Figure 1. Block diagram of BR15

BR15 has protection against overvoltages of more than 33 V, protection against polarity reversal, and protection against short-circuits on the output.

BR15 provides stabilized output voltage and galvanic isolation between input and output. The unit operates in “step up” and “step down” modes, depending on the input voltage supply, and provides a stabilized 14.5 ± 0.5 VDC output.
