NASN rectifiers
NASN rectifiers bring advanced technology to the DC power industry. Innovative engineering combines the best in efficiency and reliability to meet the power requirements for a variety of system applications. This rectifier is specifically designed to recharge all types of stationary batteries for large utility, petrochemical and industrial uses.
The fan cooled rectifier module has extremely high density providing the most power in the least amount of space. A compact shelf accommodates four rectifiers per 19in 2U shelf and can be paralleled up to 5*2U 19in shelf.
Local and remote setup, adjustment and control is a simple, single-step process with the rectifier System Controller. By utilizing TCP/IP technology, complete configuration and monitoring of power equipment is possible through a Windows Internet Explorer browser.
We can provide turnkey solutions for outside plant, headend, telecommunications, industrial and renewable energy applications. We work to combine your small-, medium- and large-scale projects with the necessary installation resources.
