Product display
1. Materials is full efficient and reliable
Military-grade circuit board, advanced patch technology, seckill in-line design. Adopting high-quality components, DC power supply is more efficient
2. Simple design but not simple functions
Ultra-simple shape design contains 20 years of rigorous and precise production technology to maximize portability and achieve maximum application with small machines.
3. Metal plastic, Rugged pressure
The selection of sturdy and pressure-resistant hardware material body, thickness is about 2mm. The fuselage vents conform to the airflow principle. Reject all counterfeit materials and refurbishment.
4. Super movement, Multiple protection.
The small model has a big effect. Compared with the large-volume power supply, it has the same protection function and performance. The performance linear power supply is higher, overload, over-voltage, over-current, current-limit, multiple protection, and be relieved to use.
