Advantech BB-SD-50 Series

Power all your devices – no matter what the voltage. Many applications have devices that use different voltages. Mean Well DC-DC converters deliver the correct voltages to power other DC devices with differing voltage requirements. Mean Well converters are used in nearly every industry requiring low-to-medium DC-to-DC voltage conversion in the 15-1000 Watt range.
