SD 1000 1000 Volt Air andLiquid Cooled Variable Frequency Drive
The Magnetek SD1000 Air and Liquid Cooled Variable Frequency Drives (VFD) can operate applications ranging from simple variable or constant torque, to sophisticated networked systems.
The M-FORCE SD1000 Air and Liquid Cooled family of VFDs builds upon the proven control design platform used on Magnetek’s M-FORCE SD500 traction drives. Each drive is custom designed to handle common mine voltage of 950 Volts AC, and power engineered using the latest IGBT technology. The drive offers four modes of control, network communication options, application-specific drive software, and standard plus optional input/outputs to fulfill your specific requirements.
This rugged and reliable drive is designed for tough mining environments. It is available as a panel-only or mounted in an enclosure, providing the right environmental protection. The dual ratings, Normal and Heavy Duty, enable the most economical match of overload capacity and starting torque for the application. High-slip braking can eliminate the need for dynamic braking resistors for high inertia loads.

Product Features
Our standard factory programmed drive is ready to run right away. For operational simplicity and clarity, the LCD operator display has 5 lines x 16 characters, and can be set to one of 7 languages. The intuitive keypad includes parameter copying to move a chosen set of parameters between drives. If the application requires programming, the SD1000 Air Cooled VFD makes it easy. Parameters are grouped in easy- to-use sets; Quick Start and Advanced, to enhance parameter and data management.
The M-FORCE SD1000 supports the industry’s open architecture and open connectivity demands with network communications choices such as DeviceNet, Profibus-DP, and others. Drive coordination with other equipment is simplified with inputs and outputs for digital pulse train, 4 to 20 mA, -10 to +10 V, and an assortment of programmable contacts.
