Why Choose Us

Yueqing Winston Electric CO.,LTD has made further technical improvement in both the software and the structure of the soft starter according to the market demand. The soft starter provides complete motor protection functions including start control, running and overloading, phase failure, three-phase unbalance, over-voltage, under-voltage protection and so on. As another great achievement in the intelligentization of motor protection and networked technology application, it simplifies the circuit, reduces the volume, cuts the coat, makes installation and using more convenient.

Installation direction and space: to enable good ventilation and heat dissipating conditions during using of the soft star ter, the soft starter should be installed vertically with enough space for heat dissipating left around the equipment. The allowable minimum spaces are shown in figure 2.1 and figure2.2. 

In the event that the soft starter is installed inside the cabinet, besides the above requirements, the cabinet selected should be with good ventilation at the top and bottom, as shown in figure 2.3.

Technical Characteristics

1. Unique SCR trigger closed-loop control algorithm

Unique SCR closed-loop control, specially designed for standard and heavy loads. The user can select the current limit start and the voltage ramp start according to the load condition to achieve an absolutely smooth torque-free oscillation start effect.

2.Control accuracy, real-time efficiency

High-performance CORETX-M3 32-bit core CPU for center control, fast speed, high precision, strong anti-interference ability

3.Beautiful appearance

Patented main circuit three-in and six-out structure, built-in current transformer scheme, convenient wiring and high reliability

4.Optional standard MODBUS-RTU protocol

5.Integrated advanced protection

It has protection functions such as input and output phase loss, overload, overcurrent, phase current imbalance, thyristor over temperature, etc., to protect the motor and related equipment in all directions.

6.Full refractory

90kw or less is a fully molded shell structure, processed with flame-retardant ABS material. The upper cover of 90KW and above is made of plastic shell structure, and the main frame is made of aluminum-zinc plate material. It has heat resistance and corrosion resistan

6.CE.

7.External lead panel

The panel can be externally led to the operating surface of the device for remote operation through the fuselage interface, which is convenient for on-site use.

8.Simple maintenance

A monitoring signal coding system consisting of a 4-digit digital display that monitors the operating conditions of system equipment 24 hours a day, while providing fast fault diagnosis


MODBUS Communication Protocol

Modbus is a kind of serial asynchronous communication protocol with RS485 as the physical interface. Being designed for Modicon PLC, it has the structural features of PLC. In network control, it can read and write the PRS 3000 as if it were a PLC. It can project the start and stop control, status information (current, fault etc.) and function parameters to the holding register (4:XXX). Its read and write control shall be conducted through the PL master station. When connected to other Modbus equipment, connection should be conducted as per the diagram below:
