Yung economic electromechanical more than just specializing in high frequency machine inverter repair business, but also long-term to help provide technical Q & production problems encountered by a lot of equipment in the shop floor, often by telephone engineer Yung economic solutions will be able to exclude. 1, high frequency machine inverter repair the energy-saving principle: motor hard start to cause a severe impact on the grid, but also the requirements of grid capacity is too high, baffle and valve damage greatly startup current and shocked extremely detrimental to the life of the equipment, piping. Frequency energy saving device, the soft-start function will make use of the frequency converter start-up current from scratch, the maximum value does not exceed the rated current, reducing the impact on power supply capacity requirements, extended equipment and valves life saving equipment maintenance expense. 2, the high frequency of the high degree of protection inverter repair features: power range: three-phase 380 to 460VAC 1.5KW ~ 550KW; high starting torque will be able to output 150% rated torque: zero speed; high overload capacity of 150% overload one minute more than 2 times the rated current of the uniform flow capacity; precise speed control: the speed control accuracy is up to 0.2%, the output frequency accuracy of up to 0.01%; precise torque control: torque control accuracy of 5%; higher harmonic restrain: of 18.5KW and the more built-in DC reactor; maximum output frequency: 400Hz. Has been the high-frequency machine inverter repair are the issues of concern to each customer, Yung economic electromechanical committed to the maintenance of industrial automation products for many years, always address the urgent needs of customers.
