Industrial power supply series expanded with new mounting and protection options

TDK Corporation has introduced multiple option configurations for the TDK-Lambda brand ZWS-C series of 10W, 15W, 30W, and 50W-rated industrial AC/DC power supplies. Originally launched in an open frame configuration, four extra options are now available in the series: a metal L-bracket (with or without a cover), pins for PCB mounting, and two-sided board coating for all voltage and power levels. These options can provide further operator protection, lower the cost of wiring harnesses, or lessen the impact of dust and contamination in harsh environments.

With electrolytic capacitor lifetimes of up to 15 years, the models can be employed in factory automation, robotics, semiconductor fabrication manufacturing, and test and measurement equipment.

The series is available with 5V, 12V, 15V, 24V, and 48V (50W only) output voltages. The ZWS10C and ZWS15C models measure 63.5mm x 45.7mm x 22.1mm (L x W x H), the ZWS30C 76.2mm x 50.8mm x 24.2mm, and the ZWS50C 76.2mm x 50.8mm x 26.7mm. The operating temperature with convection cooling and standard mounting ranges from -10C to 70C, derating linearly to 50% load between 50C to 70C. 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. The models meet EN55011/EN55032-B conducted and radiated EMI in either a Class I or Class II (double insulated) construction without external filtering or shielding.

All models are also certified to the IEC/UL/CSA/EN62368-1 for AV, information and communication equipment standards and EN60335-1 for household electrical equipment. Also, 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) and 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.
