... Remote sense Description The Bel SRDB-07A modules are a series of non-isolated, step down DC/DC power converters that operate from a nominal 12V source. These converters are available in a range of output voltages from 1.2V to 5.0V. They are packaged in a compact, low profile, surface mount DIP package for ease of layout and space savings. 7A maximum output is also provided. Standard features include remote on/off, over current and short circuit protection, UVLO and output voltage adjust ...
