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.

Through the inbuilt RS485 standard interface, WSTR 3000 series soft starter can connect with PC and PLC and other hosts to conduct serial communication. The command of the host can control running or stop of the soft starter, monitor the running status of the soft starter and modify its functional data.

Major functions 

1.Input of stop running command. 

2.Monitoring of the running status 

3.Real-time tracking (tabular display of the running information)

4.Read-once, write-once and saving to files of function codes. Please consult our company separately for the communication software.

Connection Of The Main Circuit And The Grounding Terminal

(I) Main circuit power input terminal (R,S, T) 

a.Connect the main circuit input terminals R, S, T to the three-phase AC power through the circuit breaker for circuit protection or circuit breaker with leakage protection without considering the connection sequence

b.Do not use ON/OFF of the main circuit power to control running and stop of the soft starter, instead, such should be controlled by means of the control terminal or RUN and STOP buttons in the keyboard panel of the soft starter upon power on. 

c.Do not connect the soft starter to the single-phase power. 

(2) Output terminals of the soft starter (U ,V ,W ) 

a.Output terminals of the soft starter should be connected to the three-phase motor in correct phase sequence. If the rotation direction of the motor is incorrect, switch connection of any two phases among U, V and W.

b.The output end of the soft starter shall not be connected to capacitor or surge absorber. 

c.If the wire between the soft starter and the motor is very long, the distributed capacitance between the wires will generate high­frequency current which may cause over-current tripping, leakage current increasing and poor current display precision of the soft starter. Therefore, it is suggested that the motor connection wire should be no more than 50m.

(3) Grounding terminal of the soft starter (〨 G)

a.For safety and noise reducing, the grounding terminal G of the soft starter must be well-grounded. To prevent electric shock and fire accidents, the metal enclosure and frame of the electric equipment should comply with the requirements of the national electronic procedures.
