1、 Product Introduction:
The NHAC series AC remote power supply system is a dedicated power supply system provided by Jinan Nenghua Electromechanical Equipment Co., Ltd. for the dismantling of provincial toll stations on highways, which includes a gantry system and a highway full process monitoring system. It can provide stable and reliable AC voltage stabilization power for long-distance outdoor equipment, such as dismantling gantry systems, full process monitoring systems, 5G mobile phone base stations, etc.
This system mainly consists of three parts: a power generator (also known as a local computer or upper computer), an isolated power converter (also known as a remote computer or lower computer), and transmission cables. The local end machine is installed in the power supply room of the toll station or service area on the highway, the remote end machine is installed next to the gantry system or various outdoor monitoring equipment along the highway, and the transmission cable is installed along the highway between the local end machine and the remote end machine.
