FMS300 Intelligent Soft Starter Device

Product Introduction

The FMS300 series intelligent motor soft starter device is based on an advanced sixteen bit microprocessor and controls a high-power thyristor module to achieve soft start and soft stop functions for three-phase AC 380V asynchronous motors (squirrel cage type). It also has multiple optional protection functions such as overload, phase loss, overvoltage, undervoltage, etc. This product is mainly used in conjunction with a complete set of control cabinets, and requires the connection of corresponding specifications of bypass contactors during use. The product specifications cover 5.5KW~600KW three-phase AC asynchronous motors (squirrel cage type).

The product is widely used in motor transmission equipment in important national industrial fields such as metallurgy, petroleum, fire protection, mining, and petrochemicals. It is an ideal replacement product for traditional star delta starting, reactor starting, and autotransformer pressure reducing starting.

Product Features

Three starting methods: voltage ramp starting, current limiting starting, and heavy load starting

◆ Voltage ramp soft parking, free parking

◆ Programmable delayed start mode, can be turned into chain control, programmable fault contact output

◆ No phase sequence requirement for input power supply

The starting time and stopping time can be programmed and modified

◆ Multiple protection functions such as overcurrent, three-phase current imbalance, overheating, phase loss, motor overload, etc

◆ Dynamic fault memory function, easy to find the cause of faults

◆ Can search for the maximum starting current and maximum operating current of three phases online

◆ Digital tube code display and LCD screen Chinese character display are optional

PRODUCT FUNCTION

Start mode

◆Current limiting: limit starting current, reduce starting voltage drop, adjust freely, keyboard settings

◆Voltage ramp type: provides a smooth and gradual starting process for the electric motor, reduces the impact of starting current on the power grid, lowers equipment vibration and noise, and extends the life of mechanical transmission

◆Heavy load starting type: capable of outputting maximum starting torque

Parking method

◆Free parking

◆soft stop

control mode

◆Input: Passive switch signal

◆Output: Passive contact of relay

system control function

◆Equipped with programmable input and output contacts, built-in with various load intelligent programs, real-time detection of system operating conditions

◆Comes with a Chinese menu for human-machine dialogue, setting various parameters and programming, etc

◆Analog current signal 4-20mA output function

◆Equipped with keyboard control and remote control switching function to ensure the safety of equipment maintenance personnel

◆Delay relay function, programmable output contact time of delay relay

◆Fault output relay, if the system malfunctions, this relay will activate, and the fault will shut down and reset automatically, which is programmable

◆The output relay of the self-control bypass contactor will activate when the starting process is completed

◆Delay start function, can set a delay start of 0-240s, and has a countdown display (two-wire control mode is effective)

◆Can achieve a soft start to drive multiple electric motors

System protection function

◆Built in electronic quick break protection, does not require external acceleration of melting. If there is a short circuit fault in the lower port before starting, during starting, running, or soft stop, the system can achieve self-protection and alarm action

◆Overvoltage protection

◆overload protection

◆open-phase protection

◆Phase reversal prevention protection: The upper port will not start and will sound an alarm if it is reversed (optional)

maintenance function

◆Fault self diagnosis (short circuit, overvoltage, overload, phase failure, locked rotor)

◆Fault display and relay contact output
