Problems solved by technology

However, the numerical control voltage is processed by multiple sets of transformers, and can only be adjusted continuously at 0-10V
Generally speaking, some products have a small frequency range, the frequency range is limited to a limited fixed frequency, the water treatment function is relatively simple, and some products have a small and fixed output voltage, which is difficult to meet the power requirements of different water treatment equipment. Meet the requirements of comprehensive water treatment functions in multiple aspects such as sterilization and algae removal, scale removal and anti-scaling, and anti-corrosion
