Vector Control Inverters

The SJ200 Series of inverters employs sixth-generation sensorless vectorcontrol technology.


The new Intelligent Sensorless Vector Control (SLV) needs no autotuning process and incorporates an Inverter System Power Module (ISPM). The SJ200 has new features that include an advanced trip-avoidance function, side-by-side mounting capability, built-in timing logic and analog input math (PLC) functions, DIP-switch hand-off ratio, removable control terminal connector, and RS-485 Modbus RTU communication interface. An optional NEMA-4X keypad kit permits panel mounting.
