Hitachi SJ700B AC Drives

A series of general industrial electric drives SJ700B from the company Hitachi They are equipped with standard control capabilities for asynchronous electric motors and can be used in many industries, in particular for ventilation, pumping systems, conveyor installations. A universal set of functions for ease of use and flexible adjustment of production cycle parameters. High computing power, vector control technology with sensorless control (optional feedback module is also available). The applied protective measures ensure stable and safe operation of the drive.

A wide range of models with a power range up to 160 kW, a wide range of optional units for expanding and strengthening the basic equipment is presented. The control panel is included as standard, a convenient screen and an LED indication of the current status, additionally a unit with a data backup function and a potentiometer can be installed.
