## Long description

Weldman Inventor Smart 100 is a rectifier designed for charging and supporting 12V and 24V electrical systems. It delivers regulated DC output for battery charging and includes a start (boost) function to assist with engine starting. The unit is intended for use with cars, light trucks, agricultural machinery and construction equipment that accept 12V or 24V charging and starting support.
Advantages
The rectifier offers dual-voltage compatibility, enabling a single device to serve both 12V and 24V systems. Built-in regulation provides stable DC charging to reduce overcharging risks and support battery maintenance. The integrated start function supplies additional current for jump-starting engines without requiring a separate starter battery. Compact design and straightforward controls simplify installation and daily use.
