vepac-la1644-group-with-coverTDK Corporation announces the introduction of the TDK-Lambda HWS-A series of AC-DC power supplies, which comprises five models rated from 15-150 W to meet a wide range of customer requirements. A significant upgrade of the established HWS series which was originally introduced in 2005, typical industrial applications include equipment used for factory automation, process control, LED display and signage, test and measurement, broadcast and communications. The HWS-A is completely form, fit and function compatible with the HWS series to enable easy upgrade, with the added bonus that it is up to 12% lighter in weight. The new series also achieves up to a 3% improvement in efficiency at full load (up to 91% efficiency), and up to a 4% improvement at low loads. Power consumption at no load is also considerably lower, thereby contributing to a reduction in environmental impact. Operating from a universal input of 85-265 V AC (47-63 Hz), the 50, 100 and 150 W HWS-A models include active power factor correction and all models are EN61000-3-2 compliant. HWS-A meets SEMI F47 requirements at high line input.
