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

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.

5.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


Starting Mode 

Current limiting starting mode 

a)The soft starter will be under current starting mode when code F9 is set to O (current limiting). Figure shows the current change wave of the motor under the current limiting mode. 11 is the set starting current limiting value, when the motor starts, the output voltage will increase rapidly until the current of the motor reaches the set current limiting value 11, and the current of the motor will be kept under such value, then with the increasing of the output voltage, the motor will speed up gradually, and when the motor reaches the rated rotation speed, the bypass contact will close, the output current will drop rapidly to the rated current IE of the motor or less, and the whole starting process completes. 

b)When the load of the motor is relatively light or the set current limiting value is relatively high, it will be normal that the maximum current may not reach the set current limiting value. Generally, current limiting starting mode applies to the occasions where there're strict limiting requirements on starting current.

Voltage ramp starting

a)The soft starter will be under voltage starting mode when code F9 is set to I (voltage). Figure 12-2-1 shows the output voltage wave of the output ramp starting. UI is the starting voltage value at start, when the motor starts, if the current of the motor is within the range of the rated value 400%, the output voltage of the soft starter will increase to UI rapidly, then the starting parameter set according to the output voltage will rise gradually, and the motor will accelerate smoothly with the rising of the voltage and reach the rated rotation speed when the voltage reaches the rated voltage Ue, then the bypass contactor will close and the whole starting process completes.

b)Starting time: t is the control parameter calculated from the standard testing condition based on standard load. Taking this parameter as the criteria, thePRS 3000 series soft starter enables the motor accelerates smoothly through controlling the output voltage to complete the starting process. This parameter is not the mechanical control time t which has nothing to do with if the motor accelerates smoothly or not. Given this, when the load is relatively light, the starting time will be less than the set starting time, and it will be normal as long as the starting process completes smoothly. Generally, the voltage ramp starting mode applies to the occasions where high requirements are not placed in the starting current but in the starting smoothness.
