Our RLPB15 Series of regulated 4:1 wide input range 15-watt single- and dual-output DC-DC converters come in a miniature 1.0” x 1.0” x 0.39” package to fit space constraints in railway applications. This series features high efficiency up to 91%, low standby power, high reliability power, and remote ON/OFF control for energy savings. Built-in safeguards include over current, over voltage, short circuit and under voltage protections. These converters also provide an internal EN55032 Class A filter, and a six-sided continuous shield minimizes noise leakage. The converters meet EN50155 and EN45545-2 Railway Standards as well as UL60950-1, EN60950-1, IEC60950-1, UL62368-1, EN62368-1 and IEC62368-1. This RLPB series of products comply to RoHS, REACH and carry the CE Mark.
