Bourns high clearance/creepage distance isolation power transformer

Bourns magnetics product line is pleased to introduce the new model HCTSM100308BAL high clearance/creepage distance isolation power transformer. This high voltage isolation transformer is driven from 3.3VDC to 5VDC input, delivers from 8VDC to 12VDC, up to 125mA output and, if required, can be configured in a variety of turns ratios.

The model HCTSM100308BAL is 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 any application that requires isolation from potentially hazardous voltages (e.g., from a high voltage battery in a 1000 V battery pack or energy storage system).

This power transformer offers a working voltage of up to 1000V_rms and Hi-Pot isolation voltage up to 4000VDC, with an extended operating temperature range from -40°C to +125°C.

The model HCTSM100308BAL is built with a ferrite toroid core for a high coupling factor and efficiency. The reinforced isolation, 10mm min. clearance/creepage distance, and 4kV at 60 second withstanding voltage provide an elevated degree of isolation from high voltage hazards. The transformer is designed for isolation power supplies using Texas Instruments’ Model SN6501 and SN6505B, and is compliant with IEC/UL 60950-1 and IEC/UL 62368-1 requirements.
