Small volume, light weight, and high protective level.

Excellent mechanical driving system, stable performance.

Self error correction of the power supply s phase sequence and the function of phase disconnection warning protection

Self-regulation function, the machine can receive and feedback 4-20 mA current signals to the computer, DCS and PLC, both channels of input/ output signals adopt photo electricity isolation ( can withstand 2000 V surge voltage ).

Non-invasion design, free-opening commissioning, setting with the remote control, and achieve man-machine conversation with the window.

Full-Chinese characters display, provide good user interface.

Self- diagnosis technology of operation failures.

Over-heat protection function of the motor.

Using micro- electronic technique, computer technology, IR remote technology, magnetic-control switch technology, LCD digital display technology to substitute traditional control methods.

Bus control of operational network, the mechanism can achieve current popular various on-site bus functions by increasing different bus interfaces, such as Profibus etc.

The power supply can adopt different methods, such as three-phase three-wire system, three-phase four-wire system, and single phase etc.

The connection can adopt outgoing method with the aviation plug.

Installation method: Installed at any position at 360 o ( partial rotation

The locking unit can position the magnetic knob to position of some gear, thus can avoid accidents caused by misoperation of non-specialized person.
