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:
