Устройство плавного пуска под 660

Motor Soft Starter under 660V We are looking for experienced Distributors and Agents worldwide! Application scope It is used for the soft start and protection of the low-voltage squirrel cage motors with capacity ranging from 7.5kw to 500kw Working principles The parallel thyristors are connected into stator circuit of the low-voltage motors. Voltage drop start is achieved by adjusting the break-down angle of thyristors, which is controlled by the 32-digit ARM micro-controller. Prformance characteristics Multiple starting methods Current limit soft start, voltage index curve, voltage ramp linear curve, current index curve; Programmable kick start starting torque and starting current limit. Advanced communications functions RS485 communicatinos interface adopted to enables the users to internet connection control. Built-in Modbus standard protocol adopted, easy for configuration connection. Double-data functions Two sets of motor control data for motors with different power ratings, making the control over two motors of different power ratings possible. Multiple stoppage modes Programmable soft stoppage, free stoppage, break stoppage, soft stoppage plus brake stoppage. Dynamic memory for errors 15 accidents can be recorded, easy for trouble-shooting. Well-developed protection function Protections against overload, overheat, phase failure, power loss and micro-computer by means of feedback on current and load details. Notes: The starter unit can be supplied alone, or, the starter panel can be supplied with by bypass switch and power switch arranged inside the same panel depending on requirement of users Standards adopted GB/T3797-1989 Q/FZR4-2001 GB/T12747.
