About this product
Victron Buck-Boost DC-DC Converter - 50 A regulates alternator-supplied DC power to charge a service battery despite changes in the supply voltage.
It is designed for 12 V or 24 V systems, including vehicles with smart alternators. Programmable settings, current limits and engine-running detection allow the charging arrangement to be matched to the vehicle and battery.
Key features
- Programmable buck/boost DC regulation
- Engine-running detection to help protect the starter battery
- Input and output current limiting
Configure the converter using the manufacturer's PC software. Maximum charging current depends on output voltage; do not assume the same current rating at both 12 V and 24 V.
