50W to 600W Single Output Industrial Power Supplies RWS Series
The TDK-Lambda RWS-B series of AC-DC power supplies comprises four models rated from 50 to 600 watts, featuring simple function design, compact dimensions, and high efficiency. The RWS-B series of switch mode power supplies is positioned as a mid-range product with simple functionality. The RWS-B series come in a simplified, compact, highly efficient power supply package. Improved efficiency at low loads and power consumption during stand-by contribute to reduce the environmental impact. The RWS-B power supplies offer outstanding thermal performance for cooler operation over their operating temperature range of -10 to +70°C; the RWS100B and RWS150B models are convection cooled, whereas the higher power models incorporate an internal cooling fan. These enclosed AC-DC power supplies operate from a universal input of 85-265Vac to meet a wide range of applications, including industrial, test & measurements, broadcast, communication and LED signage.
