Bourns launches 2nd-gen automotive isolation transformers
Summary
By providing a separate reinforced insulating layer that protects against dangerous voltages, the Model HCT8xxxEAL Series helps designers better meet their safety and reliability goals compared to competitive isolation transformers that are only capable of functional insulation. The advanced features in this series make these transformers ideal for use in isolation applications in automotive Battery Management Systems (BMS), RS-485, CAN interface, digital input module, and RS-323 isolation designs. Bourns’ latest high voltage isolation transformers feature 3.3 or 5V input to various output voltages per turn (up to 350mA in various turns ratio configurations). Manufactured in a fully automated line that maximises device quality and reliability, the Model HCT8xxxxxEAL Series is designed with Bourns’ over-moulding technology that uses cost-effective FIW wire to deliver superior efficiency. In addition to the reinforced isolation with 8mm minimum clearance/creepage distance that delivers an elevated level of isolation from high voltage hazards, this series is compliant with IEC 62368-1 and IEC 61558-1 standards.
