3.Smaller & stable operating load, greater stepless
operating range

Unit lowest starting load is down to 7.5% and can achieve stable operation, greatly expand the usage range and
enhance the system stability
Unit load capacity range is wide to 7.5%~100%, in this range, the unit can achieve continuous stepless load
adjustment and stable operation, thus adjust the unit output more accurately according to user requirements

4.Bosch excellent industrial design HMI
