SD700K Compact Series – High-Performance Variable Speed Drives in a Compact Form
Maximum Performance in Minimum Space
Overview
The SD700K Compact Series delivers the advanced features of the SD700 family in a space-saving design, with power density up to 800 kW/m³. This makes it the ideal solution for projects where space constraints are critical.
Reducing its size by up to 2.5 times, SD700K offers professional project engineers greater flexibility and competitiveness when designing and executing electrical installations.
Designed with a top input power and bottom motor output connection, following the contactor wiring concept, it is supplied in two IP00 units (drive unit and input chokes), making it easy to install in custom cabinets or technical rooms according to Power Electronics guidelines.
Key Features & Benefits
- Power range: 63 kW to 800 kW
- The ideal solution where multiple motors are installed, offering significant space savings.
- High power density: Up to 800 kW/m³ — maximum performance in compact size.
