Product Overview
Combine Charging and Auxiliary Power Conversion
The CTS3630-M04 integrates an on-board charger and a DC-DC converter within one fan-cooled assembly. The OBC provides high-voltage battery charging, while the DC-DC section provides 14V power for low-voltage electrical systems.
Circuit-board potting, independently mounted magnetic components and fully digital control form part of the product design. CAN communication, bootloader functionality and software parameter adjustment support commissioning and maintenance.
Select the high-voltage output range and auxiliary power rating that match your application.
Product Features
Designed for Vehicle Power Integration
Fully Digital Control
A modular power design with fully digital control supports the integrated charging and DC-DC functions.
