Overviews
The Eaton NPR48 Series of rectifier modules is designed for a wide range of telecommunications applications including
switching, wireless, and transmission.
flexible, efficient, and reliable DC power source. It is designed for operation at up to 70°C (158°F) and under a wide range of AC power conditions.
The NPR48 Series rectifiers are up to 92% efficient with optimum performance available at typical load currents. These
rectifiers also offer two output modes; either constant power or constant current.
* Fast on-line replacement of rectifiers (hot-swap)
* Automatic set-up from supervisory module
* Intelligent microprocessor controlled
* High power density
* High efficiency and unity power factor
* Wide AC supply conditions
* Wide output voltage range
* Constant power or constant current output modes
* Compliance with international standards
