Products Description
Function introduction of boost frequency converter
1, single-phase to three-phase phase transformation function, 220v to 380v boost function, frequency conversion function;
2. It has most functions of general frequency converter, such as soft start function (reducing starting current and impact on power grid, which can replace soft starter), speed regulation function (stepless adjustment from 0 to rated motor speed), positive and negative switching function of terminal start and stop (controlling motor start, stop, positive and negative rotation through external switch, which can replace AC contactor), etc.
3. It has motor protection function, overcurrent, overload, overvoltage, overheating and short circuit protection, etc., which effectively prolongs the service life of the equipment.
