Complies with EN 55011/EN 55022, FCC, and VCCI Class B. UL/CSA/EN 60950-1 and UL508 (with cover). Only products with the suffix A at the end of the part number are equipped with a cover; others have an open design. Power supplies, Series HWS-A, 15 to 1500 W, single output, industrial design. The AC/DC power supplies of the HWS-A series from TDK-Lambda are available in five models with 15–150 W. This represents a significant improvement over the proven HWS series, which is compatible with the new HWS-A series for easy upgrades. This switched-mode power supply is up to 12% lighter compared to the previous series and features up to 91% efficiency, along with a very low power consumption in no-load operation as part of reducing environmental impact. The HWS-A power supplies operate via a universal input of 85–265 V ac. The 50, 100, and 150 W models include active power factor correction, and the operating temperature of the HWS-A models ranges from -10 to +50 °C at full load, with a corresponding power reduction allowing operation up to 70 °C. Typical industrial applications for these switch-mode power supplies include factory automation systems, process control, LED displays and signage, testing and measurement, broadcasting, and communication. High efficiency up to 91%, wide AC input range, cost-effective, easy system cooling, supports global use, limited lifetime warranty.
