RECOM Power R-78W-0.5 Wired Single Output DC/DC Converters

RECOM Power R-78W-0.5 Single Output DC/DC Converters are wired 0.5A switching regulators ideally suited to offer a stable voltage supply without the need for a PCB. High efficiencies of up to 96% mean there is no need for a heat sink. The compact modules feature fully protected outputs and draw only 1mA under no-load conditions. These converters are ideal for use in applications such as high-power LED lighting, battery-powered systems, cooling systems, or fans.
