Soft starter control cabin

Overview

The soft start cabinet is mainly used to start all kinds of high-power motors. The soft start is used to replace the traditional starting method to achieve smooth start, reduce the starting current, and reduce the mechanical impact of large current on the motor when the motor starts, and the impact on the power grid. Improve power quality and save energy. The use of locked-rotor protection and fast protection to avoid mechanical failure or locked-rotor blockage causing the motor to overheat and burn out, reduce the voltage drop caused by larger currents, affect other electrical appliances, reduce wear, extend the service life of the motor, and save mechanical maintenance costs.

 

Features

◆It has protections for overload, over current, phase loss, over voltage, under voltage, etc., without the need for external integrated motor protector

◆The internal copper bar is used for connection to improve the electrical performance of the product

◆Three-dimensional layout is more reasonable

◆Convenient for installation, debugging and setting

◆With fault Chinese character prompt and memory function

 

Conditions of Use

◆Power supply voltage: three-phase AC AC380V (±15%), 50 Hz/60 Hz (±2%)

◆Starting current; starting current limit from 0.5 to 5 times

◆Rampdown time:0s~60s

◆Soft base value voltage:30%Ue~70%Ue

◆Sudden jump start time:0.1s

◆Environmental requirements: the ambient temperature is between -10℃~40℃; for every 1 ℃increase above 40 ℃, derating is 2%; relative humidity does not exceed 95%. No condensation, no flammable, explosive gas, no conductivity Dust and good ventilation. If the altitude exceeds 1000 meters, the capacity should be reduced accordingly, and the current will be reduced by 0.5% for every additional 100 meters above 1000 meters.
