Why Choose Us

WSTR 3000 series soft starter possesses complete protection functions to protect the operation security of the soft starter and the motor. Here is Motor thermal protection tripping time curve based on IEC60947-4-2 standard is shown as follows:

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

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:

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.
