1. Overview
This soft start controller takes an advanced microprocessor as the core, applies advanced software design methods and
the latest hardware technology, uses thyristor phase shift technology, and realizes the soft start and soft stop functions of
AC asynchronous motors, which has the multiple protection functions such as voltage, under-voltage, over-current,
overload, three-phase unbalance, short circuit, etc.
The soft starter covers 5.5KW~630KW, with reliable quality and good electromagnetic compatibility (EMC). It can be
widely used in heavy-duty equipment such as fans, water pumps, ball mills, crushers, conveyors and compressors. It is an
ideal replacement product for star/delta conversion, auto-coupling step-down, magnetic control step-down and other step-
down starting equipment.
1.1 Product features
⚫
Using high-performance single-chip microcomputer and digital logic control technology, it has strong anti-interference
ability.
⚫
Starting parameters can be flexibly set according to different loads to obtain the best current curve and best torque
control characteristics.
⚫
It provides a smooth and gradual starting process for the motor, reduces the impact of the starting current on the
power grid, reduces the vibration and noise of the equipment, extends the service life of the mechanical transmission
system, and improves the working environment of the workers.
⚫
The starting current can be adjusted according to the load to reduce starting loss and generate the best torque with
the minimum current.
⚫
There is no phase sequence requirement for input power.
⚫
It can be set to free parking and soft parking, and the soft parking time can be adjusted.
⚫
With standard RS485 interface and ModBus protocol (order statement).
⚫
Using 4 x 8 LCD, parameter modification, easy and intuitive operation.
⚫
The product has novel structure, reliable performance, strong function and easy installation and operation.
1.2 Structural features
⚫
Soft starter:Natural air cooling, external AC contactor.
⚫
Intelligent starting cabinet: Exquisite structure, simple installation.
