Medium-voltage Magnetically-Controlled Soft Starter
Sinopak Medium-voltage soft starter adopts magnetically controlled reactor (MCR) to limit motor starting up current. It has the features: High control precision, large starting capacity, strong insulation performance and small volume etc. The equipment can be widely used for various large-scale motors such as: fans, water pumps and compressors etc.
Features
Sinopak magnetically controlled soft starter consists of the incoming line, switch, magnetically controlled reactor and controller. The equipment controls MCR reactance through changing magnetic permeability of iron core with DC excitation current, so it is called magnetically controlled soft starter.
The starting capacity is large, and it can achieve starting control of a 20000KW motor. Adopting dual-DSP and FPGA as the main control chip, so that the system has the strongest processing capacity, to ensure the starting current’s control precision. The reactor’s high-voltage coil made with one-time vacuum casting molding technology of epoxy has advanced technology and strong insulation performance. Small volume, free maintenance, operation with the colorful touch screen in Chinese, and easy to operate. Can achieve remote operation of DCS.
