Why Choose Us

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. 

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:

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:

Technical Characteristics
