Rectifier AC to DC Short Introduction:
Â
The Eaton APR48-3G Access Power Rectifiers are designed specifically for network access applications such as cellular base stations, customer premises equipment and road-side cabinet installations.
The new generation 3G architecture is reliable, power dense and compact. The high power density allows as little as 1U of rack space to be occupied by power, therefore, Eaton APR48-3G maximizing space available for telecom equipment.
The APR48-3G is a high powered rectifier with 1800W output. It is designed for operation at up to 7C (158F) and under a wide range of AC power conditions.
The APR48-3G also has power factor correction and is up to 92% efficient, with optimum performance available at typical load currents. Together these give the APR48-3G some of the lowest running costs for any DC power system of its type available.
Operating with the Eaton SC100 or SC200 system controller, the APR48-3G rectifier modules will provide years of cost-effective, and trouble free service for your 48V network access equipment.

Description
The Eaton NPR48-ES Energy Saver Rectifier is designed for communications network operators who are striving to cut energy costs across the network, and/or to meet aggressive carbon footprint reduction targets.
Operating with well over 96% efficiency, it produces at least 50% less waste energy than most other modern rectifiers, and with potentially greater savings over older infrastructure.
The NPR48-ES Energy Saver Rectifier harnesses the technology of the APR48-ES 2kW rectifier to offer a powerful 3kW of output power.
This rectifier features intelligent digital signal processing for enhanced control, producing peak efficiency in excess of 96% for typical operating loads, while also maintaining a very high minimum operating efficiency of 95 to 96%, over a very wide range of loads.
The high power density, short depth and flexible mounting options makes the Energy Saver Rectifier well suited to limited space applications such as ETSI and road side cabinets.
The Energy Saver Rectifier is fully compatible with the existing Eaton SC200 system controller and it is one of the easiest rectifiers to use, with a simple plug-and-go insertion. It operates under a wide range of AC power conditions and in temperatures at up to 70C (158F).
