated EMI in either a Class I or Class II (double insulated) construction, without the need for external filtering or shielding. With electrolytic capacitor lifetimes of up to 15 years, the ZWS-C can be used in factory automation, robotics, semiconductor fabrication manufacturing and test/ measurement equipment.

Available output voltages are 5, 12, 15, 24V, plus 48V for the ZWS50-C model only. Operating temperature with convection cooling and standard mounting is -10 to 70°C derating linearly to 50 per cent load above 50 to 70°C. With an external airflow of 0.8m/s, the power supplies can operate at full load. No load power consumption is typically less than 0.3W.

The power supplies have a 3kVAC input to output, 2kVAC input to ground and 750VAC output to ground (Class I) isolation.
