ZWS-C Series AC/DC Power Supplies

TDK-Lambda’s ZWS-C series of 10 W, 15 W, 30 W, and 50 W industrial AC/DC power supplies meet EN55011/EN55032-B conducted and radiated EMI in either a Class I or Class II (double insulated) construction. This is achieved without the need for additional 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 and measurement equipment.

Available output voltages are 5 V, 12 V, 15 V, 24 V, and 48 V (ZWS50-C model only). The ZWS10-C and the ZWS15-C models measure 63.5 mm x 45.7 mm x 22.1 mm (L x W x H), the ZWS30-C model measures 76.2 mm x 50.8 mm x 24.2 mm, and the ZWS50-C model measures 76.2 mm x 50.8 mm x 26.7 mm. The operating temperature with convection cooling and standard mounting is -10°C to +70°C, derating linearly to 50% load above +50°C to +70°C. With an external airflow of 0.8 m/s, the power supplies can operate full load at +70°C. No load power consumption is typically less than 0.3 W.

The power supplies have a 3 kV_AC input to output, 2 kV_AC input to ground, and 750 V_AC output to ground (Class I) isolation. All models are certified to the IEC/UL/CSA/EN62368-1 for AV, information, and communication equipment standard and EN60335-1 for household electrical equipment. In addition, IEC/EN61558-1 and IEC/EN61558-2-16 certifications have been obtained, simplifying system integration. The ZWS-C series also complies with IEC 61000-3-2 (harmonics), IEC 61000-4 (immunity), and carries the CE and UKCA marks for the low voltage, EMC, and RoHS directives. The warranty for the series is five years.
