ZQS580 Series

Soft Starters

List price:0.00

Price:0.00

‍ZQS580 series intelligent motor soft starter is a new type of starting equipment with the current international advanced level produced by power electronic technology, microprocessor technology and modern control theory technology. This product can effectively limit the starting voltage of asynchronous motors when starting, and can be widely used in heavy-duty equipment such as fans, pumps,conveying and compressors. It is an ideal replacement product for step-down starting equipment such as star/delta conversion, auto-coupling step-down, and magnetron step-down.nce. Adopt ST Microelectronics, Microchip, ON Semiconductor, Texas Instruments and other chips, with strong anti-interference ability and stable performance. Six of them are suitable for various load types to achieve the best starting effect; Two stop modes: freewheel stop and soft stop. Various protection functions: power-on phase loss, running phase loss, starting overcurrent, running overcurrent,starting overload, running overload, current unbalance,overheating protection communication interruption, starting time overtime, motor overcurrent, three-phase current unbalance (unbalance degree can be set), overload (6 overload levels can be set). A variety of detection functions: A B C three-phase current detection. With 4-20mA analog output, RS485 communication interface (using Modbus-Rtu communication protocol), parameter setting, operation and monitoring can be carried out through the host computer to achieve highly intelligent control. The soft-start parameters can be set through the keyboard, the keyboard is hotswapped under the power-on state, and has the functions of keyboard parameter download and soft-start parameter upload. Liquid crystal display panel: It can display different working states of soft start. A variety of relay output functions: bypass output, fault output, programmable relay output(action stage can be set).
