Feature: 1. Motor controller can be used to replace soft start of inverter or star-delta soft starting, etc. 2. Also, soft start controller supports wide application on water pump, fan, air vehicle or ordinary motor soft start. 3. Keeps super simple wiring, motor start board is powerful and there is no need to connect bypass contactor. 4. Three-phase motor soft start module solves the problem of slow start of 1-20KW low power motor. 5. With simple installation, the soft start controller does not require particularly complicated operations. Specification: Item Type: Motor controller Model: TSR-30WA-R1（3KW )(with soft start without soft stop) Suitable for Three-Phase: 380V Compatible: 50-60HZ Radiator Voltage: Default 220VAC Soft Start Time : 30 seconds adjustable (time rise refers to 0-380V). Starting Voltage: Adjustable slow start from 150-250V to rated voltage (380V) Two Ways to Use: 1. When the switch is closed, the soft start of the main power supply starts. 2. Use the switch to control, start by closing the soft start, stop when disconnected. Selection: 10A below 1KW, 20A below 2KW, 40A from 3-4KW, 60A from 5-6KW, 80A from 7-8KW, 100A from 8-10KW, 150A from 11-15KW, 200A from 20KW .If the heat sink is larger, the heat sink should also be matched. Applicable Places: With wide application on fans, pumps, belt conveyors, ball mills, conveyors and compressors as an excellent replacement for traditional for star-delta conversion, auto-coupling voltage reduction, magnetron voltage reduction, frequency converter and other voltage reduction starting equipment, safe and reliable.. Package List: 1 x Overall (Module + Radiator) Note: Three-phase motor soft start module needs no switch contactor, working for a long time.
