[Applications] ★ electrochemical industry: plating, corrosion, enabling can be used for electronic aluminum foil, chlor-alkali, carbon, silicon carbide production; ★ industrial plating, electrolytic copper foil with high precision, low ripple hard chrome plating; ★ industrial metals surface electrophoretic coating and electrophoretic coating aluminum surface; ★ precision measurement, medical electronic equipment; ★ imported power electronic and electrical equipment; exports of electronic and electrical product testing; ★ CNC machine tools, textile, automated production lines; ★ for generator supporting the composition of plant performance uninterruptible power supply system. [Reason] generated power problems: power plants produce is a certain limit, at the time of peak load capacity than its electricity sector must buck power supply, which leads to the formation of the entire grid undervoltage; in electricity low peak load is very light, so that would make the grid voltage increases cause the entire grid to form two overvoltage; when the power factor is too low, the electricity sector on the use of the grid to join or disconnect the power factor capacitor to adjust, then will provoke a spike voltage in the power grid. Reports from the laboratory []: major cause of sophisticated electronic equipment damage is the voltage surge that short-term (about 10ms) or long-term over-pressure, which accounts for 45.3% of all causes of damage, lightning 9.4%, leaving the device the machine is not working properly because the error voltage is too low, accounting for 87% of the pulse peak power accounted for 9%. Typically a computer 120 times the average monthly power problems encountered on the computer, the power supply can cause problems both keypad lock; aging hardware and other relatively minor adverse effects, may also lead to complete loss of data or motherboard burning and other more big accident.
