Overview
The GE Multilin UR-SHA Power Supply Module delivers highly reliable excitation for synchronous generators and industrial power systems. Designed for both harsh and controlled environments, it ensures stable DC voltage and precise current output. Moreover, its modular architecture supports flexible integration with existing control systems, making upgrades seamless. The unit accommodates automatic voltage regulation (AVR) or manual operation, allowing operators to adjust voltage output accurately under varying load conditions. In addition, the UR-SHA module incorporates comprehensive protection features, safeguarding equipment against overvoltage, overcurrent, and abnormal excitation. Engineers benefit from its dual-channel redundancy, guaranteeing uninterrupted operation during maintenance or unexpected faults. Therefore, the UR-SHA module is ideal for power plants, heavy industry, and utility applications demanding high performance and reliability.Specification
