Description
The line starts with compact models, some of which are single-phase. The SD150 is rated for 0.4–2.2 kW and goes to small pumps, fans and conveyors. The SD300 series sits between it and the flagship. The top SD750 covers 1.5–2200 kW and delivers an output frequency of 0–599 Hz, which is enough even for high-speed motors. Three special versions are built on the SD750 base. The SD750K has a compact enclosure, the SD750SP powers pumps from solar panels, and the SD750FR returns braking energy to the grid instead of using a braking resistor.
How to choose
First the grid voltage is checked against one of the three supply classes, then the rated power and current of the motor. For duties with frequent braking, such as hoists or centrifuges, it makes sense to take the regenerative SD750FR. Medium-voltage motors of 2.3–13.8 kV move to the XMV670 / XMV660 Outdoor series, and where speed control is not needed, a V6 soft starter for 16–1250 A is enough.

FAQ
What is the power range of the SD frequency converters?
From 0.4 kW in the SD150 series to 2200 kW in the SD750, while the SD750 itself starts at 1.5 kW.
What output frequency does the SD750 deliver?
From 0 to 599 Hz, so the drive also works with high-speed motors.
What is the SD750SP?
The solar version of the SD750 for pumps, powered from photovoltaic panels. It is used for water lifting and irrigation at remote sites.
What is the regenerative SD750FR converter for?
The SD750FR returns the motor braking energy back to the grid, so machines with frequent braking do not need a braking resistor.
For which grid voltages are the SD drives made?
Versions for 230 V, 380–480 V and 525–690 V are available, which covers residential and industrial grids.
