Low wearing and easy to go motor start
Softstarter with softstop function
The new softstarter generation Ministart GF 9016 of DOLD controls asynchronous motors up to 75 A. By a special control of the semiconductors it is easy on motor and supply mains.
Ramp up/ramp down time and starting torque are separately adjustable. This allows a precise setting for each individual technical demand. Special additional emc protection is not necessary during operation due to the integrated bypass contacts. This reduces size and cost. As the unit can be connected for W3 operation, the BF 9016 37 kW can be used on 55 kW motors offering more cost saving.
As option current control on softstart is available. In this case the current can be limited to an adjustable value. So a controlled and low wear operation of motors is provided.
Additional features, like kick start function, integrated motor and heat sink temperature monitoring and removable load terminals allow universal usage in different application areas. These are door and gate drives, pumps, fans, air conditioners, conveyor and transport systems and many more.
