1、This motor controller can be used for water pump, fan, air vehicle or ordinary motor soft start. 2、Such motor start module can replace soft start of inverter or soft star-delta starting, etc. 3、Wiring is super simple and no need to connect bypass contactor, while motor start board is powerful. 4、Three-phase motor soft start module solves the problem of slow start of 1-20KW low power motor. 5、Soft start controller supports simple installation, not require particularly complicated operations. Item Type: Motor controller Model: TSR-10WA-R1 (1KW) (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 large, the heat sink should also be matched. Applicable Places: It can be widely used in fans, pumps, belt conveyors, ball mills, conveyors and compressors.It is an excellent replacement for traditional star-delta conversion, auto-coupling voltage reduction, magnetron voltage reduction, frequency converter and other voltage reduction starting equipment. Also, it is safe and reliable. 1 x Overall (Module + Radiator)
