Equipped with advanced production lines and testing equipment, GA&DA ensures every protection device meets international safety standards.
Our team follows ISO9001 processes from R&D to delivery.

Used to protect electrical systems from lightning strikes and voltage surges, reducing the risk of equipment damage and downtime, suitable for both residential and industrial facilities.

Used for circuit overload and short circuit protection, automatically cutting off dangerous currents to ensure the safe operation of lines and equipment.

It aggregates the outputs of multiple photovoltaic modules, performs current merging and protection, and improves the efficiency and safety of solar power generation systems.

It automatically melts when the current is abnormally high, preventing damage to components and making it a reliable overload protection device in the circuit.

It monitors voltage changes and automatically disconnects power when the voltage is too high or too low, protecting sensitive equipment from damage.

The ability to quickly switch between main power and backup power to ensure continuous power supply is especially critical for backup power systems.

It is used for centralized circuit management and safe distribution, is easy to install, and is suitable for homes and various commercial locations.
