Product Details
15W to 1500W Single Output Industrial Power Supplies HWS-A Series
The TDK-Lambda HWS-A series of AC-DC power supplies, comprises five models rated from 15-150W. A significant upgrade of the established HWS series, which is still compatible with the new HWS-A series to enable easy upgrade. This switch mode power supply is up to 12% lighter compare to the previous series and features up to 91% efficiency and a very low power consumption at no load, contributing to a reduction in environmental impact. The HWS-A power supplies operate from a universal input of 85-265Vac, The 50, 100 and 150W models include active power factor correction, the operating temperature of the HWS-A models range from -10 to +50°C at full load and up to 70°C with appropriate derating. Typical industrial applications of these switch mode power supplies include equipment used for factory automation, process control, LED display and signage, test and measurement, broadcast and communications.
