SJ-P1 Variable Frequency Drive

Posted by Hitachi America, Ltd. (booth # S1894)

Summary of Innovation

Hitachi's SJ-P1 new variable frequency drive is now UL rated for single phase input power applications, including very high efficiency PMAC type motors that surpass the rating levels of high efficiency inductions motors in most applications. This industry first IVMS feature allows the operation of PMAC motors in high torque applications, at slow speeds. No longer are PMAC motor applications limited to variable torque loads.

Innovation Statement

The new Hitachi SJ-P1 will not become obsoleted as your application may change into PMAC or BLDC motor technologies.


The SJ-P1 incorporates an exclusive and patented feature allowing the use of PMAC in applications such as conveyors, as well as other contact torque loads while saving energy and operational costs.
