Highway Isolation Converter

Product Overview:

The LW series remote power supply for highways is a new generation of dedicated power transmission equipment designed and manufactured using modular and digital program-controlled technology, specifically addressing the characteristics of high reliability requirements for high-speed power transmission, long-term continuous operation, dispersed loads over long distances, and unattended operation. This series of power supplies is an AC power supply equipment that integrates control, display, protection, and communication functions with a power generator as its core.

Highway Barrier Converter Product Description:

The LW series remote power supply for expressways produced by our company is a high-speed dedicated long-distance power transmission equipment, consisting of an intelligent source-end power generator and a terminal power isolation converter. The power supply adopts an AC-DC-AC structure internally, which converts DC into clean and controllable sine waves. After voltage boosting, it is transmitted to the terminal power isolation converter and output to the load through an isolation transformer, eliminating grid interference. The power generator uses a phase-shifting transformer for input and six-pulse rectification, achieving a power factor of up to 0.99. In case of power supply abnormalities, it can automatically switch to grid power supply mode, ensuring safety and reliability. During maintenance, it can also be manually switched to grid power output, providing convenient and efficient operation.
