CBS504812 Description

Short technical summary and product information.

The Cosel CBS504812 is a 50W isolated DC-DC converter from the CBS series, designed for telecommunications and industrial applications. It accepts a wide input voltage range of 36-76V DC and provides a regulated 12V output at up to 4.2A.

 

Key electrical characteristics include a typical efficiency of 88% at nominal input and full load, line regulation of 24mV max, load regulation of 24mV max, and ripple and noise of 150mVp-p max over the -20 to +100°C temperature range. The converter also features overcurrent protection (105% of rating, auto recovery), overvoltage protection (13.80-16.80V), and remote on/off with negative logic.

 

The CBS504812 is packaged in a half brick (61.0mm x 57.9mm x 12.7mm) with through-hole mounting and M3 tapped mounting holes. Operating temperature range is -40°C to +100°C with derating. Safety agency approvals include UL60950-1, C-UL, and TUV.
