Li-Ion DC/DC Battery Charger Converters with E13 Approval, Galvanic Isolation, and 57V Output Voltage

Li-Ion DC/DC Battery Charger Converter with E13 Approval, Galvanic Isolation, and 57V Output Voltage

DC/DC converters are crucial in modern vehicle technology, serving as vital components for the efficient management of power supply across various electrical systems. Their role is especially important when charging Li-Ion batteries in vehicles, where stable and reliable power conversion can significantly influence performance and safety.

The DC Transformer 729-57-ON is specifically designed as a Li-Ion battery charger converter. The primary supply sources are the alternator with a 13.8V supply voltage or the car battery with a 12VDC voltage. Recently, our customer has started using a truck alternator with 27.6V and a D+ signal for activation. Due to its application, this DC/DC converter is automotive EMC-certified, making it an ideal choice for automotive applications due to its galvanic isolation.

DC/DC Converters with E13 Approval and Compliance with Standards

The E13 approval is a significant certification in the automotive industry, indicating that a product meets the European Union's standards for electromagnetic compatibility and safety. It signals that the DC/DC converter meets the high demands for automotive applications.

The DC/DC Battery Charger Converter 729-57-ON has been developed with a special focus on electromagnetic compatibility. It has been extensively tested for broadband electromagnetic interference and demonstrates that even the stringent limits in the range of 30MHz to 1GHz are significantly undercut.
