1.operate at different segments and various running speed by setting programme asper different raw materials.2.shows better performance when start-up in those insteady voltage areas.3.different processing speed to meet different producing and processing pared with DH-DL60A,it works more smoothly with lower ction of monitoring such as voltage,electric current and running ction of giving a caution to the instant overload,over voltage and over currentduring its operation so as to reduce the accidents. producing area:shijiazhuang ,china payment:LC or TT supplying capacity:100000
