Automotive Transformers with Isolation of 3000Vac or 4000Vac

Mornsun launched the company’s automotive, isolated transformer series – TTLS03-15B-T, TTLDE05-20B-D, and TTLHE10 20 25 -D. These series of flyback transformers have an isolation voltage of 3000Vac and 4000Vac. In addition to meeting AEC-Q200 standards, they feature compact size and are cost-effective. Their operating ambient temperature range is -40℃ to +110℃.

The ac-dc transformers can be widely utilized in consumer electronics and industrial applications. (See typical application diagram of TTLDE05-20B-D above)  According to Mornsun, they offer a wide input voltage range and provide various protection functions and deliver superior EMI performance.

The TTLS03-15B-T series of ac-dc transformers operate in flyback mode (SCM1702A). This series has an input voltage range of 85Vac to 305Vac.  They have an output power of ≤3W. It features and EPC13 bobbin. The TTLS03-15B-T series meets UL/EN 62368 standards in addition to meeting AEC-Q200.

Mornsun’s new TTLDE05-20B-D series also operates in flyback mode  (in this case SCM1703A). This series has an input range of 85Vac to 264Vac and output power of ≤5W. It features an EE10 bobbin, and it meets both AEC-Q200 and UL/EN 62368 standards.

The company’s TTLHE10/20/25-20B-D Series operates in flyback (in this case SCM1710A). Input voltage ranges from 85Vac to 264Vac and output power is from 10W to 25W. This ac-dc transformer series has either an EFD15, EFD20, or EFD25 Bobbin. Equipped with a shielding layer, the device boasts superior EMI performance. It meets UL/EN 62368 and AEC-Q200 standards.
