PMS9505 Series High Isolation Current Sense Transformer

The PMS9505 series from Pulse Electronics, a YAGEO Company, has a unique construction. The primary winding is molded into the plastic base forming a solid insulation barrier for achieving reinforced insulation properties per IEC60664/IEC60950-1 for a working voltage of up to 300 VRMS. The PMS9505 has current sensing from the low DCR primary, allowing for a rated current of 30 ARMS with a range of turn ratios from 1:50 to 1:180. Many automotive applications require reinforced insulation, where current needs to be measured across different ground planes. This is a typical requirement for onboard chargers (OBC) and DC-to-DC converters in electric vehicles (EV). PMS9505 is designed to satisfy these requirements.
