Features • Increases life of 1-phase squirrel motors and mechanical drives • Devices available in 2 enclosure version: IL 9017: depth 61 mm with terminals at the bottom for installations systems and industrial distribution systems according to DIN 43 880 SL 9017: depth 100 mm with terminals at the top for cabinets with mounting plate and cable duct • For single phase motors up to 1.5 kW • Adjustable ramp time and starting torque • Semiconductors will be bridged after start up • LED indication • Width 35 mm Applications • Drives with gears, belts or chains • Conveyor belts, fans • Pumps, compressors Function Softstarters are electronic devices designed to enable 1-phase induction motors to start smoothly IL 9017. Slowly ramps up the current, allowing the motor torque to build up slowly. This reduces the mechanical stress on the machine and prevents damage to conveyed material. When the motor is up to full speed the semiconductors in IL 9017 are bridged to prevent internal power losses and heat build up. Principle of Operation Terminal L1 is connected to the mains contactor, terminal N to neutral, the motor is connected to terminals T1, T2. As soon as power is connected to terminal L1, the softstart will commence. Potentiometer "tan" (1 - 10 sec.) adjusts the ramp time (time the motor takes to get to full speed) and potentiometer "Man" adjusts the start voltage (20 - 70 % Vnom). When the softstart is complete the internal semiconductor is automatically bridged.
