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.

WSTRD series Motor Starter has a Chinese & English LCD display to real-time display current, voltage and other operating status. The help information can be assessed when the soft starter is not in the soft start/ soft stop status or the setting status; press Yes(button for confirmation), then press the up/down buttons to read the prompt messages.

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.

Description of Protection Functions

WSTR 3000 series soft starter possesses complete protection functions to protect the operation security of the soft starter and the motor. During operation, the protection level and protection parameters should be properly set base don different circumstances. 

● Over-heating protection of the soft starter: the protection will start when the temperature rises to 80℃±5℃, and it will stop when the temperature falls to 55℃(lowest). 

● Delayed time of input phase loss protection: <3s. 

● Delayed time of output phase loss protection: <3s.

● Delayed time of input three-phase unbalance protection: <3s. Taking the deviation of current in each phase is over 50%10% as the criteria, when the load current is less than 30% of the nominal rated value of the soft starter, it is confirmed that the deviation will increase. 

● Protection time of over-current during starting: the protection time shall be continued to be longer than 5 times of the maximum operating current of code F5, 

● Delayed time for power under-voltage protection: when the power voltage is under the extreme value 40%, the protection time< 0.5s, when the power voltage is below the set value, the protection time< 3s. 

● Delayed time for power over voltage protection: when the power voltage is over the extreme value 130%, the protection time< 0.5s, when the power voltage is over the set value, the protection time< 3s. 

● Delayed time for load short circuit protection < 0.1 s, if the current is more than IO times of the nominal rated value of the soft starter, this protection shall not replace the fuse or short circuit protection device. 

The above time parameters are the periods from the valid signal being detected to the tripping protection directive being given; these parameters are for information only. In the event that the protection functions of the soft starter fails to meet the requirements of customers, special protection devices should be installed to ensure the safety.
