55KW soft starter with squirrel cage three phase asynchronous motor load piston type compressor
series soft starter has the following characteristics:
1. 16 SCM control, intelligent all-digital display;
2. can be put into practice a soft starter control multiple motors;
3. Starting modes: Current limiting starter, Voltage ramp start , Kick start +current-limiting start, kick start +voltage ramp start . Current ramp start . Voltage current-limiting double closed -loop start .
4. free stop and soft stop , The stop time from 0 to 60 seconds can be arbitrary choosed .
5. Over current , Overload , Open phase, instantaneous stop and other fault protection .
with the flow, over loading, lack phase, instantaneous stop, and other malfunction protection;
6. Easy installation, simple operation, strong function and reasonable prices;
Technical Indication for JKR2 Series Soft Starter
