High Voltage, High Clearance/Creepage Distance Isolation Power Transformers

Bourns Magnetics Product Line’s high voltage, high clearance/creepage distance isolation power transformers are driven by 3.3 V to 5 V input, deliver 3.3 V to 15 V up to 350 mA output, and can be configured in a variety of turns ratios. The transformers are built with a ferrite toroid core for a high coupling factor and efficiency. They are designed to support isolated interface power for CAN, RS-485, RS-422, RS-232, SPI, I²C, and lower power LANs in a range of applications such as industry 4.0 and applications that require isolation from potentially hazardous voltages (e.g., from a high voltage battery especially inside a 1500 V energy storage system).

Both transformers are designed for isolation power supplies using Texas Instruments models SN6501 and SN6505B transformer drivers or similar push-pull drivers from other manufacturers. The model HCTSM100304FL is compliant with IEC 60664-1 and IEC 62368-1 standards, and the model HCTSM150102HL is compliant with IEC 60950-1 and IEC 62368-1 standards.
