CUI Inc PRQExW-D 50W/75W Isolated DC-DC Converters
CUI Inc PRQExW-D 50W and 75W Isolated DC-DC Converters offer 3kVDC isolation and an ultra-wide 9V to 75V input range in a 1/4 brick package with industry-standard pin-out. The single regulated output PRQE50W-D and PRQE75W-D devices provide output short-circuit, over-current, over-voltage, and over-temperature protection. Operating within a -40°C to +105°C temperature range, these DC-DC converters feature a 90% typical efficiency with 12VDC, 15VDC, 24VDC, 28VDC, and 48VDC outputs. Applications include railway, renewable energy, and industrial applications where a large amount of power is needed in a compact package.
