Hitachi SJ300 AC Drives

Converters SJ300 from the company Hitachi They are versatile in use and have in their arsenal a wide range of power models for capacities up to 400 kW. Thanks to the advanced capabilities of sensorless vector control, a high level of starting torque was achieved. Also, this series has excellent performance at low speeds, stable and accurate operations. Very compact dimensions in its segment, maximum ease of maintenance.

Numerous built-in algorithms and functions make it easy to achieve the desired result and adapt the drive to perform specific operational tasks. In addition to the standard version, the operator panel can also include a potentiometer and a data backup option.

Attention! Currently, this series has been discontinued and replaced with a new generation of SJ700/SJ700D/SJ700B products.
