Type: Leroy Somer Digidrive SK 1.5T/SKB3400075 0.75kW Part Number LS4349429 is a simple compact senseless vector AC Drive frequency inverter

However, for more demanding applications, Digidrive SK AC Drive frequency inverter can deliver the benchmark functionality of its larger Solutions Platform products and at no extra cost on the base drive itself. Plug-in options, dynamic performance, PLC functionality and other benchmark features ensure that in more complex applications Digidrive SK can deliver more than the average general purpose drive – giving you lower cost solutions and better productivity in your motor control applications.
