Induction motor soft starters
soft starter is an ideal replacement for star/delta conversion,
self-coupling voltage reduction and magnetron control voltage
reduction devices etc.Soft starter features
Soft starter typical applications
- Select customizable parameters through simple programming according
- Three startup types are optional, it's convenient for a motor soft
starter to control different motor loads.
- Detect motor start-up feedback voltage to achieve closed-loop
control, to ensure electric motor start successful in variety load
- Three start-up modes: voltage ramp start mode can get maximum
output torque; constant current soft start mode can limit start-up
current maximum; direct soft start mode can start motor soft
- Programmable delay start and chain control mode.
- No requirements of input phase sequence.
- Start/stop time can be changed easily.
- With various protection functions: over-current, 3 phase current
unbalance, overheating, phase lost and motor overload protection.
- Dynamic fault record function, it's easy to find fault reasons.
- Online check the largest starting current and the maximum operation
- Fieldbus dynamic control and monitor the soft starters for easy
network system control.
- Character display: LCD screen displays various working parameters,
text prompts under programming and fault conditions.
Pumps - the soft-stop function ease water hammer occurs during stop
period, saving the system maintenance costs.
Ball mill - the voltage ramp start-up can reduce gear torque
wearing and reduce maintenance workload, saving time and costs.
Fans - reduce belt wearing and mechanical shocking, saving
Compressor - achieve smooth start by limiting current to reduce
motor heating and prolong motor service life.
Belt conveyor - achieve smooth and gradual starting process by soft
starters to avoid shifting and spillage.
